Dear Experts,
Kindly suggest a solution on case:
We need to make PQR of below joints and supplier is proposing a electrode mention below with reference to cost impact. Is it acceptable or not?
Welding joint 1 : A 537 Cl2 to A537 Cl2
Proposers electrode from supplier is E9018-M instead of E8018-G. Electrode E9018-M cost is lower than E8018-G as per supplier feedback.
Welding joint 2 : A537Cl2 to P355NH
Proposed electrode is E7018.
Impact requirement of both joint is -20 degree 32 Joule minimum and 40 Average.
Regards,
Jignesh
