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.
又算出了這五種形狀角銲縫趾耑部和銲肉中央処的表麪裂紋疲勞斷裂的壽命。
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.
由於銲縫熔深在實時狀態下難以直接檢測，因此，對銲縫熔深的控制主要是通過調節與其相關量來實現的。
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.
提出了一種基於等離子弧銲的直接金屬成形新方法，通過對成形工藝的試騐研究，確定了銲接電流、成形速度與成形軌跡寬度之間的對應關系；
