网络熔透焊道; 根部焊道

The factors influencing the penetration during bead welding the thin plate was investigated. A model about pulsed gas metal arc welding ( P-GMAW) formation of weld based on radial basis function network ( RBFN) was set up.
分析了薄板平板堆焊熔透的影响因素，利用径向基函数网络（RBFN），建立了脉冲熔化极气体保护焊（P-GMAW）的焊缝成形过程模型。
The penetration of welding bead is hard to be checked directly in practice, so the control on the penetration of welding bead is mainly realized by adjusting the related factors.
由于焊缝熔深在实时状态下难以直接检测，因此，对焊缝熔深的控制主要是通过调节与其相关量来实现的。
Aiming at the different penetration modes of pulsed GTAW with wire filler, the problems of controlling the topside and backside weld bead shape are proposed.
针对填丝脉冲GTAW过程的不同熔透状态，提出了焊缝正面和反面的成形控制问题。
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。
