ABSTRACT:
This continuous welding apparatus has a high welding current efficiency. It includes a single drive belt mechanism having adjustable variable speeds for continuously advancing an elongated welding electrode to a welding location. The welding current is applied simultaneously through multiple contact points in the electrode by contact brushes to provide a high current for the welding operation. The brushes also serves as the carriers for advancing the welding electrode. A continuously formed weld can be made with such high efficiency welding device, and the resulting integrally formed weld is strong in strength and has a smooth surface appearance.
