Dear All,

 

I have a situation in which I need to qualify a WPS with 40mm root gap and 10mm base metal,

 

But the client is not ready to allow us to conduct the PQR, he need a technical clarification before we conduct PQR,

 

Is it allowed to weld 40 mm root gap with backing plate as per AWS D1.1, please help me. 

 

Regards,

Arun Padman Manayil
