Hi there,
I'm new to this forum. Has anybody perform a procedure qualifications using SA 335, P91 to SA 106 Gr B before? I'd received feedback from the past to use pup piece of P22 to P91. P91 to P1 is not suitable to be welded for the reason due to vast difference of chemical analysis/properties of the two different base metal.
However, I would be glad to hear if anybody has done this procedure before.
Regards,
Lee..
