composite design with 31 runs and an algorithm was developed to optimize the fusion zone grain size and the tensile strength of pulsed current gas tungsten arc welded AA6061 aluminium alloy joints... AA6061 aluminium alloy was welded without any weld defects. Due to wide ranges of factors, it was decided to use four factors, five levels, and rotatable central composite design matrix to optimize......
