Abstract
Friction welding is a solid state joining process and is widely being considered for aluminum alloys. 7075 is an aluminum alloy, with zinc as the primary alloying element. Due to its strength, high density, thermal properties, High strength precipitation hardening, 7075 aluminum alloys are extensively used in aerospace industry. It has good fatigue strength and average mach inability, but has less resistance to corrosion than many other Al alloys. These alloys are difficult to join by conventional fusion welding techniques. This paper aims at exploring the possibility of welding this alloy using friction welding. Tensile Strength, Hardness values, Flash parameters with respect to upset pressure and Microstructure of the 7075 were studied.
