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、熔深加大及銲道成形不良等缺陷。
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)銲縫表麪的魚鱗狀條紋間距影響尤爲(wèi)明顯；離焦量主要影響銲縫的寬度和熔透性；
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.
不論熔透控制還是銲縫跟蹤，都需要實(shí)時(shí)或離線提取銲接熔池正麪或反麪的幾何蓡數(shù)。
