Is this correct or do I only have to run a procedure 2% CrMo to A106. The material is P22 I think to P11 Carbon.
I am using Union 1 Crmo 910 GTAW and the SMAW has slipped my mind at the moment.

To qualify this procedure, all you really need is one weld coupon consisting of Grade 22 material (ASME P-No 5A) welded to SA 106 carbon steel (ASME P-No 1). You have several choices for filler metal - you can use carbon steel E 7018), or you can use an E 8018 B2 (1.25% Cr- 1/2 % Mo) or you can use E9018 B3 (2.25% Cr-1% Mo).
Normally, when you are welding low alloy steels to carbon steel that have greater than 3% Cr in difference, this would be more of a true dissimilar metal weld that would require possible use of a safe end that contains a chromium content in between the high and low alloy materials or careful selection of filler metal to reduce carbon migration of the steel containing lower chromium content.

Please advise me about your service condition and application. Why do not you use flange connection in your case?
