| 摘 要： | 采用正交试验法,选用L934正交表,以氦检漏泄漏率作为考核指标,对影响焊接效果的电压、脉宽、离焦量和转速四个因素进行试验研究,最终优选的工艺参数组合为A3B2C1D2,即电压为36档,脉宽为3.5ms,离焦量为+1.0mm,转速为3/7r/min。此方法对其它工艺参数的优化研究具有指导和推广意义。

| Abstract: | By adopting Orthogonal test and L934 orthogonal table,taking helium leak detection leakage rate as evaluation index,the Voltage,Pulse Width,Defocusing Amount and Rotational Speed which affect the welding effect are studied.The final optimization process parameter is A3B2C1D2,i.e.,voltage 36,pulse width 3.5ms,defocusing amount ＋ 1.0mm,rotational speed 3 /7r/min.This method is proved instructive and worth popularizing. |
