Can a pre-qualified PQR that was qualified using SA516-Gr 70 material with P1-Group 2 to P1-Group 2 support a written WPS for the welding of API 5L-X65 (S1-G2)pipe to SA106B (P1-G1)pipe. Per ASME Code ruling, is the above acceptable? Can the same WPS qualify welding of ASTM A694-F65 to SA106B material ? Professional advise appreciated.
