Re: [MW:29392] Qualification of 2 welders in one Test Piece (Pipe 12" inch)

Sir,

As per the code is YES. 

But as per the ASME IX  interpretation, the welder should complete one full circumference weld. 

I remember when we doing the qualification, our client insist to do full circumference weld w.r.t to this class.

I am searching for the interpretation No and clause. I will send to you.

If the Position of the WQT is 6 G , that one Test coupon (12 " inch ) - Can qualify Two welders or Not ? hence the total length welded by the two welders in parallel

 will be radio graphed.

It depends also on the positions you want to qualify. Pls read the Code carefully, to check if they have to weld an entire circumference

Dear Sir

I am inquire about the Welders qualification test as Per ASME IX - QW-302 & QW-304

If I make WQT for qualification of (2) welders welding together in one test Pipe 12 " inch

hence the total circumference of Pipe 12 " inch = 957 mm so, Each welder will weld more than 150 mm as required by ASME IX And all the Pipe Circumference welded by each welder will be radio graphed.

Is that Acceptable is or not to qualify 2 welders in one test piece (Pipe 12" inch)?

Kindly reply on my inquiry.
