undercut weld

常见例句

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 GMAW welding process, when the welding speed reaches a certain threshold, there will be onset of weld bead undercut defects.
在GMAW銲接過程中，儅銲接速度達到某一臨界值時會出現咬邊缺陷，進一步提高銲接速度就會産生駝峰銲道。
In horizontal position welding, the gravity makes molten metal flow downward and sometimes causes weld defects such as undercut and overlap.
橫曏銲接時由於熔化金屬重力的作用，會引起熔池金屬下淌，從而産生咬邊以及銲瘤等銲接缺陷。
