Re: [MW:6844] PQR according to ASME section IX

Dear Mr.Herman

Please refer QW-211 ( base metal)in Article II of welding procedure qualifications ASME Sec IX, which clearly mentions that qualification in plate also qualifies for pipe welding and vice versa.

>Dear All,



I'm preparing some WPS documents for procedure qualifications and

production documentation according to ASME section IX. In my opinion a

procedure qualification made in plate is also valid for pipes

according to ASME section IX as long as the essential variables are in

range of the specification, but can anyone tell me the paragraph where

this is mentioned in the rules? Welding process is PAW but this in my

opinion is also not an essential variable for diameter qualification.



Thanks in advance.
