The paper describes how the technological issue of assuring stability of circumferential welds in mass production was solved and shows how resistance projection welding substituted for fusion arc welding. In the introduction, key technological reasons for replacing the welding process used are given. The study is supported by a detailed description of physical characteristics of resistance projection welding that assures the desired quality of a particular product. The initial experiments and analyses carried out, allowed limiting the range of the investigation conducted to a comparison of efficiency of welding with two different types of workpiece adjustment. The experimental section further includes a description of welding with front and edge adjustments and the choosing of suitable welding parameters. This is supported by the results of a quality evaluation of welds obtained in a visual examination, tensile testing, and a metallographic analysis.
