Friction welding as joining method has a good joining condition. The results of FSW welding have the advantage that the surface is smoother and flatter than the results of arc welding. Friction rotary welding includes several stages, namely material welding and microstructural analysis. In this study the material welding was used copper and aluminum alloy 1100 with sizes 60mm, 50mm, 0.5mm and macro structural analysis using a digital microscope. Experiments were carried out using lap joints with dimensions of 100mm, 50mm, 0.5mm with variations in loading parameters of 30kgf, 40kgf, 50kgf and variations in shoulder diameters of 4mm, 6mm, 8mm. In the experiment, the larger the diameter of the shoulder, the greater the loading required to connect the two materials, but if the loading is too large, it can cause defects in the welding results. The welding results at the welding pressure parameter of 40kgf with a shoulder diameter of 8mm show that welding with these parameters is capable of performing welding because the areas of the welding results are evenly connected and there are no holes (hooks) in the welding results. The results of welding at a welding pressure parameter of 50kgf with a shoulder diameter of 8mm show that the results of joining the copper and aluminum are mixed evenly but damage the surface of the copper. The macro structural results show that the welding pressure affects the shoulder diameter, if the welding pressure is too large and the shoulder diameter is too small it will only damage the copper and aluminum material because it only has a thickness of 0.5 mm, and vice versa if the welding pressure is too small and the shoulder diameter is too large, the two materials cannot be connected. In this study, the best results were obtained with a shoulder diameter of 4mm and a pressure of 40kgf because there were no defects or holes in the welding results.

“…To the best of our knowledge, few works have been reported in the literature on the hardening behavior and its evolution after direct friction welding. In this trajectory, Kumar et al [15] have used four temperatures (ambient, 550, 600, and 650 °C) to account for the degradation in the mechanical properties of Super 304HCu steel upon reducing the temperature. Using Hollomon's law, the obtained predictions results showed that the work hardening occurred in two stages.…”

The main objective of this work is to analyze structural hardening by direct friction welding on two austenitic materials of the AISI 304L and AISI 316L series, that were welded separately (similar welding) followed by a combined (mixed) welding. The friction welding parameters such as rotation speed, applied pressure (friction and forging), and holding time were carefully selected and optimized. Forty welding operations and thirty post-welding nominal tensile tests were performed, with the sole purpose of obtaining the rational curves. To achieve this objective, the results of the tensile tests were collected and analyzed. The rational curves allowed us to proceed by classical analytical modeling to quantify the effect of welding on the work-hardening behavior of the two stainless steel samples. The microstructure of each welded joint condition was analyzed and compared to each other.
