Re: [MW:27093] Re: Impact Testing requirement for welding procedure qualification

There are 2 things which need to be considered.

1. Base Material Impact requirement.

As specified in API 5L which need to be part of MTC and decided based on OD.

2. Welding Procedure Impact test.

It depends on the Design Code and the corresponding fabrication code.

Thanks & Regards
