The influence of solid-state welding modes on the structure of the 12Cr18Ni10-Cu system joint

This study investigates the friction welding technology for joining the 12Х18Н10Т stainless steel and copper, focusing on optimizing welding parameters and analyzing the mechanical properties of the resulting joints. The research was conducted using experimental methods to determine the optimal parameters of friction welding. Mechanical tests, including tensile strength, hardness, and microstructure analysis, were performed to evaluate the quality of the welds. The results indicate that proper selection of friction welding parameters significantly affects the quality of the joint between the 12Х18Н10Т stainless steel and copper. Optimal welding conditions were identified, leading to strong mechanical properties and reliable joint performance. Microstructural analysis revealed uniform material distribution across the weld zone. This study contributes to the understanding of friction welding processes and the effects of different welding parameters on the microstructure and mechanical properties of dissimilar metal joints. The findings provide practical recommendations for the friction welding of dissimilar materials, emphasizing the importance of parameter control to prevent defect formation and optimize joint strength. This study offers valuable insights into the friction welding process of dissimilar materials, highlighting the role of specific parameters in controlling the formation of defects and improving mechanical properties. The findings are applicable to industries requiring durable joints between stainless steel and copper. The study focused on a limited range of welding speeds and pressures. Future research should explore a broader set of parameters to further refine the welding process and address issues related to internal oxidation and joint durability.
