The fatigue life of the surface cracks of the weld toe and the central part of the weldingbead 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 method that on-line identifies parameters of the model through the information of temperature on the weldingbead 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。
