Motor rotor lead joint intermediate frequency welding device

The utility model is applicable to the welding field, and provides a motor rotor lead joint intermediate frequency welding device, which comprises an intermediate frequency induction coil, a magnetizer and a fixed baffle; and the magnetizer is spliced in the intermediate frequency induction coil and is fixed by the fixed baffle. The device provided by the utility model is small in size, so a worker can very easily and conveniently operate, and the labor intensity is reduced; since the principle of skin effect is utilized, the area can be fast heated, the temperature of a workpiece can reach to higher welding temperature within several seconds, and the work efficiency can be improved; and since heating is fast, and heat conducting to the outside is less, the damage on the insulation of the coil can be reduced, and the insulating property of the coil can be improved.
