Should penetrant testing be carried out on the gusset plate and the welds connecting it to the head? The standards for gussets state that penetrant testing is required for other welds; I’m not sure whether these welds are included in that category and thus require penetrant testing.
According to standards, if penetrant testing is required for the remaining welds of the lifting lug, then generally speaking, penetrant testing must also be performed on the welds of the backing plate and head to ensure the quality and safety of the welds. It is recommended to consult specific welding standards or seek advice from professionals for confirmation. .
If there’s ambiguity, just do it; anyway, PT is convenient too
It depends on the designer’s requirements; it can be done or not. It is considered an important component, so it is recommended to include it

If there are cracks in the welds on the surface of the backing plate and the head, it’s very likely that these cracks will propagate during operation due to changes in temperature or pressure. The consequences would be unacceptable
PT is performed on the remaining welds because it affects the equipment; however, the container standards do not directly reference safety standards. In safety standards, non-destructive testing of the lifting components is mandatory
