摘　　要：研究了外加永磁场对低碳钢焊缝的显微组织及焊接接头力学性能的影响，得到了在交流电焊机手工电弧焊条件下，细化焊缝显微组织，提高焊接接头力学性能的最佳磁场参数。The affections of the permanent magnetic field on the microscopic structures of the welding line of low carbon steel and the mechanical properties of the welding joint have been studied. The optimum parameters of magnetic field added permanent magnetic field by manual operations used AC arc welding machine have been given.
