Mechanical test for Welder qualification

[Muhammed Ibrahim PK]

Gents,

Is it mandatory mechanical test qualification for welders as per ASME B31.8 sour gas service requirement as per clause B823.2?.

Qualification by RT is acceptable ?.

Thanks & Regards

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.

Because it is a repeated work, pipeline standards ask for DT and it is a right thing to do.

It is highly recommended to follow this method of qualification.

RT is not as effective as DT for screening good welders in pipeline projects.

Hi, 

Can we accept the welders as per RT qualification?. If mechanical test omitted will be it violation of B31.8?.

Ibrahim,

If you are proceeding after the fact and want to elude from the requirements use my below clause.

or i agree with Mr.Ramin go for destructive which will be before the fact and proactive side.

Thanks.
