METAL CORED WELDING METHOD AND SYSTEM USING ROTATING ELECTRODE

摘要

Methods and systems are disclosed for utilizing metal cored welding wire electrodes with forced movement of the electrode (44) and arc. The electrode (44) may be moved by a motion control assembly (62) comprising a motor (66) in a welding torch (24). The arc is established only between the sheath of the metal cored electrode (44) and the workpiece (14) (or weld puddle), providing a unique transfer mode for enhanced deposition, travel speeds, and other weld and process characteristics.
