RT Journal Article SR Electronic A1 Żurawski, Paweł T1 Analysis of the Welding Process of Steel Pistons of Internal Combustion Engines JF Manufacturing Technology Journal YR 2022 VO 22 IS 4 SP 494 OP 509 DO 10.21062/mft.2022.048 UL https://journalmt.com/artkey/mft-202204-0003.php AB The aim of the article is to analyze the friction welding process of steel pistons, due to the small amount of scientific literature on this subject. First, it is necessary to present the design fea-tures of steel pistons and their advantages and disadvantages. Then analyze the types of friction weld-ing processes used in the production of pistons of internal combustion engines with the analysis of their differences. Present two basic methods of welding in the production of steel pistons, i.e. friction butt welding and low pressure friction welding. Finally, a proper analysis of the friction welding pro-cesses of steel pistons of internal combustion engines can be presented. At the end, the conclusions of the analysis are presented and proposals for improving the process are made.
