Section IX - welder qualifications MIN allowable to wall thickness
Section IX - welder qualifications MIN allowable to wall thickness
(OP)
I have been reviewing some welder qualifications for a small bore 2" piping job sch 80 , the wall thickness is .218 .. The welder "tickets" shows qualification of .250 - max from 1" OD and up . My question is does he qualify to weld on this material as it is thinner than the material he qualified on ? I have heard conflicting reports that there is no minimum deposit thickness qualifications . I am struggleing to find a clear answer in ASME IX. any help or clarity would be appreciated.
