Dear All,

Greetings,

We are preparing a WPS with dissimilar base metal A240 gr. 321H and A516 gr. 70, Instead of using this two material specification. Can we use a312 gr. 321H and A106 gr.C. for PQR.
Thank you.

It would be handy to know according to which astandard you're working.

Wow, you want to weld a coupon consisting of pipe instead of a coupon consisting of plate with backing? Congratulations, you have brass ones my friend.
