So, what is it that you find so threatening, an opposing view?
I didn't disagree that welding experience is beneficial, it just that being a competent welding inspector takes more than being a competent welder. The ability to weld is just one of many factors that can contribute to successful inspection and a successful career as an inspector.
Even if welding experience was mandatory, few of us have experience with all the different welding processes that are used to produce welds. What welding experience should be made mandatory, SMAW, FCAW, GMAW, GTAW, LBW, EBW, ESW? Does the inspector have to demonstrate proficiency on structural plate or would you demand they pass an open root 6GR test? What base metal should be mandatory when taking the qualification test?
Since the welding inspector is often checking fabrication that involves layout, dimensional checks, structural steel framing, titanium structures for aerospace, petrochemical, or the paper industry, the inspector may also be called upon to inspect bridges, ships, railroad rolling stock, etc., does that mean the CWI candidate should show competence in each industrial sector as a condition for certification?
Should the Certification Committee require the CWI candidate to demonstrate competence in using several codes or is the system in place sufficient to determine one has the skill set needed to navigate a code to find specific information?
Whereas the welding inspector is required to monitor NDT, should the CWI candidate be required to demonstrate proficiency in each NDT method used to evaluate welds?
The welding inspector needs to have a basic understanding of stress, strain, material properties, concepts such as tension compression, torsion, bending stresses, stress intensification caused by geometric features, i.e., welded lugs welded to tension members, undercut transverse to the primary tensile stress, etc. Should the Certification Committee require each candidate posses an engineering degree?
My position is the CWI examination requires the candidate to demonstrate basic competence in one's ability to evaluate a weld in accordance with a standard. The specialization, if one decides to go down that road, comes after obtaining the basic credential. Expanding one's competence is something many CWIs do once they have earned the CWI credential. Granted, some CWIs are perfectly satisfied and earn a good living with nothing more than their hard earned CWI credential. The decision to obtain additional training, additional credentials, or to maintain the status quo is left to the individual CWI.
I like the CWI program and I believe the new Part B is an improvement over the old Part B examination. The program has evolved since the 1970's. At one time there was no practical hands on examination. It was a short coming that was address in the early 1980's. Make your case to the Certification Committee if you really believe experience as a welder is essential to being a competent visual welding inspector. I believe you can attend a certification meeting, present your case, and you can do so without anyone on the committee telling you to "pull you head out of your rectum."

It's ironic. The same people who say the exams are difficult because they have no value Unless they prove you are an expert... Are the same guys who tell new CWI's that they are now just beginning.
Only one of those statements is validated by testing.
I was doing NDT and inspection on Boeing, Pratt, Allison, Rolls turbines and on the D17 committee long before I bothered to earn my CWI credential... CWI ment zero in the aerospace world until the advent of SpaceX, and they are as close to clueless as you can be.
Having said that.... The scope of duty a CWI might find himself in is VAST... But the society has shared the Part B freely up till now... That gents is the elephant in the room.
They shared it before (for free) and they won't now, with no explanation... That is unethical, and the AWS needs to do something about it.

Taking a test with a fake code book, a top secret book of exhibits and using fake weld specimins that have imaginary hypothetical dimensions is hard enough without having to decipher AWS trick questions in less than ample time. Seems like another way for AWS to get into our pockets. Did I mention AWS has some of the worst customer service I have dealt with. I ordered a book and ended up cancelling the order after 2 1/2 months wait. Good thing it wasn't mandatory and one was provided for me. Would have liked to read it beforehand anyway.
Al, we understand what an inspector does. And hypothetically speaking , if there was a weld test, it should be applicable to the code you were testing in. Glad your happy with your new part B.
To your first point, I think that's where the issue with the process is.
QC-1
4.2 The SCWI and CWI shall be able to perform inspections or to verify that the work inspected and records maintained, conform to the requirements of the applicable standards and perform all WI duties listed in AWS B5.1, Specification for the Qualification of Welding Inspectors.
B5.1 Table 1 Welding Inspection Capabilities (only few listed below)
Procedure Qualification
(1) verify welding equipment appropriateness
(2) verify edge preparation compliance
(3) verify joint geometry compliance
(4) witness procedure qualification
(5) verify welding procedure qualification compliance
(6) review and approve welding procedures
Performance Qualification
(1) witness welder performance qualification
(2) verify welder qualification compliance
(3) verify welder qualification records compliance
(4) request welder performance re-qualification
It's shouldn't be the employers responsibility to decipher who has the skills, knowledge and ability from the CWI applicants. The certification process tells these managers that each individual shall be able to perform these duties. So on one hand, from whats listed, the AWS is saying that a CWI (newly minted or not) is above 'beginner level'. However, from the experience posted of many on this forum, that's not reality. A freshly minted CWI is typically in the beginning stages of learning and applying these skill-sets. The testing process does not verify the listed capabilities sufficiently enough to make these claims. I'm pretty sure the CWI founding fathers had a different vision than what is being delivered today. Although you wouldn't get that from reading any articles, where there is a lot of chest thumping on how great the test and product is. They're really in the process of training for a test. Anyone involved with developing curriculum's, objectives and testing can see the holes. Throw in the code of ethics, how many CWI's with little experience in a certain area are going to turn down 500 to 1000 a day because they don't have enough knowledge in that area? More than likely only the experienced CWI's will turn those opportunities down. Experience prerequisites - who monitors that? Apparently if you work at a company where they weld something, if you were a secretary filling the qual papers, good to go. So what is it? Is a new CWI an experienced, knowledgeable inspector or a beginner? I'm not sure I would include reviewing and approving WPS's in a beginners list of capabilities. I guess the definition of beginner and what quantifies it would need to be established.
GREAT POST!
Honestly, I think the prerequisites, exams and body of knowledge required for the AWS CWI are excellent. So yes, sometimes I'm amazed with the various levels of competency encountered in the real world. But it's hard to blame the AWS for that... (I have lots of heartburn with AWS, but not here)
Employers hurt themselves a lot of the time by not having subject matter experts placed as decision makers in inspection and process. If the right person is presiding at an interview, a 5 minute conversation with a prospective inspector will say much more than certs, diplomas and pedigree.
I did a project for Bechtel once upon a time. They really had the right people asking the tough questions. I couldn't have been more impressed with their process of "people placement" and subject matter experts involved as gatekeepers. They had HR people at the table as you would expect a mammoth organization would, but they were silent.
I agree you can't blame the AWS for this issue. But unfortunately, having the right SME's in place is not going to happen. Having the right management personnel approve and sign the applicants application verifying experience, training and capability isn't going to happen. In many cases they don't know what or how to measure and verify these credentials. After all it's only welding (that's what people that didn't want to go to school do. Well, welding and mechanic). Since the AWS is the certifying body, there name is on all of our stamps, they ultimately are responsible for the product they are certifying. To ensure every CWI is compliant to QC-1 and B5.1 would be a tremendous investment. The problem lies with employers and the individuals themselves either not completely understanding what's required of them or trying to short-cut the process for various reasons. It's a self-policing situation. There is no way the AWS can invest enough to police everyone. Personal accountability. If someone doesn't have a grasp of the requirements, get a grasp first then pursue the CWI, not the other way around.
Good comments jarsanb.
AWS has done a pretty good job of making the CWI exam difficult enough to help weed out applicants who are not qualified to perform the job.
I think AWS should take steps against short circuiting the process by declaring proprietary rights and forcing all these "learn how to pass the test" schools to cease and desist.

Lawrence,
as everyone knows
I have worked with Bechtel ( and Fluor)
and have a very low opinion of them
but everyone knows how I feel about
engineers and inspectors
a little late on the post
just my thoughts
sincerely,
Kent
