Consumable insert as per ASME IX

Consumable insert as per ASME IX

Postby hanyu » Mon Dec 23, 2013 8:44 am

Dear forum members,
Regarding GTAW process I am aware of the classical method when a filler metal is used for the filling of the gap but recently I have received procedure and welder qualifications by welding supplier and seen that "consumable insert" is used. Could anyone explain me what is the consumable insert and if I can omit it for the production weldings without requalification of the procedure and the welder.
Thanks

Hanyu,

consumable insert - filler metal that is placed at the
joint root before welding, and is intended to be completely
fused into the root to become part of the weld.

Addition or Deletion is a non-essential variable for WPS but it is an essential variable for the welder.
Hope that helps,
Cheers,
BB

Ballbearing,
Thank you very much for the valuable support! Are you able to tell me where to find the reference paragraphs within ASME IX?

Hanyu,

The definition of consumable insert is included in QW/QB-492. Regarding procedure you shall go through the table QW-256 and see the variable QW-404.22 (nonessential variable) and for the welder you shall go through the table QW-356 and see the same variable number (QW-404.22, the addition or deletion of insert is essential variable).

regards,
