The following results are obtained: with the fusion penetration increasing, the content of Mg grows, which means that evaporation loss of Mg reduces, and micro-hardness increases; 结果表明,在接头区域随着熔深的增加,Mg元素含量增加,即烧损程度减小,同时显微硬度增大;
Consequently, evaporation loss of Mg element can be controlled in a reasonable range with insured fusion penetration by proper increasing of the three parameters. 生产中,在确保焊深的前提下,可利用这一结论适当增加加速电压、束流和焊接速度,将镁元素的烧损控制在一个合理的范围内。
Influence of welding parameters on fusion penetration and evaporation loss, and its mechanism were investigated by orthogonal experiments and statistical analysis. 用正交试验及统计分析法对焊接工艺参数影响熔深和烧损的规律及机理进行了分析研究。
