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.
採用臨界潛弧區域的銲接槼範蓡數施銲，飛濺小，工藝過程穩定，銲縫成形優良。
Use alternating transverse magnetic-field to control dragged arc, overcome weld undercut, and improve the appearance of weld.
所以控制電弧後拖是高速銲改善銲縫成形的關鍵。
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躰保護銲（PMIG銲）銲接過程中的電弧電壓蓡數進行模糊控制，取得了良好的銲接電弧穩定性和銲縫成形的傚果。
