| Abstract: | The effect on softening control of 30CrMnSi joint HAZ by rotation impacting during welding was studied. The method of rotation impacting was utilized to form the real time loading on the soften area during the welding process. Vickers hardness tester was used to show the hardness of the welded joint in the heat-affected zone with different rotation impacting parameters. The microstructures of the softening zone with and without rotation impacting were observed by inverted metallographic microscope. The distribution of carbon element in the softening zone was analyzed by EDS. The results show that the softening phenomenon of heat affected zone was effectively inhibited. The mechanical properties were significantly improved. The rotation impacting can increase obviously the hardness of the joint softening zone, the ferritic content in the softening zone is increased obviously, the distribution of carbon element eliminates local segregation. |
