The consistent replacement of traditional iron-based alloys with light and special alloys and their combination with traditional ones is one of the main trends of modern industry.From a technological point of view, this creates problems related to the welding of dissimilar metals, which traditional welding methods cannot cope with.Another important factor driving interest in the technologies of joining dissimilar metals is, in particular, the problem of replacing parts and products made of copper and its alloys with hybrid ones that are joined by welding. In this case, all types of welding do not guarantee a high-quality connection.The topicality of this topic is determined by the fact that copper is a more noble metal compared to, for example, aluminum (about 2-4 times). Its value is constantly growing due to the rapid increase in demand for it in almost all sectors of the economy, especially in electrical engineering, electronic industry and energy. At the same time, aluminum is very close to copper in terms of thermal and electrical conductivity (~60%), with much lower density (~30%) and cost.All this has become a powerful motivation to create a large-scale project "JOIN 'EM" [6], [7] within the European Union, aimed at researching welding processes of various metals (mainly products made of copper - aluminum alloys) using the pulse welding method magnetic as the most suitable solution to this problem.This project was established in 2017 and operates under the Research and Innovation Program Horizon 2020 of the European Union [8].Most of the publications from MIZ are devoted to the research of welding technology of tubular parts. MIZ sheet metal technology was proposed much later and is currently attracting great interest from researchers.
