Weld Repair Procedure as per API 1104

[waqas suleman]

Dear Members,

We qualified Welding Procedure on API 1104, now our Client is demanding Weld Repair Procedure Qualification.

In scope Weld Repair Procedure Qualification is not mentioned.

I need expert judgement that is it mandatory to qualify Weld Repair Procedure for each welding procedure in API 1104.

Dear JUJULAL,

Thanks for your comment, but my question is, is it Mandatory requirement to qualify separate Weld Repair Procedure Qualification.

[JIJILAL K M]

That will be with respect to your client requirement, which shall included in the weld specs. However API1104, article     10.2 REPAIR PROCEDURE says

'When a repair welding procedure is required, the procedure shall be established and qualified'

If your project requires, there you should have to get  the approval of Job Procedure/method of statement for Full and partial repairs and its WPS prior to Welding procedure Qualifications.

hope you got cleared

Dear Waqas,

It is not mandatory to qualify a repair WPS & PQR as per API 1104.

However, as a good construction practice it is better and advisable to establish and qualify the repair WPS & PQR as you don't expect all weld joints to be 100% defect free. Secondly, if you find any defect in any of your weld joints then will you be going for complete weld joint cut out instead of repairing only the required defective area.

Regards,
