Dear Members,
Please provide a clarification on the following query.
One PQR is qualified with GTAW+SMAW, ER 70S-3+E7018-1 and impact tested at-46.
Impact testing is required for the job at -29 Deg.C. Can I use ER70S-2 instead of ER70S-3 ?.
As per ASME Sec.II C, ER 70S-3 supports up to -20 Deg C & ER 70S-2 Supports up to -30 Deg.C.
Is QW 404.12 applicable in this change?.
Thanks & Regards
Muhammed Ibrahim PK
