Materials & Welding

Dear Friend, Purpose of post heat is to DIFFUSE hydrogen after welding , for this purpose we hold our joint at 93-80 degree for 1 hour after completion of welding.  PWHT always Performed below Lower Transformation Temperature, PWHT and Post Heat is different things.

Hi, As per B801 clause ''provisions apply'' does not seems to be your case as 823.2  / B823.2 both para exists simaltaneously, also as per below interpretation 13-7-Q4, sour gas service can be qualified as per IX of ASME for procedure, to be noted again it is very clearly written ''if a weld procedure for sour gas service is qualified under asme IX'' where as when we come B821.4 it stipulates weld acceptance as ASME IX  which is qualification too?  anyhow as per this interpretation when it is ensured procedure qualified under IX then you can go also for performance and snatch your qw-304 alternatives regardless of B823.2. Note: File 03-154,  interpretation 13-7-Q4  is just reference for the subject and i would like to know more experts interpretations. Thanks.
