Abstract

Abstract The objective of this research work is to present the mechanism of rotary friction welding of two dissimilar steels (X70 steel and duplex stainless steel). The selected rotational speed was maintained during the welding process. The welded sample was characterized by optical microscopy and hardness measurements. The welding sequence was presented. The duration and the mechanism of different welding stages have been determined. Optical observation revealed distinct zones in the welded joint. The Vickers hardness profile showed the difference in hardness across the welded joint.
