Abstract

Abstract: Aluminium alloys gathers wide range of acceptance and potential application in automobile, aerospace, ship building industries, off shore structures & construction of bridges owing to its low weight, superior strength to weight ratio and other anti-corrosive properties. In the realm of welding processes of aluminum and its alloys, the TIG welding continues its peak spot because of its flexibility and versatility in adaptability. Present investigation reports the deformation behavior of AL6082 & AL8011 butt welded joint during tensile tests. TIG welding was performed in the rolling direction of two aforementioned dissimilar aluminum alloys. The Rockwell hardness testing technique was employed. These tests were carried out on the weldments to ascertain the joint integrity prior to characterization to have an idea of the weld quality. Many considerations come into the picture and one has to balance to reach to an optimized combination of various welding parameters. Therefore, present study focused on evaluating and exploring the influence of various welding parameters on ultimate tensile strength and hardness of the welded specimens by conducting tensile experiments.
