WebDefects Inspection: Although the strength of steel forgings are much better than steel forgings, it may also exsit defects, we can distinguish the defects into surface defects and inner defects. For surface defects such as trimming, cold shut, dents, ects, are mainly tested by 100% visual inspection or MPI (Magnetic particle inspection). WebDec 14, 2005 · Forging defects are not widely discussed in the literature because of a natural reluctance by forgers to draw attention to them. There are many imperfections that can be considered as being defects, ranging from those traceable to the starting materials to those caused by one of the forging processes or by post forging operations.
WebAdvantages and Disadvantages of Forging 1. Introduction to Forging: Forging can be defined as the controlled plastic deformation of metals at elevated temperatures into a predetermined size or shape using compressive forces exerted through some type of die by a hammer, a press or an upsetting machine.
