impact test on welding overlay body of valve

impact test on welding overlay body of valve

In case of welding overlay on valve’s body and taking into consideration that the valve’s specification requires for impact test (at specific conditions) for pressure containing parts, I would like to ask whether the welded overlay area shall be impact tested.

If the welding overlay is not considered as part of design criteria then an impact test of the welding overlay material is not required. Please refer to API 6A par. 6.5.1.2.2.b.

The life of a valve can be considerably extended at a fraction of the cost of a solid corrosion resistant alloy valve by the application of a weld overlay to valve internal surfaces
