Upset Resistance Welding of Aluminium to Steel, M.Sc. Thesis Sharif University of Technology ; Kookabi, Amir Hossein (Supervisor) ; Movahedi, Mojtaba (Supervisor)
Abstract
Aluminum and steel are the most utilized metals in industry and joining of them has many applications including heat exchangers and parts in aluminum extraction process. In this research, Upset Resistance Welding of aluminum to stainless steel was studied. In this regard, the effect of current intensity, time of welding, in-situ post-heating operation and post-heating operation in the furnace were investigated on the microstructure, mechanical properties and electrical resistance of welds. The currents of 2.25, 2.30 and 2.35 kA and times of 55, 60 and 65 cycles were applied for welding. Then in-situ post-heating conducted under currents of 1.75, 2.25 and 2.75 kA and 10 cycles on the sample...
