appearance of weld

基本解釋

The appearance of weld is better and the welding process with low spatter is more stable when the arc is a critical one.
采用臨界潛弧區(qū)域的焊接規(guī)范參數(shù)施焊，飛濺小，工藝過程穩(wěn)定，焊縫成形優(yōu)良。
Use alternating transverse magnetic-field to control dragged arc, overcome weld undercut, and improve the appearance of weld.
所以控制電弧后拖是高速焊改善焊縫成形的關(guān)鍵。
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.
本文介紹作者擬對脈沖熔化極氣體保護焊（PMIG焊）焊接過程中的電弧電壓參數(shù)進行模糊控制，取得了良好的焊接電弧穩(wěn)定性和焊縫成形的效果。
