Magnetically impelled arc butt welding (MIAB): a comprehensive review on welding parameters, microstructure, and joint performance

Magnetically impelled arc butt welding (MIAB) is a solid-state pressure welding technique used to join tubes and pipes, which does not require edge preparation and filler material. Heating the material on both the tube surface ends by producing a rotating arc using an electromagnetic force improves the arc rotation. Applying the forging pressure on the movable end of the tube will join with the other end surface of the tube. Unlike conventional welding, the weld formation is developed with a single-step process without several passes. The parameters such as welding current, exciting coil current, coil position, and gap size between the tubes influence the weld strength. This review focuses on MIAB welding stages with process parameters and MIAB welded of similar and dissimilar materials, including the microstructure of weld and joint performance and the process parameters that affect the property of welded materials and researcher inferences; applications were discussed.
