American Welding Society Forum
Thanks for all you do John.
I think for those motivated towards self study that you cannot go wrong with the AWS Welding Handbook Volume 1 9th edition, The AWS Certification Manual for Welding Inspectors (for the questions), and whatever code book you have worked with the most or anticipating working with.
The body of knowledge listed for the CWI exam is almost completly covered in the AWS Welding Handbook. Get any welding book you can find and read it.
There is also a company that has some online training that is pretty good. The company is SonSet consultants.http://www.weld-procedure.com/freecwipartbhelp.html
Thats not to say there isnt any value in a class however things learned over a week or two are different than those studied over a period of time. There are, I am sure, some great classes.
Yup. Yours is still the only response. Once I get a few results I'll post a link.
I recently posted a survey in a "Welding Instructors" group in LinkedIn about which welding process you prefer to teach 1st. I have an identical copy of it here at http://goo.gl/forms/zcJ14w365f
. It would be cool to see what everyone here thinks (Unless you already answered from the LinkedIn post. The questions are the same, the data is just stored in a different location to keep it separate.
If this is not in accordance with any current restrictions on "link posting" etc.. let me know with a severe scolding.
Have a great day
There is nothing specific in the codes however that does not mean its not a good idea. I assign a specific and unique number to each test. That test ID number is linked to all of the information to the test. It is located at a specific orientation and location.
I have a procedure written that is part of our quality control program developed for welder testing if you would like to look at it. Probably much more complicated and "wordy" than it needs to be but sometimes I'm that way.
Pulsed Arc is Spray Transfer Mode. Or it was in older D1.1's.
Haven't gotten into a fact finding on it yet and willing to be pointed in the right direction as the where it Spray Pulsed is not prequalified.
Have a good day
More than likely the only reference to this can be found in the specification for the filler metal. This is a requirement for the manufacturers when qualifying the products. Not sure if it exist in A5.20 or not. Don't have a copy here. However regardless of what A5.20 says, they are NOT limits for production.
Have a nice day
This one probably would have been best posted in the safety section but no big deal to me.
The majority of the fumes will probably be generated by the filler metal or processing the base metal. Because the situation is infrequent and situations may change, source extraction is a great way to go. Air monitoring by an industrial hygienist would be the most surefire way to verify you are really looking out for your guys. There are also some great PAPR welding hoods available that may also be suitable solutions but in my opinion (which is mine), a safety professional is best consulted for safety issues just as a welding professional is best consulted for welding issues.
I would worry more about the SS wire than the Manganese. Especially if it is used more frequently.
Have a good day.
Glad your OK! That woulda drew me up pretty tight.
A mans gotta go when he's gotta go but I'm thankful it wasn't then for you.
Have a great day
I have worn safety glasses (prescription) my entire life. I have never had the "sand in the eye" feeling. I have had them feel a little irritated.
I think UV protection on my glasses has been a major factor in this fact. I have had my cheeks and forehead turn slightly pink but my eyes be fine and still white.
So I too agree that the proper eye protection can eliminate this hazard. Worked side by side on waterwall panel welds with never a burnt eye.
Have a good day
The thing to also remember is that all of the knowledge is available in some format.
I will throw in one more plug for the ole AWS Welding Handbooks ! Its almost all in there .
I reviewed some of the content quite a few years ago. It seemed useful however I had nothing to compare it too. Any information is good information it just depends on how it is best delivered to you.
There is no "best way" to study in my opinion. Just things that work for me, and things that work for you.
I know what you are talking about as far as the "What I want it to do". When I created the database for tracking welds for an orbital welding company, I thought what I charged didn't need to cover all the time since I could sell it to someone else. Then the someone else came along and I realized it was easier to just create another program. All in all, return was probably on the order of $8.00 an hour.
Because so many quality systems require different data to be recorded, its difficult to make an all inclusive program. When they are simple, with few relationships across data, then they can be pretty easy.
Building your own is kinda fun though. I am hoping to get back into it if I ever get back up to speed with something different than "Access" which is still a powerful tool in my opinion.
is a page I wrote about some of my "programming" stuff over the years. There is a link there for one of the Access Databases I wrote a few years ago. Love to hear your thoughts on this "desktop" type program vs the web application.
The link on that page includes the licensed "Runtime" version of MS Access so it is quite large. If you have Access 2007 or later, I can attach the Access file itself. It is less than 1MB.
Have a good day.
Have a good day.
Oh I gotcha on the sharks. I have posted quite a few links here myself. Luckily you guys know I am tender :)
I recently received an email regarding the pricing. Who knows, maybe I need to spruce up my MS Access applications and post a link or two myself :). Mama needs some new shoes!!!!
Have a good night. I mistakenly took a steroid late with a cup of coffee (dark roast) with a handful of Dark Chocolate Covered Cranberries. Who knows, I make make a new internet tonight--or get started on it and leave it unfinished like so many other things :)
Have a good one.
When I was a HS student in welding I never noticed a better or worse book. The interest that was generated in welding kinda caused me to look at all that my teacher had. We used one from Giachino, Weeks, and Brune (I think as I pulled that ooutta my head) but I remember lusting after his "Jeffersons Welding Encyclopedia" and the AWS Welding Handbooks.
I think a the Books from the James F Lincoln Arc Welding Foundation are awesome. Are they "textbooks". Maybe not in the sense of modularized powerpoint presentation cool graphics books of today.
I sincerely believe there are tremendous free resources on the internet that can augment any classroom text to encourage engagement of students interested in welding. And there are not any materials that will change the view of those that don't without the proper encouragement and guidance.
I think the challenge comes from the application of whatever you have and the "complication" results from the presentation. I am not stating that is your problem or that you even have one. I am a babe when it comes to teaching and have a tendancy to "show up and throw up" whenever it comes to welding. So even with something simple, I may "over complicate".
I like the NCCER books I purchased but after looking at the Jeffus/Bower book http://www.cengagebrain.com/shop/search/9781435427884
. The NCCER books have some interesting info too.
Sorry if I didn't help you much. I could probably be asking you for suggestions. Thanks for sharing the trade for 19 years !
Have a good day
Everything still has "glitches" in it Henry. Often times they are the result of one setting, one tool, one file, one program, or other minor detail. The largest software companies in the world continue to release updates for program that they have had ownership of for 20+ years. Praise in my opinion is well warranted. When I look at the overall effectiveness of this forum (An internet App using a database fed by Html forms), then I become impressed with the effectiveness of this type of "program".
A standalone computer, not EVER connected to the internet is extremely stable. But of course if its not working correctly, it will probably need to be "connected" soon. As with all systems of security, there are flaws. That "security" risk could be the possibility of me dropping my laptop off of a scaffold with 3 days of inspection data on it including the images or one single user transposing a id number with a name on his "custom built standalone spreadsheet" and archiving the data, and some other individual trying to figure out whether the Name is wrong for all the related data, or the ID is wrong.
The program is probably hosted on a regular Windows/Linux server and I am pretty sure redundancy is available. But not sure. I do understand your concerns though. One thing that I feel should be required is the ability to export ALL raw data at any time by any admin users with full mapping information to allow the owners of the data to reconstruct any information previously recorded.
I am hoping the $1000.00 setup and 250 annual is for an unlimited (within reason) number of users/projects. If that is a per seat cost, then I'm not a fan either. But people have noo problem putting out 5-10k for autodesk software doing things they could do with opensource or lower end products. If it costs more, it must be better.
I'd love to build a program like this for documenting individual welder training tasks completed under the requirements of a standardized program to allow users to verify individuals stated credentials. Including video or documented "certification". Just a thing in my head. Have a good night Henry.
I went back and made a few entries with Chrome and everything worked fine. Besides a few things, it pretty much does what I did with the Access Application I made. Much less complicated than what I did and obviously some added benefit being a web based database (depending on your views of course).
Some incredible similarities to the access application I built before. It was done for a construction company in the US for use at multiple sites. I am not sure how successful it was but I did do a search for it once and found it posted on someones resume :).
I think its a great idea but have not looked at the pricing. The ability to perform "real" programming is something I sometimes regret not developing to allow for sharing of some of the programs I have built with access.
Everything worked well and I can see it as a useful tool. Maybe a bit more customization for actual individual data importing (Drawing Indexes, Piping indexes, existing welder data, WPS's etc in CSV format)
If individual projects can be added yet separate from others and partial data imported then some some capabilities are increased.
Since there is a wide variation among companies as to how they document data related to welding, importing with field mapping can be nice too.
I think your on to something. Been studying up on php and mysql for a few weeks but by the time I get any good at it, there will be some better way and I will be too long disconnected from actually documenting welding data.
I am working on one now for tracking training activities related to welding training but still in Access/VBA.
Gonna go look at the "pricing" now.
Have a good day and thanks for sharing this. It has been a "dream" to do something like this but really didn't have the skillset.
Probably gonna share the link elsewhere .
Have a good day
I did try to add an annotation to a drawing and it has been saving for 15 minutes. Is this product in use or still under development or are there restrictions on the login accounts?
I have just logged in am pretty impressed just from the aspect of capabilities for a cloud bases resource. I haven't looked at the costs etc but just as a welder/wannabe programmer its pretty cool. Probably not the kind of review to do much for anyone, but its worth looking around for a bit.
I know many are reluctant regarding cloud based "programs/apps" but I think there is some great potential. A thought on cloud based vs desktop, If you don't own the source code, you don't really have "control" over the program. There is a great advantage to your programs travelling with you no matter where you go with a username/password as opposed to being tied to a physical machine.
Thanks and have a nice day.
I'd love to see it. I have built some custom programs in the past for Power and Pharmaceutical projects and would love to see a "commercial" application. I filled out the demo request on the form.
Here is a link to a video showing the one I made. (Remember I'm a welder) but am hoping to learn something besides VB and MS Access. But a long way to go. http://youtu.be/H-i94dkb4KI
There are formulas in AWS Welding Handbook, Volume 1 that calculate "theoretical" angular distortion, transverse shrinkage and other things. I wrote some GWBAsic code many years ago trying to simulate the formulas but gave up based upon my very limited math background. (This was well before Excel, MSDOS and Dual Floppy Drives).
So someone could probably whip up some spreadsheets with all the needed formulas.
I think for consistent clarity no matter where you look through the lens or angle, you can't beat a regular glass lens.
Bang for the buck, that can't be beat. I have used some autohoods and still do but when I really need to see the "guts" of it.
I break out the huntsman 490P with a shade 10 lens.
Autohoods that I have liked for the money are the 39.99 harbor freight blue flame model, the Miller Elite 9400 Titanium, and Hornel Speedglass Air Supplied Hoods. I have used hoods in between those from Arc One, Jackson, and Hobart. As with vehicles, there are tremendous differences between manufacturers and models.
As with many things welding, much is opinion and based upon individual experience. Many things you just gotta check out on your own.
I may have gotten more out of it than they did. But it was all a good time.
Have a great day.
Just wanted to post here about the Merit Badge program that I was fortunate enough to help with last week. I have a longer description on one of my websites talking about what we did but I wanted to share a couple of things with those interested.
1) I'm glad I didn't have to compete with Tim Gary for this job, I would still be in Mississippi.
2) I have only taught Community College Workforce Training courses which is great, but teaching kids or young men and women almost ready to enter the workforce is something I desire.
3) It's a great joy to see someone enjoy doing something that you have enjoyed for 35 years. Even if only for a day!
4) If you want to talk about what we did and would like to talk, my cell number is 660-0162.. You can call or text. The area code is 662
From a Wordpress Page I wrote early this AM. (They gave me steroids for a numb leg, so I was up late and woke up early, hopped up on drugs and welding stuff in my head)
I have been fairly idle in teaching since getting here a few months back and this day really encouraged me. The welding trade has been very good to me for over 35 years. My 1st introduction was in 9th grade shop. Then from the 10th grade on, I was blessed with being able to learn at Kingsbury Vocation Center in Memphis for 3 hours a day. My instructor was Mr. Ed Hemmingway. He was a person that really got my interest in the trade stirred up (that and maybe a little firebug in me). He often challenged me to learn and do more than was required. I ate it up. Point is, do not reduce the value of vocational education because you think everyone MUST go to college. I was able to work for 2x the minimum wage as a 15 year old. 39.5 hours a week. I WAS RICH! But not nearly as rich as I was this day watching these boys weld.
If you enjoy sharing welding, I think this is a great chance. Contact your local Council or Troop.
Have a good day
I like this one the best, or maybe just a touch longer .
Outside diameter not "pipe size" is the variable used. 3/4" Pipe is 1.050 OD.
In my opinion there is no more correlation between welding ability and inspection than there being an air traffic controller and pilot, police officer and judge, president and member of the armed forces, and so many others. Sure, sometimes it helps with perspective and understanding, but is by no means needed. I also feel there is some overlapping knowledge that is needed.
I have come across so many golden arm welders put in positions as QC inspectors that have taken it upon them selves to assure quality by creating there own acceptance criteria with no regard for that referenced in the project specifications . I am not saying that being a welder is a hindrance, but I have seen and heard some things that make me roll my eyes. Things that far exceed those heard from CWI's who just got out of 2 week CWI course.
On the other end, how can a guy make a weld that has never opened up a code book, reviewed a WPS, or even knows what range of qualification he possesses? He can because there are people that are trained to help assure those things happen.
A combination of experience is great, but the skills required are different. They can be developed together. And there are plenty of welders who are great inspectors, but I strongly suggest judging the quality of an inspector based upon his or her ability to weld is no different than judging the ability of a welder based upon his/her ability to read a project specification, apply it as directed, and accurately report his/her findings.
As with many things there are exceptions. I have made some bad welds, I have done some things incorrectly as an inspector. Both jobs are ones I love. I try to even separate the two. When I am hired as a welder, I try not to get into to deciding if my weld is acceptable or not or if someone else s is. I just weld it up, and head on to the next one.
I could tell a story about a 4" crossover line in t he bottom of a recovery boiler that I welded that I am sure the welders that knew I was both a CWI, QC Inspector for the Company, AND part time welding instructor really got a kick out of. I made a terrible mess of it!
Point is, that weld I messed up, had nothing to do with my ability to inspect.
Nor was my ability to weld reflected by the times I visually rejected welds in tube coupons with more than 1/16" reinforcement because I believed it was the right thing to do even though the code allowed up to 5/32" and was my only acceptance criteria.
The jobs are different, the skills are different, we all do good, we all do bad, we all grow.
All of the above is based solely upon my opinion and very limited observation of the welding world. Experiences and thoughts may differ :).
Have a good one.
Welder-Depending Who you ask
Inspector-Depending who you ask
Teacher-Depending who you ask
And many other things-Depending who you ask.
We could always add "....blend smoothly..." and a "....gradual...." just to clarify things a bit.
Have a good day.
If its going to be welded AFTER its bolted up, then the bolts/studs can be an issue but t hat shouldn't be the way its done.
Very "Non-Textbook" electrode travel angles are used in real life. An example is water wall panels on a boiler. Extreme "push" or "pull" angles are used at at the membrane or tangent section. the same thing can be done on pipe. As with many things welding related, its not "by the book" but its been working for years.
If you gotta think about how close you CAN get it, you probably need to look at it in real life and see how its gonna be to weld. Do all you can to make the joint weldable. If its as easy as you can get it, then it is what it is.
The standard is sometimes mentioned in the field its the DU 1.1 "Specification for those who didn't have a clue.". As with many welding terms, the slang version is "I'd like to meet the idiot that drew this"
Have a good one.
I checked out the RSS feed apps and the one I downloaded worked fine. Most will let you click on a feed and view it in your browser. If your browser keeps you logged in, you should be able to post .
I did this last week. I'm a better welder than I am a Camera man, Cue Card holder, and speaker. ...and I ain't all that good at welding. http://youtu.be/KXQmWhFmQ74
I dont think so but there is or was an RSS feed.
Oh yea. The TV will be put to use. I'm a web showing, PowerPoint using kinda guy.
The other equipment consists of small tabletop type training aids for mechanical maintenance. There are some valve cutouts and similar components, but more for the millwright and mechanical maint. trades. Good stuff cause t hey have had more classes than I have. Industry here has taken a pretty good interest in the maintenance training offerings for mechanical and electrical.
I do the Weld Tests with quicker acting acids . But I would not restrict someone from doing this should the code in question not specify what should be done.
BUT AWS D1.1-2010 says "A suitable Solution shall be used for etching to give a clear definition of the weld. "
Other codes are a bit more specific but even those in Sec IX are "Suggested" but do require a visible heat affected zone.
I have seen manufacturers use a torch and heat tint.
One thought though on the level of detail needed, typically the only thing being looked at is penetration, fusion, and discontinuities of a size that can be seen by the naked eye. (1/32" in the case of Section IX for Performance)
Have a good one.
The 300K didn't all go to welding. Tim was a key player in getting everything selected and did a good job. We have the following.
5 XMT 350Mpa Power Sources
3 Invision 352Mpa Power SOurces
8 S74Mpa Wire Feeders
2 Syncrowave 250's
1 Realweld Trainer
10 Miller Arcstation Tables
1 Doall 1417 Vertical Bandsaw
1 Scotchman 50 Ton Ironworker
1 Lincoln/Torchmate 4x4 plasma table with Hypertherm Powermax 65
1 Sawyer Guided Bend Tester
10 Miller Filtair Fume Extractors
1 Oxy Acet Cart w/Victor Equipment
1 EH Wachs Electric Pipe Beveler
Ingersoll Rand Air Compressor
and associated accessories.
In addition to the welding equipment, there was a considerable amount of training aids and assessment devices purchased for mechanical, pneumatic, electrical, and PLC's.
There are also two classroom equipped with Large Screen TV's and support equipment.
I am looking forward to getting started. I am hoping to get things going soon.
Have a good day
Many may already know this and many may not have any issues with handling acid. I would think HS instructors may be limited on what they can do when it comes to etching.
Regular White Vinegar from the grocery store will do a pretty decent job but itt may take a day or so. Attached are some pics of a few pieces that were etched this way.
Sound like a good deal for them. On that Victor Torch, I have a small one with an "Ergonomic" handle. It too leaked at the tip. Brand new torch, brand new tip.
Have a good day.
I offered to wear my "Sunday gotomeetin" overalls but I was told that was not a good idea.
I haven't actually done much yet other than some consulting. My sales skills may need some work. It may be hard to believe, but I talk too much :)
I am looking forward to starting a few projects. I have most of the quality system together for testing welders (ATF and NON-ATF will all be done with the guidelines of AWS B5.4).
The open enrollment classes have not caught on yet. I guess I should quit telling people that a 20.00 per hour job with 4 hours of training is unlikely!
Have a good one
I am not sure where it came from. It was changed once before I even know what it was. I was shooting for the "Grand Pooh-bah of Welding Stuff" but was shot down.
I also am not allowed to publicly refer to the building with the word "center", so there is something to a name.
Cool. Thanks !!!!! Now I have to get that picture at the post office taken down!
If you are in a service environment that requires heat tint and oxidation to be removed, and you do so by chemical means you have t o consider the ability to remove the pickling agent after you are done (faying surfaces that cannot be accessed or internal surfaces that may allow collection.)
You would also normally follow up with a passivation process that restores the chromium oxide layer.
"Sugar" or root oxidation is not a problem in many cases but that is a decision for engineers to put in the specs and not a matter for the lowly inspector. Many codes for piping do not address this "condition" as a defect. As with everything, the service conditions evaluated by engineering professionals should be the deciding factor.
There are documented research studies that show the mechanical properties of welds made without purge being equal to or bettter than some welds made without purge. http://www.aws.org/wj/supplement/WJ_2014_04_s124.pdf
Here is a statement from an abstract of an EPRI article at http://www.epri.com/abstracts/Pages/ProductAbstract.aspx?ProductId=000000000001009717 Moderate to severe surface oxidation (generically referred to as "sugaring") is thought to degrade the mechanical and corrosion properties of SS weldments. This study involved an analysis of surface oxidation on stainless steel weldments.
Test results showed that surface roughness due to severe sugaring could potentially compromise mechanical properties and crack initiation sites if subsurface defects are created. Basic mechanical data (bends, tensile and hardness measurements) showed little affect due to sugaring. Corrosion tests (ASTM Practice A, C and E) also showed no detrimental affects produced by the various degrees of sugaring.
I am not saying sugar is "OK" just that sometimes it just may not matter. Of course its hard to call over all my welding buddies and impress em with the golden wedding band on the inside of my coupon.
Many a superheater pendants have been welded in with no purge and RT.
When I think of "High Purity" the term "paint" never comes to mind however that is based upon a limited exposure to many industries.
Now on to read the rest of the responses :)
I have used that before.
Another place the "developer" method comes in handy is leak tests on a gas tight component that is verified by liquid "leak test".
I did some 3rd party inspection where I was to inspect for "any evidence" of leakage on duct work and air pollution control equipment. On joints with multiple faying surfaces, it would take a considerable amount of time to both wait for the leak and also get back up in a lift to look (the procedure that was approved did not account for joint configurations that may take a day or so for capillary action to do its thing. Spraying the joints or at least starts/stop and corners would greatly help things become visible faster. On some of the above cases, I never saw any liquid but actually discovered cracks that became evident from shop "dust" gathering at the crack ever so faintly.
In addition, with the liquid leak test, you could wipe it off, spray it again, and see the exact location of the opening.
Have a nice day
I am not sure what "accredited" means in relationship to welding education. (Other than SENSE and an AWS ATF)
Schools may be "accredited" by various organizations that may no nothing about welding.
A school that has authorization to display the SENSE accreditation may just be able to support Level I (Entry Welders).
I would strongly suggest talking to the instructor. 2 Weeks of Tig (80 Hours I imagine) may work wonders for you. Then again, it may take a little more time depending on your goals and existing experience.
Have a good day.
Those are incredible. Inspiration ! We just had a "Ribbon Cutting" today where I teach. Right now we are still in the "booth" stage!
Thats a great thing you are doing with your students !
Have a great day .
I appreciate your response. I have only been to a couple of the local meetings so kinda getting my feet wet there. Though I do probably speak up a little more freely than someone who is "new" should. I have yet to get too deeply involved with industry here but my point about organizing is more of an idea I had for a larger scale. The "Instructors Institute" section of the forum really got my attention when it was put in the forum but I really never did find out what it was about.
The local scene where I am is still being developed on my side and I will keep your information in my mind as I move forward here.
Have a great day and thanks so much for your information. I may have more to post about the subject.
I would think there is more usable data 1000 year old pieces of paper than there are 40 hear old magnetic media. :)
