Re: [MW:9013] Groove weld qualification for fillet weld

Manpreet,
 
There is not any catch point in Sec.IX to limit your fillet weld material thickness or weld deposit thickness even when impact testing is applicable.
 
You have to just follow QW 451.3 limits only.
 
Why is that you qualified a fillet PQR for an impact tested application, instead of supporting any groove weld PQR?
 
Regards,
 
A.Praveen

Dear Jaspal,

QW-403.6 is applicable for minimum base metal limits for impact tested qualification, What i m asking is that, QW-451.4 is stating that a groove weld qualification shall be qualified for all thickness of fillet weld, does that mean, we need not to follow QW-451.1 & QW-403.6....  

Somebody please answer this query......

Regards
Manpreet Singh
