Dear Friends
I've have 2 separate WPS/PQR-01 qualified using SMAW & FCAWx EH36 X EH36 x 25.4mm THK. plate with -40 Degree Celcius.Based on Table 4.6#2-Min. Thk qualified is 16mm . Is there anyway i can waive form this requirement and use the same WPS/PQR-01 weld to DH36( -20 degree celicius ) material with 10mm thk? Weld Process either SMAW/FCAW.
Is there anywhere in the code allow such deviation
Appreciate any advise/guidance
