Under what circumstances is post-weld heat treatment required for pressure vessel welding?
Heat treatment is used to achieve the required mechanical properties of steel or welded joints. In particular, after hot rolling or hot pressing of steel plates, the organization or performance in the supplied state is destroyed; or by using electroslag welding (BSW) or high energy line welding, the grain size of the weld is coarsened, which can be eliminated through post-weld normalizing treatment.
