| 摘 要： | 以氦-氩混合气体为保护气氛,采用正交试验和方差分析的方法,对AZ31镁合金板材进行了TIG焊工艺参数的优化。结果表明:电流对焊接质量影响最大,焊接速度次之,气体流量影响最小。获得良好焊逢的最佳工艺参数为:焊接电流58 A,焊接速度15 mm/s,氦-氩混合气体流量95 ml/s。计算确定了最优工程平均及变动范围的置信区间。

| Abstract: | Taking the He-Ar mixed gas as protected atmosphere,TIG welding process parameters for AZ31 magnesium alloy plates was optimized by using the method of the orthogonal experiment and variance analysis.The results show that the current intensity has the greatest influences on the welding quality,then welding rate,the gas-flow rate is the least.When the current intensity,welding rate and gas-flow rate of He-Ar mixed gas are 58 A,15 mm/s and 95 ml/s,respectively,the good quality weld joint is obtained.The optimal engineering average and the confidence interval of variation range are calculated. |
