PROBLEM TO BE SOLVED: To provide an electromagnetic welding machine capable of mounting and taking out a weldment, and facilitating exchange of upper and lower platy coils to serve actual use. SOLUTION: To a machine stand 1 fixed with the lower platy coil 2 insulated by a insulation material 3, a movable frame 6 fixed with the upper platy coil 4 is pivoted movably for opening/closing, and on the lower platy coil 2 and the upper platy coil 4, concentration parts 10, 11, in which currents concentratedly flow respectively, are provided so that the concentration part 10 of the lower platy coil 2 and the concentration part 11 of the upper platy coil 4 are made to oppose to each other. |
