If the operating temperature is high , I would seriously consider ERNiCr-3 (Alloy 82) rather than trying to solve the problem by moving from ER310 → ER309LMo. Nickel-alloy fillers are frequently used for difficult dissimilar-metal joints because they tolerate the chemistry gradient/dilution between different alloys and can provide a more forgiving weld-metal structure. This is especially relevant if PWHT or substantial thermal cycling is involved. Regards, Ashish Ranjan Save a tree...Please consider your environmental responsibility.

Good Afternoon, According to EN 9606-1,  Parent material groups are "Non-Essential", But need to record in the Welder Certificate as per Code Requirement. There is a statement " Welding with a filler material in one group qualifies the welder for welding with all other filler materials within the same group, as well as other groups, listed in Table 3, and welding on parent materials from groups 1 to 11".(@ Page 10). 1.My question is Group 1 Cover all Group 1 to 11?

Dear Sirs, Good day. As per API 1104, we are going to run PQRs soon; So, Please give your suggestion and comments for welding the following API 5L series of pipes with the selected Class of welding rods & Fillers : First, let me know if the selected AWS class are OK to proceed or not ? 1) API 5L Gr. X42 :  GTAW : AWS Class 5.18 ER70S-6 +  FCAW : AWS 5.20 E71T-1C 2) API 5L Gr. X65 : GTAW : AWS 5.28 ER80S-Ni1 + SMAW : AWS 5.5 E8018-C3   3) API 5L X70 :  GT : AWS 5.28 ER80S-Ni1 + SMAW : AWS 5.5 E9018M (OR) FCAW : AWS 5.29 E91T1-K2C  Also recommend me for welding parameters such as Amps, Volts, Gases, Preheat, Post Heat, Interpass Temps with site links to make these PQRs successful.
