Abstract

Pure aluminium has very low strength, yet many of its alloys are stronger than ordinarystructural steels. Aluminum alloy especially 6061 is so strong that they could be used in armour structures and aerospace applications. In spite of these properties,defects such asporosity,hot cracking and stress corrosion cracking during welding of aluminium alloy is yet to be optimized.The main objective of this paper is to determine the favourable welding conditions for 6061 aluminium alloy. Tungsten Inert Gas Welding based on design of experiments has been conducted to achieve this goal. Hence this paper concentrates on experimentally identifying the effect of different welding parameters on hardness and weld pool geometry under different welding condition obtained by L9 Orthogonal array using Taguchi’s design of experiments.
