So lets say that Bob comes into the shop and he welds a coupon for a certain size pipe. We send that out to a lab and comes back acceptable. This information lets us complete the WPS and PQR formulation. So lets say the WPS and PQR are completed.
Now lets say Steve is a brand new employee and he is assigned to a job to weld the exact assembly as Bob. To list him as being allowed to weld that material, process, position, etc, does he have to make a coupon that would conform to the WPS and we send that out to the lab for the same testing?
We have a bunch of Hobart books that were collected and one of them states for performance qualification "Welders are required to demonstrate their skills by using prequalified or qualified procedures to prepare sample welds. The sample welds are tested and evaluated according to the specified quality and guidelines for the job. The guidelines should be a published code or company standard?
So with this example, WPS and PQR are qualified for ASME IX. Can our CWI do visual testing on Steve's coupon and cut it apart to do our own bend test (representative of ASME but not exactly)? If work believes that Steve's coupon would satisfy the requirement for a good weld, is Steve good to go?
