penetration bead

常见例句

But the associated problems are arc-blow, increasing the penetration and poor bead characteristics.
然而，这极易导致电弧偏吹、熔深加大及焊道成形不良等缺陷。
Moreover, the welding speed effects on the fish-scale spacing and the defocus distance on the weld bead penetration and weld width mainly.
扫描速度对焊缝表面的鱼鳞状条纹间距影响尤为明显；离焦量主要影响焊缝的宽度和熔透性；
It is necessary to extract molten pool geometrical parameters in real time or to extract back bead width off-line either in seam tracking or in penetration control.
不论熔透控制还是焊缝跟踪，都需要实时或离线提取焊接熔池正面或反面的几何参数。
