УThe article presents the results of the development of press magnetically impelled arc butt welding (MIAB) technology using pulsed welding current and controlled precision upset allowance for the formation of joints of pipe steels and automotive parts. The research is focused on reducing energy consumption while ensuring high-quality welded joints. During the welding process, the in-process monitoring of the main parameters was performed: welding current, voltage, displacement and force at the time of upset. High-speed video recording with a resolution of up to 4500 frames per second was used to study the processes taking place in the arc gap between the pipe ends, as well as recording the main parameters of the welding cycle. The produced welded joints were tested in accordance with the requirements of international standards for gas and oil pipelines (API, DNV), which made it possible to assess their mechanical characteristics, reliability and compliance with the requirements for industrial use. 20 Ref., 4 Tabl., 17 Fig.
