Welding device

The utility model discloses a welding device which is used for welding a material belt and comprises a rotary table mechanism, a plurality of jigs, a hanging frame and a welding mechanism. The plurality of jigs are arranged on the turntable mechanism at intervals and are used for placing and fixing the end parts of the material belts; the hanging rack is arranged on the turntable mechanism, is positioned among the plurality of jigs and is used for hanging a plurality of material belts; the welding mechanism is arranged adjacent to the rotary table mechanism, and the rotary table mechanism is used for sequentially rotating the jigs to the working area of the welding mechanism so that the welding mechanism can weld the ends of the material belts on the jigs. When the welding device is used for welding the end part of the material belt, as the material belt is hung on the hanging frame, an operator does not need to assist the material belt in keeping the material belt still, so that the labor intensity of the op
