PROBLEM TO BE SOLVED: To provide a spot welding device capable of obtaining a good welding part with sputter-less.SOLUTION: A spot welding device 1 performs welding of a weld-planned part P by clamping a work-piece W by a clamp means 20 which clamps the work-piece W, bringing a second electrode 7b into contact with a conductive member 3 while bringing a contact member 4 into contact with the work-piece W from one side, bringing a first electrode 7a into contact with the weld-planned part P of the work-piece W from the other side, and then performing electric conduction between the first electrode 7a and the second electrode 7b in such a state as said above. In the spot welding device 1, the weld-planned part P is positioned in a region R of the work-piece W surrounded by a part Wa to be clamped which is clamped by the clamp means 20. |
