“…To address these limitations, continuous drive friction welding (CDFW) has emerged as a promising technique for joining dissimilar drilling steels. CDFW involves the application of frictional heat generated by rotational motion, followed by the application of forging pressure to create a solid-state bond [15][16][17] . This method offers several advantages over traditional welding techniques, including lower heat input, minimal residual stresses, and without brittle phase formation [18][19][20] .…”

42CrMo medium carbon steel and 36Mn2V alloy steel were successfully jointed using continuous drive friction welding. The effects of forging pressure and post-weld heat treatment on microstructure and mechanical properties of joints were investigated in detail. Results reveal that with increasing the forging pressure, the tensile and yield strength increase firstly and then decrease. The as-welded joint with the highest yield strength (708 MPa), largest elongation (14.2%), and high impact toughness (57.24 J) were obtained with the 35MPa forging pressure. After post-weld heat treatment, the joint yield strength, elongation, and impact toughness were increased to 798 MPa, 18.1%, and 71.02 J, respectively. The microhardness measurement results indicate that the as-welded joints show higher Vicker hardness than the two base metals. After post-weld heat treatment, the microhardness was decreased owing to martensite elimination. The above findings provide a basis for the implementation of friction welding of dissimilar steels used for drills in the coal-mining industry.

This study investigates the effect of pressure (burn‐off and forging) on the mechanical properties of the joint between a wear‐resistant tool steel and a low‐alloy steel using linear friction welding. The authors have previously demonstrated the feasibility of joining these dissimilar materials, but the impact of pressure on the mechanical properties of the bimaterial joint remains unclear. To address this, weld samples are prepared using different pressures and are characterized through microstructural analysis, microhardness, tensile testing, and fractography. The results show that the strength of the joint between the wear‐resistant tool steel and the low‐alloy carbon steel increases as the pressure increases up to a certain point, after which a decrease is observed. The highest joint strength is achieved at a pressure of 360 MPa. The microhardness profile measurement reveals a distinct transition zone at the interface between the two materials, with varying hardness values. The hardness of the low‐alloy carbon steel increases near the interface, while that of the wear‐resistant tool steel decreases. This transition zone is found to be narrower at higher pressures. Microstructural characterization shows that the grain structure near the interface differs from that of the starting base materials.
