Historical re-trials in the friction welding of dissimilar metals (Al-SS) in India

The increasing need for joining dissimilar materials and the varied requirements of various industries have made it necessary to develop joining techniques which are capable of joining dissimilar materials with ease and efficiency. Among all materials, iron-based alloys and aluminium-based alloys are finding multifarious applications in a wide variety of industries. The purpose of this research is to assess the development of solid-state joints between dissimilar materials, i.e. Al 6063 (aluminium alloy) and SS 304 (stainless steel alloy), using a continuous- drive friction welding process. Friction welding tests were conducted on two different machines, viz. a lathe and a vertical milling machine. The results were analysed by means of a tensile test, a macrostructure test and a macrohardness test in order to determine the phases which occurred during welding. This report delineates studies of many researchers dealing with the same subject, the experimental work conducted by the authors of this research paper and its analysis to widen the knowledge in the area of the friction welding of dissimilar metals.
