Aluminium alloys are applied in various industries because of their high strength to weight ratio. Aluminium Alloy
8011 is also lightweight, corrosion resistant and has high wettability. It is being currently used in various applications such as
Storage tankers, Military equipment, high pressure containers, Air conditioning foil etc. The aim of this research is to study the
effect of TIG welding using butt weld joint on microstructural and mechanical properties of Aluminium Alloy 8011.
