###### Abstract
Only if both conditions are sufficiently met can a successful chip bonding process be achieved during the extrusion process. The parameter of critical shear stress is directly influenced by the extrusion ratio [21]. Thus, with a larger extrusion ratio, the effective shear stress increases [18; 22]. [PERSON] et al. showed that there is a promising possibility to produce deposition rods for tungsten inert gas welding utilizing friction stir extrusion of EN AW 6082 machining chips [23]. The main aim of this research is to investigate the possibilities and challenges during the welding of solid-state-recycled EN AW 6082 aluminum alloy. The authors of this paper did not find any research articles dealing with the joining of solid-state-recycled materials. Therefore, there is a significant research gap in this area. To perform semisolid recycling in this research, EN AW 6082 aluminum alloy machining chips were cold compacted and directly hot extruded to create solid samples. To obtain EN AW 6082 aluminum alloy sheets for welding, the hot rolling process was utilized afterward. It has already been shown that hot rolling can have a beneficial effect on solid-state-recycled specimens [24; 25; 26]. The welding of SSR specimens can be a challenging task due to the increased oxide particle content. It is known that because of the specific solid-state recycling procedure, specimens have a somewhat increased level of aluminum oxide, and for the 6 xxx aluminum alloy series a magnesium oxide particle content as well [27]. [PERSON] et al. showed that the overall oxygen content increased at every step of the recycling process for AA 6060 aluminum alloy. Furthermore, according to the authors, the initial thin Al\({}_{2}\)O\({}_{3}\) layer on the chips are covered by a MgO layer during pre-annealing and hot extrusion. Thus, alloying elements, such as Mg, are also involved in oxidation. This results in a ten-fold increase in the oxygen content in the extrudate accompanied by a complex network of oxides with an average thickness of 290 nm and a low density [7]. In aluminum, welding aluminum oxide presents several challenges in welding because it has properties that interfere with the quality and integrity of the weld. Aluminum oxide has a much higher melting point (about 2000 \({}^{\circ}\)C) compared to pure aluminum (about 660 \({}^{\circ}\)C). This means that when you try to weld aluminum, the oxide layer does not melt as easily as the aluminum beneath it, making it difficult to achieve a clean, consistent weld. If not removed, the aluminum oxide layer can create a barrier between the molten aluminum and the welding material. This barrier leads to poor fusion, weak bonds, and potential porosity, compromising the weld's strength and quality. Aluminum oxide can trap impurities and moisture from the environment. During welding, these impurities can lead to defects, contamination, and reduced weld quality. To overcome these challenges, welders typically employ mechanical cleaning, chemical cleaning, and AC (alternating current) in tungsten inert gas (TIG) welding, where the positive half-cycle helps to remove the oxide and, of course, using inert shielding gas to minimize oxidation during welding [28; 29; 30]. For the welding of the specimens in this research, both metal inert gas welding (MIG) and TIG methods were used to ensure a wider range of the process parameters and heat input, which is known to exert great influence during aluminum welding. TIG was also performed on one side and on two sides for the same reasons as stated above. Welding processes were conducted for solid-state-recycled specimens but also for conventionally produced specimens, which resulted in a total of six welding procedures being performed and analyzed.
