探討異種金屬電阻點銲最佳參數之研究

本研究主要目的在於雙相不銹鋼(SAF 2507)及鎳基超合金(Inconel 600)進行電阻點銲之製程中探討最佳製程參數。其使用直流電之電源供應器來進行電阻點銲實驗，電極頭材質為鉻鋯銅之平面電極，並以點銲的抗剪強度作為評價銲件之品質特性，為了有效率的獲得此製程之最佳參數值，本研究應用田口方法(Taguchi Method)，搭配四種影響之控制因子即充電電壓、銲接時間、電極加壓力、電極頭尺寸來最佳化點銲製程參數，並透過變異數分析(ANOVA)找出各參數對製成的影響程度。實驗結果顯示最佳參數組合為A1B3C1D1，其參數分別是充電電壓300V、銲接時間4sec、電極加壓力4kg和電極頭尺寸4mm，此參數組擁有較高平均抗剪強度，而在變異數分析中可得到電極頭尺寸因數對此次製程影響最大，貢獻值達64.8%。

The main purpose of this study is use duplex stainless steel (SAF 2507) and nickel-base superalloys (Inconel 600) to find the optimizing the quality in DC power supply for resistance spot welding. the chrome zirconium copper alloy for the electrode tip material plane electrode, and shear strength as a quality spot welding pieces of property evaluation, in order to obtain the most efficient process of this good parameter values, this study Taguchi method (Taguchi Method), with the impact of the four factors that control the charging voltage、welding time、electrode force and electrode tip size to optimize the process parameters, and through variance analysis (ANOVA) to find out the degree of influence of each parameter on the manufacturing process. Experimental results show that the best combination of parameters is A1B3C1D1, the parameters are 300 V in charging voltage, 4 sec in welding time, 4 kg in electrode force and 4 mm in electrode tip size, this parameter has a higher average shear strength, and in the analysis of variance can be get the electrode head size factor greatest impact on the manufacturing process, the contribution value of 64.8%.
