First of all, what does your job description or contract detail regarding what your responsibilities are. The reason I ask this is before you decide to do anything, you must know your scope of work that's required of you in writing as Thirdeye asks otherwise, you're not CYA or B!!! Meaning, Covering Your Ass or if you prefer, Buttocks... This is one of the reasons that Bill suggested for you to hear what a labor lawyer has to say about this situation you're in... You've been given some excellent advice from the rest of the replies so, at the risk of being repetitive with my advice, I'll just say that you NEED to accept the fact that your going to be very busy writing, logging everything to back up your observations and your report, Rewriting your training materials, manuals etc., that's if they decide to accept your recommendations because, after all -you are training and consulting are'nt you? Their people are the ones signing off on the work, correct?
DO NOT Sign off on any of the work that's not in compliance to AWS D1.1 - Integrity is the KEY HERE!!!
Make REAL sure you're not overlooking any details that may enable the company to justify their actual welding and inspection practices that may fall within the parameters listed within their or is it the customer's welding procedure specifications by making darn sure that there are no exceptions that allow such practices within AWS D1.1 itself and if they're not following what's required of them based on what is written in their or the customer's WPS's then, NCR them to DEATH - if this is part of your job description or written in your contract!!! Stand your ground!!!MAKE SOME NOISE!!!
After all, would you really want this in your conscience??? Gnawing away with ever increasing guilt especially if as Tim said it best, Lives and Limbs may be at risk???
If this is the case then, If they are not welding or inspecting the work to AWS D1.1 or whatever code or standard the customer requests then, there is a procedure to report not only to the company or customer in question but, also to the AWS that these so called inspectors are NOT complying to their CWI requirements if they are CWI's...
If you are an AWS CWI, then it is your duty to report their lack of compliance provided that you've informed them, documented to them that they must take corrective actions in order to become in compliance and, if they ignore your consultation, inform this to the governing bodies within the AWS certification department that handles this type of situation!!! Before you do this, make sure you've double checked yourself and all of your findings. Make sure you can prove it!!!
Get in touch with Kip Mankenburg (I hope I spelled his last name right) or anyone else in the AWS certification department because, they may be able to guide you through your present situation where the end result will be benificial to all parties including yourself!
I'll be praying for you in the hopes that everything will work out for the best!!!
