RE: Dissimilar of Materials
I would recommend welding the A 106 to A 335 Grade P22 transition piece and weld using the GTAW root with SMAW fill ER80S B2/E8018 B2. Once this is completed and PWHT, if required, I would weld the SA 335 Grade P22 piece with a 5% Cr filler metal to the Grade 91 pipe material.
