appearance of weld

基本解释

The appearance of weld is better and the welding process with low spatter is more stable when the arc is a critical one.
采用临界潜弧区域的焊接规范参数施焊，飞溅小，工艺过程稳定，焊缝成形优良。
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。
In this paper, arc voltage of PMIG welding is controlled by Fuzzy controller. The welding arc is steady in welding process and the appearance of weld is good.
本文介绍作者拟对脉冲熔化极气体保护焊（PMIG焊）焊接过程中的电弧电压参数进行模糊控制，取得了良好的焊接电弧稳定性和焊缝成形的效果。
