Welding technology play important role in manufacturing and gas metal arc welding is one of the most popular welding methods. There are many input parameters that affect the quality of the welding seam such as welding current, welding voltage, welding speed, etc. One of the problems in controlling welding robot is determining the optimal parameters that maximize the quality of welding. There are several designs of experiment techniques can be used to get the desired results with small number of experiments. In this paper, Taguchi method and response surface methodology are chosen to estimate the value of residual stresses of the seam path of welding two metal plates. In case of response surface methodology, both Box-Behnken design and central composite design are used in determining the optimal parameters. The estimation of residual stresses is done by ABAQUS software. The comparison among the designs is done and many conclusions about the optimal parameters and mathematical model are presented.
