[MW:12687] Backing Weld

Dear Experts,

Please share your experience

PQR is qualified for GTAW+SMAW Process for P1 material but because of ovality problem in the pipe it is required sometime to go for backing weld with GTAW process.

What will be the effect of backing weld on mechanical and chemical properties?

Client is not allowing for the backing weld. Is it necessary that PQR is to be qualified with backing weld?

If code is supporting for the Backing weld if PQR is not qualified for backing weld please send the reference for the same.

 

Thanks & Regards,

Azam
