本文在假定电弧截面温度分布的基础上,通过对电弧内部能量平衡的研究,提出了一个横向磁场中动态电弧的近似计算模型。
Computing result indicates that quasi transverse circular arc gear is basically equal on strength distributing along tooth depth direction and it is superior to normal plane circular arc gear.计算结果表明,准端面圆弧齿轮基本上是沿齿高方向等强度分布,优于法面圆弧齿轮。
Use alternating transverse magnetic-field to control dragged arc, overcome weld undercut, and improve the appearance of weld.所以控制电弧后拖是高速焊改善焊缝成形的关键。
