I would like to ask about radiographic inspection after the welding of the surfacing layer is completed
Thread Content
For a container, after the surfacing layer (4 mm thick, intended only for corrosion protection) has been welded, radiographic testing is performed on the base metal welds; it should be determined whether to include the thickness of the surfacing layer when setting the sensitivity of the densitometer and evaluating the film thickness
It should be added; your penetration thickness includes the surfacing layer
