“…CDFW of HDPE was conducted utilizing a lathe machine equipped with a pneumatic system fabricated in the laboratory to control the welding process parameters, as shown in Figure 1. The same setup was used for welding different materials, such as aluminum and steel, as indicated in Tashkandi and Mohamed [5]. Thus the present experimental setup that uses a lathe machine to perform the welding is valid.…”

“…Another study by Li et al [4] analyzed the joint quality of AA6061-T6 rods through friction torque, temperature, microstructure, and axial shortening. The ef-fect of friction time on the joint quality based on TS and macrostructure for AA6061 was demonstrated in Tashkandi and Mohamed [5]. Yilbas et al's [6] study of friction-welded aluminum bars is among the first studies investigating friction welding for aluminum alloys.…”

Continuous drive friction welding (CDFW) is a solid-state joining procedure that can be used to join various similar and dissimilar materials. High-density polyethylene (HDPE) is a thermoplastic that can replace many traditional materials. Utilizing experimental design procedures such as response surface method (RSM) is a reliable approach for determining the most significant process parameters and optimizing the desired responses. The current study employed an RSM experimental design to investigate the effects of the process parameters for welding HDPE rods using CDFW. The design evaluated the process parameters and three outcome responses: the maximum welding temperature, the axial shortening, and the tensile strength (TS). The combination of the three responses can allow achieving high-efficiency welds. The results showed that it was possible to achieve high-efficiency welds while maintaining axial shortening and controlling temperature. A TS >65% of the parent material's strength with an axial shortening of <3 mm was achieved.

“…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] . Hardik et al [21] used CDFW to weld copper-stainless steel pipe.…”

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.

“…He further showed that obtained weld joint strength increased by increasing the burn off length and rotational speed. Mohammed Tashkandi et al [11] joined the Al 6061 alloy and analyzed the effect of friction time on the mechanical properties of the welded joint. He found that when friction time increased up to 5s, joint strength increased, and further increment decreased the strength of the joint.…”

Joining of the similar & dissimilar materials alloys using heat of the friction in currently being used, especially for non-ferrous alloys which are considered as non-weldable alloys. Al 2024-T6 & Al 6061-T6 having length of 70mm and 12mm diameter were welded by using the friction welding process. Similar and dissimilar welded samples were obtained by applying different combinations of welding parameters like friction pressure 30bar, forging pressure from 50 to 60 bar, and rotational speed of 2200 rpm. Vickers microhardness and Tensile test was performed on similar and dissimilar welded samples. Test shows that ultimate tensile strength and hardness of the similar welded joint was greater than their respective base metals welds. Dissimilar weld samples have hardness and ultimate tensile strength greater than the base Al 6061-T6, and less than the base Al 2024-T6. From results, it was clearly shown that as forging pressure increased from 50 to 60 bar, ultimate tensile strength and hardness of the similar and dissimilar welded samples increased. Joints were analysed to investigate the fractography of all welded samples. All welded samples fractured on the base metal alloy and show the formation of the cup and cone like structure which indicate the ductile fracture of the joints.
