Abstract :
Correlation between weldability and improvement inproperties is a key issue in materials science research. Theobjective of this work is to optimize the process parameters viz., aging temperature, aging time, solutionizing time, to enhance the hardness of Al6061 alloy. Hence, the present paper deals with hardness study of TUngsten Inert Gas welded 6061 aluminium alloy after age hardening under three different aging temperatures, aging time and solutionizing time using Taguchi L9 Orthogonal array. Finally, a second order model has been generated for
hardness using Response Surface Methodology with 20 runsfor full design. Thepredicted and experimental results are
in good agreement.
