“…Different methods of experimental design have been used in various studies, such as orthogonal array based on Taguchi [3], [12], [20], [21], factorial design [22], central composite design [22]- [24], response surface methodology [23], [25], [26] and D-optimal design [27]. One of the drawbacks of full factorial design is that it requires a large number of trials, which can be costly and time consuming [3].…”

Purpose: MIG welding is a type of arc welding that uses a continuous solid wire electrode and a shielding gas to join two metals by heating them with an electric arc. Process parameters including current, voltage, preheat temperature and post-weld heat treatment were studied. Then, optimize process parameters of experiments done in previous work using a Taguchi Orthogonal Array (L27) design. Methodology: A grey based Taguchi method is used to optimize the process parameters. The analysis of variance (ANOVA) is applied to assess the significance of the input parameters on the response parameters. A mathematical model is developed using multiple linear regression equations. Findings: Results of this research show that it is possible to get higher strengths of weld joints using Taguchi design. Increasing current (I) and post-weld heat treatment temperature (PWT) increases strength of the studied welded joints, and vice versa. Unique contribution to theory, policy and practice: Future research should validate the findings of the current research through experimental investigations.
