A Review On Rotating Arc Welding Process

Abstract Rotating arc welding also known as spin arc welding utilises a unique weld torch in which the welding electrode rotates in a circular motion at a high rate of speed. Centrifugal force propels molten droplets across the arc creating a consistent and sound weld bead. This enables high deposition rate welding for significant increase in productivity. The present paper discuss the effect of welding parameters such as voltage, current, rotating frequency, rotating radius, etc., on weld bead geometry especially in narrow gap welding. Also various output parameters like tensile strength, hardness and microstructures of different weldments were also considered in the study.
