Read the contract, if the welding is done to any code, API, ASME, BS, DIN, AWS, IBC etc. then weldors and their procedures must be checked and no I would not say violation of your CWI, I would say CYA. Are you to check the welding or just say yup it's there? I see weldors apply for a job every day, they all say they can weld and a actually a few can. That is why we test them and test them and test them................. I've done over 40 just this year.

The scope of work included in the contract documents is exactly what your client requires.  In many cases the fabricator has submitted their procedures to client/owner/end user for review and approval by a welding engineer long before the project gets to the construction stage.  Many of the ITP (inspection test plans) I receive only require verification of documents supporting welder qualification.  Of course, you will have access to WPS or PQR's for your personal review so you can monitor compliance.

Start by reviewing AWS QC1. Then, if you are inspecting to AWS D1.1/D1.1M 2006, and I say 2006 due to the fact that even though it is 2008, the 2008 revision has yet to be released by AWS, refer to section 6 Inspection. Specifically 6.1.5 / 6.1.6 / and 6.1.7. By the way, how long have you been AWS CWI? Always remember as a AWS CWI that there are three more letters, CYA Cover your ***!

You should probably avoid posting the same question in multiple locations.  It gets confusing.
