Stub End Machined Buttweld

Stainless steel stub end is a punching method for turning over the outer edge of the rough forgings or semi-finished product. the edge is turned into a vertical edge along a certain curve. When the edge of the stub end is a straight line, the converted deformation is converted into a curved, so it can also be said that a stub end welding method is a special form of stub end.
