Abstract
Aluminium 7075 being the workhorse of the Aluminum series has a wide range of applications in industries like aerospace, automotive, transport, etc. due to its high strength to density ratio, light weight and good corrosion resistance. It has been observed that it is difficult to weld the 7075 alloy using Tungsten inert gas (TIG) welding metal inert gas (MIG) welding or any other conventional method as it encounters solidification and recrystallization problems like cracking and porosity which hamper the weld strength. Hence, in this paper we have attempted to weld the 7075 alloy using friction stir welding, a solid state welding process that does not involve the melting of the sample and hence avoids problems related to solidification of the weld. The weld strength of the same is tested by applying tensile test, hardness test and microstructure analysis. The aforementioned tests are applied on the 7075 alloy welded by autogenous TIG welding and the weld strength of the two welding methods is compared © 2019 Elsevier Ltd.
