| Abstract: | Welding method of submerged arc welding was used to the plate butt welded joint of 16MnDR,and the microstructure of the welded joint was observed,mechanical properties test and micro-hardness test were also carried out.The results of experiments shows that the tensile strength of the welded joint were not less than that of 16MnDR steel,and no crack appeared in side bend test.In addition,the low temperature impact toughness of the welded joint is excellent.Peak hardness appeared in the heat affected zone.Mic... |
