Investigation on Joining of Aluminum and Mild Steel by Friction Stud Welding

摘要: Joining of dissimilar metals has various automotive, aerospace, nuclear, chemical, and cryogenic applications. The present study focuses on friction stud welding aluminum mild steel. Experiments had been conducted by varying the process parameters strength welded joints was evaluated. Experimental results show that speed rotation, time, axial shortening distance have significant effect impact joints. dissipation frictional heat from weld center in temperature gradient across joint, causing different zones with microstructures. Scanning electron microscope (SEM) micrograph reveals presence three distinctive regions heat-affected zone, namely, fully plasticized deformed partially unaffected base metal zone. microhardness values were measured joint. At interfacial region, there is an increased plastic deformation. This due...
