Abstract

Al-65032 is an Aluminum alloy used for construction of aerospace structures such as wings.  This alloy can be welded by TIG or MIG welding. Hence establishment of welding parameters and their optimization for good quality weld is utmost important factor. As it is a heat treatable alloy and is generally heat treated, the welding parameters are to be designed keeping in view of the properties obtained after heat treatment. In this work, Taguchi parameter design is used to design the process parameters that optimize the mechanical properties of weld specimen. The process parameters of the TIG welding setup considered are gas pressure, current, groove angle and pre-heat. Assigning the process parameters to L-9 orthogonal array, experiments are conducted and the optimization condition is obtained along with the identification of most influencing parameters using S/N analysis and mean response analysis. ANOVA is also carried out to reaffirm the same. A confirmation test is conducted to ascertain the optimized condition.
