The welding process plays a central role in the welding industry, where the joint zone undergoing the welding process experiences structural and mechanical property changes. This research evaluates the comparison of current strength and parameters in the directional welding joint model, a critical aspect of addressing common weaknesses in welded joints. The research objects include four current levels (100, 120, 140, 160 A) and three types of welding directions (longitudinal, transversal, and combination). The aim of this study is to detect the optimal combination in welded joints that can produce a maximum tensile strength ratio. The research method involves tensile testing on various specimen models of joint types at specific current strength levels. The research results indicate that at the current strength level of 120 A, the combined directional welding joint model (longitudinal+transverse) provides a maximum tensile strength reaching 335.370 MPa. This finding stands out significantly, surpassing the tensile strength values at other current levels and welding model types, such as at 100 A (331.574 MPa), 140 A (332.315 MPa), and 160 A (332.685 MPa). This discovery highlights that the combined joint model yields a substantial improvement in joint strength, making it an optimal solution for various current strength levels and joint models. The key feature of this research involves specific recommendations for the welding industry, including guidelines on selecting optimal parameters to enhance the tensile strength of joints. The directional welding joint models can be a reference in designing welding procedure specifications to incorporate construction elements using ST 42 material. This research contributes both theoretically and practically, offering opportunities for improving efficiency and structural safety in the welding process, thus positively impacting the quality of joints in construction and manufacturing applications

In this paper, the effect of different shapes of tool pin on the plastic flow of 2024-T6 aluminum alloy during friction stir welding was studied. In order to observe the plastic flow of materials more clearly, we chose the method of friction stir welding of dissimilar materials, considering the different corrosive characteristics of aluminum alloys made of different materials when exposed to the same corrosive liquid. By studying and comparing the temperature field, macro and microstructure, microhardness and tensile properties of welded joints, the results indicated that the metal in the weld nugget zone (WNZ) mainly came from the base metal of the advancing side, the thread being the driving force of the downward movement of the FSW plastic metal. The deep groove thread tool pin had the strongest ability to drive the metal downward. The conical cam thread tool pin had the strongest stirring effect on materials and the best metal fluidity. The macroscopic morphology, microstructure, mechanical properties and fracture morphology of different joints were analyzed, and the results showed that all joints could form an excellent union, with an onion ring pattern appearing in cross-section. The minimum grain size of the WNZ formed by the conical cam thread stirring head was 7~12 μm; the hardness was least at the junction of the heat affected zone (HAZ) and the thermo-mechanically affected zone (TMAZ). However, the hardness of the weld formed by the conical cam thread at this point was higher than that of other stirring heads; the tensile strength of all joints was more than 80% of the BM, and the maximum tensile strength of the joint welded by the conical cam thread tool pin was 364.27 MPa, accounting for 86.73% of the base metal (BM). The elongation after break was 14.95%. Tensile fracture morphology analysis showed that all joints were fractured by plastic fracture.
