Re: [MW:13130] Preheating temperature of 2nd process when use two welding process in one single joint (GTAW+SMAW)

Yes you can consider it is as preheat and check with your WPS for preheat
requirements. For example if the preheat is 120 degree then increase
temperature to 120 deg and start weld.

Dear Experts,

When we are using two process (GTAW + SMAW) on pipe test coupon of a PQR,Root
run & hot is done withGTAWprocess, immediately after hot passwe 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

Thanksin advance
