penetration bead

基本解釋

But the associated problems are arc-blow, increasing the penetration and poor bead characteristics.
然而，這極易導(dǎo)致電弧偏吹、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.
掃描速度對(duì)焊縫表面的魚(yú)鱗狀條紋間距影響尤為明顯；離焦量主要影響焊縫的寬度和熔透性；
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.
不論熔透控制還是焊縫跟蹤，都需要實(shí)時(shí)或離線(xiàn)提取焊接熔池正面或反面的幾何參數(shù)。
