Welding set of metal member including permanent magnet and welding method thereof, as well as electric rotating machine
A welding set and a welding method that suppresses the unnecessary magnetization of a permanent magnet member by a welding current when welding one metal member including a permanent magnet member and the other metal member together are obtained. The welding set is provided with a work retaining part 3 that retains a work 14; a pressure device 4 located over the work retaining part 3 with a work-providing space interposed; a first welding electrode 8 mounted on a moving part 4a of the pressure device 4; a second welding electrode 10; and a welding transformer 11 that supplies a welding current to both of the welding electrodes 8, 10. Both of the welding electrodes 8, 10 are located on one end side of the work 14 with respect to one metal member and the other metal member respectively, as well as are located so that there is no permanent magnet member 18 between respective abutment terminal of one metal member and the other metal member.
