You've used that procedure previously on 10 well heads. So, we may safely assume it's a good procedure, although it's not qualified. Your present customer insists that he wants a qualified welder to do it. Now, if the procedure isn't qualified, there's no welder who is qualified to make it. So, what you've got to do is to qualify the procedure AND the welder at the same time.
Simple: the welder will weld the well heads following the mentioned procedure, and the specimens will be tested according to the applicable standard (ASME IX?). If the specimens are approved, both the procedure AND the welder will be approved.
If the specimens aren't approved, there are two possibilities:
1. The procedure is no good.
2. The welder is no good.
As we don't know which one of them is true, ANOTHER welder will re-weld the well heads according to the said procedure and the tests will be repeated. There are two possibilities:
1. The tests are approved. In this case, it's assumed that the first welder was no good and the procedure AND the second welder are qualified.
2. The test aren't approved. In this case, it's assumed that the procedure was no good and neither the procedure nor the second welder are qualified (no welder can be qualified to follow a procedure that's no good).

You Qualify a welder to a process and the restrictions of the actual test, position, material thickness,.... I don't have the codes for the welds you are writing of. But there should be Welder qualification tests in them. Hope this helps more than it hurts
