Hello Everybody,

We welded test piece in position 5G ( 2" pipe, SA312TP304L ). That we wrote in to PQR. What shall I write to the WPS? Acc. to QW-461.9 positions qualified are F,V,O. But it is valid only for welders qualification, isn`t it?

Thank you for your help.

All positions. Per code any one position qualifies the procedure for all the positions. QW-203. That was why people rarely use pipe to do the weld coupon.

QW-203 is clear - Thank you! As we weld more acc. to European standard I still fight with the differences. Anyway, we used pipe to qualify welder too.

To qualify welder's full qulification, using pipe is a must. WPS is different.
