Study of the Effect of Friction Time and Preheating on the Joint Mechanical Properties of Friction Welded SS 316-Pure Zn

Abstract

Friction Welding (FRW) is a solid-state welding method. This technology also permits the connecting of dissimilar and similar materials while consuming less electricity than conventional electric welding. Friction welding is frequently used to join a variety of components because it generates high-quality joints and is capable of joining a wide range of materials and their complexity. This research examined the friction welding of stainless steel and pure zinc. The investigation concentrated on the welding parameters, specifically the effect of friction time and provision of preheating on parameters with high joint strength, as well as the mechanical properties, microstructure, and characterization of the joint material. The results of the experimental research indicated that the welding settings had a significant impact on the friction welding process. The tensile strength increased as a result of the reduced friction duration during the welding process, as demonstrated by the experimental findings. The longer the friction period, the more an oxide layer will form on the surface of the metal, preventing the diffusion process and impacting the production of the intermetallic phase for the joint’s strength.
