PURPOSE: To prevent generation of construction in a conductor and to improve connection strength, when an exposed conductor part in laser welded while superimposing the exposed part, by pushing and moving the exposed conductor part to a welding part side. CONSTITUTION: One end 20a of an electrical wire 20 with an exposed conductor part 22 formed in the middle is fixed with a retaining zig 52. The other end 20b is placed on the receiving plate 61 of a forcing mechanism 60 and held by a driving roll 63 that is provided on the rotary shaft of a motor 62. A second cable 30 is arranged crosswise on the first cable 20, and the exposed conductor part 32 of the cable 30 is superposed on that 22 of the cable 20. Both ends 30a, 30b of the cable 30 is depressed by the retaining zig 52. The superposed part 40 from both exposed conductor parts 22, 32 is irradiated with a laser beam 57, and the motor 62 is also operated, moving the other end 20b of the cable 20 pushing and moving in the direction of the arrow A. The constructed part generated in the welding zone is replenished with a conductor material, and the molten conductor is solidified in a state the construction is eliminated. |
