The welding of aluminum magnesium alloy has superior mechanical characteristics, but the feasible setting for the welding parameters of the TIG (Tungsten Inter Gas Arc Welding) or GTAW (Gas Tungsten Arc Welding) has many difficulties due to some hard and crisp inter-metallic compounds created within the weld line. Normally, the setting of welding parameters does not have a formula to follow; it usually depends on experts’ past knowledge and experiences. Once exceeding the rule of thumb, it becomes to be impossible to set up feasibly the optimal parameters. Consequently, this study will develop a solution to solve the problem of multiple quality characteristics when we weld the aluminum magnesium alloy plate. The selecting welding quality characteristics are Non-destructive testing (Welding positive thickness, Welding width and Depth-width ratio) and destructive testing (Impact Test and Tensile Test). It uses TOPSIS (Technique for Order Preference by Similarity to Ideal Solution), ANN (Artificial Neural Network) and all combinations to find the optimal function framework of parameter design for welding plate of aluminum magnesium alloy. The research results can improve the welding efficiency for relevant welding industries
