Abstract:The present investigation provides an assessment of the influence of the force parameters of rotary friction welding (RFW), namely the friction force and the forging force during welding tubular samples with a diameter of 73 mm and a wall thickness of 9 mm from Cr-Mn-Mo steel G105 according to API 5DP in connection with AISI 4340 The microstructure, microhardness, tensile mechanical properties and impact strength of welded joints after welding and after post-weld stress-relieving tempering were studied. The ev… Show more
