the method that on-line identifies parameters of the model through the information of temperature on the welding bead surface and thus increases adaptability of model was discussed in the paper.
本文讨论了用焊道表面的温度信息对多个模型参数进行在线修正,提高计算模型的适应性。
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。
direct metal forming based on plasma arc welding is a novel rapid prototyping process. relationship among welding bead width, welding current and speed was obtained through process experiments.
