welding bead

基本解释

The fatigue life of the surface cracks of the weld toe and the central part of the welding bead are calculated.
又算出了这五种形状角焊缝趾端部和焊肉中央处的表面裂纹疲劳断裂的寿命。
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.
提出了一种基于等离子弧焊的直接金属成形新方法，通过对成形工艺的试验研究，确定了焊接电流、成形速度与成形轨迹宽度之间的对应关系；
