[MW:13083] Preheating temperature of 2nd process when use two welding process in one single joint (GTAW+SMAW)
| Dear Experts, When we are using two process (GTAW + SMAW) on pipe test coupon of a PQR, Root run & hot is done with GTAW process, immediately after hot pass we have started SMAW process, Prior to start of SMAW process, temperature of coupon noted was 95 deg C My question is whether this 95deg C will be considered as preheating temperature for SMAW process Kindly advise in the light ASME Codes Thanks in advance Mhaskar Aly UAE | ||
