When multi-qualifying a welder to API-1104. If a welder takes both the butt (horizontal) / branch (fixed) tests on 12" (X52), does this qualify him for all grades? If the pipe on the project is X65, is he qualified?
Reason I am asking is 5.4.2.2 C
C) for materials with a SMYS greater than or equal to that of the material specified as API 5L Grade X65, each grade shall receive a separate qualification test. Is this referring to the Procedure Qualification Test or Welder Qualification Test?
