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 partthat retains a work; a pressure devicelocated over the work retaining partwith a work-providing space interposed; a first welding electrodemounted on a moving partof the pressure device; a second welding electrode; and a welding transformerthat supplies a welding current to both of the welding electrodes. Both of the welding electrodesare located on one end side of the workwith respect to one metal member and the other metal member respectively, as well as are located so that there is no permanent magnet memberbetween respective abutment terminal of one metal member and the other metal member.
