I don't see where he's getting upset at all. Just posting a response to those that he received.
Well I guess we see and read stuff differently then because I do. ;)

Henry,
You understated about this forum.
I have been on a few forums on the web, and quite a few job sites, more job sites than I care to say. (I would then look old.)
And I thought I was pretty sharp, so did other people they would ask my opinion and advice.
I got on here and as far as being a sharp knife in this drawer, I am not even a butter knife, I feel like a plastic spork.
Thank you for your time and consideration.
Sincerely,
Kent
I can understand weldstudents frustration . He asked a question about a certification test and got answers about production. There is a world of difference between certification and production.
Levi.
The simple reason is that it is their test. They wish to see if the applicate can pass the test they set up, to their standards.
Now the AWS, ASME, and API can have someone come on here and give very specific reasons why their welding test are done the way they are.
I do not even come close to speaking for them. But again it is their test and their certifications.
And if you really want to preheat on a welding test just have some patience and wait till August and go to Las Vegas tack your plates up and set them in the direct sun for 3 hours when it is 105+, They will preheat real good.
Hope this helps
Thank you for your time and consideration.
Sincerely,
Kent
I was thinking that might be the reason("simlpy to aid in the wet-in and penetration on the root"). The inspector may have thought you needed to preheat to pass when asked that question. If I was testing you in my shop for a job, I'd wonder why as well, raises some doubt in your abilities.....not saying you can't, don't get all fired up but you see the point I'm trying to make? When I weld them out with no preheat, why does this guy want to preheat when it's not needed. See what I mean? When you go to test, I, the inspector or whoever don't know you from adam, so it makes a persons mind spiral when that is asked into things like, "is this guy gonna want to preheat everything?". When you asked and he said no, I suppose he would have been the best person to ask. But then again, questioning the inspector's probably not a good idea! LoL!! Unless you were extremely tactful about how you asked it to where it didn't sound like you were questioning his authority or whatever but just being curious. I think I talked to one guy that said that you were allowed so many degrees tilt on your 3g, not making it a true straight up weld. They would lean it back because you were allowed so many degrees, which means it's legal can be done no questions asked. I set mine all straight up, figured I can't go out and tilt a building when I get out on a job so I better learn to do it the right way.
I guess some don't want to see "allowable techniques to assist" because they want to see you weld it out like it's laid out to see if you can actually do it. I've been around a bunch of students and have them ask questions about ways they can use "techniques to assist" and have told them like I was told/taught, learn it the right way first, then the tricks of the trade will come to you when you get the piece of paper and get out in the field. I think one trick was walking the cup in tig. Some don't want you to do it to see if you can weld it without the "technique", see what I mean? This is what I learned from welders who have been doing it for over 40 years, another at 35 years and another at about 20 years. Basically it was don't cheat yourself while your learning. Sounds like your putting in the effort though, getting there early to class. I've seen guys waste day after day sitting in the classroom talking, outside smoking and joking and not burn 1 rod all day long. Good luck and keep at it Levi.
It would be my opinion that considering the central part of a GTAW arc plasma is upwards of 10,000 deg, and that the puddle is, I don't know, maybe 2500 deg, If a 200deg preheat makes a difference I doubt you could even notice.
