Abstract: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. We studied process parameters including current, voltage, preheat temperature and post-weld heat treatment. We optimize process parameters of experiments done in previous work using a Taguchi Orthogonal Array (L27) design. A grey based Taguchi method is used to optimize the process parameters. The analysis of variance (ANOVA) is applied to assess the sign… Show more
