Re: [MW:7869] WQT- Number of Welders Issue

I understand that, it has not been allowed to weld by 2 welders on single pipe as pr ASME latest revision.

 

I don't have latest edition, but you can find recent article in Welding Journal (Aug 2010) discuss about this issue.

Dear All,

Design Code – ASME B31.3

Welding Code – ASME BPV SEC IX

Can I use multiple welders in a single test coupon for WQT.ie, two welders one half with two process (6 o'clock to 12 o'clock) and other half (6 o'clock to 12 o'clock) another two welder with two process(Suppose all welders are crossing the minimum 6"(150 mm) length)?

Is there any clause insisting that one welder has to weld the entire pipe circumference irrespective of diameter?

 

Regards,

 

Limesh
