摘要
通过正交试验方差分析对16 mm厚2219铝合金电子束焊接工艺参数进行优化,以抗拉强度、弯曲角、外观质量和内部质量等为综合评定指标,得到其最佳工艺参数为:焊接电流190 mA、焊接速度850 mm/min、聚焦电流2045 mA和圆形扫描方式。
The process parameters for electron beam welding of 2219 aluminum alloy with 16 mm thickness were optimized by orthogonal experiment variance analysis. The tensile strength, bending angle, morphology and internal quality were the comprehensive assessment indicators. The results show that the best process parameters for electron beam welding of 2219 Al alloy with 16 mm thickness are welding current 190 mA, welding speed 850 mm/min, focusing current 2045 mA and circular scan mode.
