Hey All,
Quick question, I'm trying to certify some new hires on our machines/processes. Before I joined up, new operators were instructed to weld two specific plates together using a documented WPS, (one that has all the supporting PQR data)
However, Figure 4.22 Test Plate for Unlimited Thickness - Welding Operator Qualification shows a much different depiction of what is going on than what has been done. Specifically previous operators were qualified welding two Double V groove plates together in a butt joint configuration. (Extensive testing would follow). However, 4.24.2.1 states, "For other than EGW, ESW, and Plug Welds. The qualification test plate for a welding operator not using EGW or ESW or plug welding shall conform to groove and fillet welding in material of unlimited thickness for the process and position tested."
Does this mean, because our Double V groove is not the same as Figure 4.22, none of the welders in house are qualified?
Thoughts? Thanks!
I like Brent's response.
If the governing code is D1.1, the required tests are specified for the welder, welding operator, and tack welder. Again, the required tests are depicted and they are listed in Part 4 of clause 4. No hidden clauses or foot notes. It is all spelled out for the reader.
If the contractor wants to administer additional tests, it is their prerogative to do so. The welder can be required to hang by one leg while welding upside down just to demonstrate the ability to perform welds that will be encountered in production. Want the welder to weld with one eye? Duct tape the one eye you don't want the welder to use. Want the welder to demonstrate the ability to use a grinder, carbon arc gouge, use an ice pick to perform interpass cleaning? You free to do so after the required tests have been taken and passed.
Best regards - Al
