碩士 === 國立臺北科技大學 === 工業工程與管理系EMBA班 === 98 === Projection welding resistance welding is a method often used in the automotive industry on floating bump bonding is a current focus on the characteristics of the use bump to bump plate and rapid fusion method, often combined with the shape of a few bumps In the welding of different quality (such as welding strength or torque of the bearing capacity) have significant differences. In order to explore a few embossed solder joint quality of the shape of the weld, this research approach used with the M8 embossed 4 point welding nut with 1.0 t mm between the high-tension steel plate as a rival to explore parts of affected welding conditions selected A: pressure, B: welding current time, C: welding current, D: squeez pressure time four influencing factors, the analysis method by using Taguchi method，select Taguchi method of orthogonal array L8(27) and S/N ratio for the embossed pattern of the best nut welding settings (A2B2C1D2), re-assessment by analysis of variance, experimental error and identify important factors, identified by CI calculation predicted and experimental values to identify whether the overlap between the two results are close enough to prove that the Taguchi method can be applied to improve the quality of welding instead.
