Cracks, growing at weld toe, tend to form at numerous sites along the transverse width perpendicular to the applied stresses.
焊趾处萌生的裂纹往往在垂直于作用应力方向沿着横向宽度在多处形成。

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。
