摘要：Investigation of MIG welding parameter optimization for surface quality is very important to improvethe technology of MIG welding application. Weld bead size and shape are one of important considerations for designand manufacturing engineers. These welding parameters affecting the arc and welding bath should be estimated andtheir changing conditions during process must be known before in order to obtain optimum results, in this case thequality surface of overlap weld beads. The process parameters such as welding voltage, welding travel speed and wirefeet rate were studied. The experiments were conducted based on a Three-factor, three-level and L9 using Taguchimethod. Taguchi methods applied to improve the quality of welding with minimum number of trails. AISI410 is usedas the work piece material for carrying out the experimentation to optimize the surface quality and hardness value. Thesurface roughness was considered as the quality characteristic with the concept of "the smaller-the-better" and hardness“the larger-the-better. It is also predicted that Taguchi method is a good method for optimization of various inputparameters as it reduces the number of experiments.
