Abstract
The paper provides analysis of the state-of-the-art and confirmation of the relevance of studying the process of magnetic- pulse welding (MPW) of flat parts from similar and dissimilar metals. Results are presented of studying the possibility of performance of magnetic-pulse welding of flat samples in a modified batch-produced N-126A unit, using an experimental flat rectangular inductor. Process scheme is given. Technology is described for producing joints of flat metal parts 1.0–1.5 mm thick of similar materials of A5N and AMG2 alloys, as well as dissimilar materials – copper, A5N alloy and ANG2 alloy to 12Kh18N10T stainless steel (cold-worked). Conducted metallographic studies showed that a common feature for MPW of similar and dissimilar metals is specific bonding of welded plates in the zones (regions) equidistant from the center of the inductor flat turn. Thickness of mobile plates becomes smaller, and microhardness in the welding zones becomes higher. Sound welding was found within the two-zone joint shape. Welded joint quality was assessed by the results of mechanical strength testing. 10 Ref., 1 Table, 9 Figures.
