Experimental Research on the Effect of the Rotary Friction Welding Process on Carbon Steel AISI 1030

The aim of this study is to investigate the rotary friction welding (RFW) technological parameters when welding two parts with medium carbon steel AISI 1030. Rotary friction welding has several parameters that can influence the quality of the weld joint. In this study, the adjustable and observable parameters are selected, i.e. friction pressure and friction time. The samples welded are observed in microstructure and their Rockwell hardness is measured to consider the effect of the parameters. The results reveal that friction pressure and friction time are the main factors of this welding process. Besides, the microstructures and hardness change in the welding zone because of the difference in the welding temperature.
