Abstract
Through to cold weld the three kinds of steel precision components and analyze the welded joints .the results prove that: a certain degree of the solid phase transformation have been found in this area from the metallographic microstructure graphs.And there are a lot dendritic crystals and lath martensiles,which have good mechanical properties,had been produced in fusion area and weld area.At ihe same time,some cementite carbide particles diffuse at the grain boundary and they ensure the welded joints have good mechanical properties.According to the microhardness curves,it have been found that the same material cold welding obtain the best mechanical performance.The weld hardness reach 680 HV after weld M2 with CMC-M2.In the dissimilar steel welding,the weld hardness can reach 600 HV after weld GCrl5 with CMC -M2.So cold welding the same steels have the minimal impact on the performance differences.关键词
