Magnetically impelled arc butt welding of hollow and solid parts

摘要

Magnetically Impelled Arc Butt (MIAB) welding is mainly used in the automotive industry for butt welding of tubes and tubular parts 8-100 mm in diameter and 0.8-6 mm wall thickness. To extend the range of MIAB welding applications research work was conducted on different hollow and solid parts, special attention being given to welding of parts, the cross section of which is commensurable with of the active spot diameter of the rotating arc.
