Thirdly, with the modified Gurson model of the MARC finite element method soft, the damage behave of the welded joint was simulated. It was found that in the undermatched welded joint, the damage mainly happened in the soft weld line and with the decrease of the weld line抯 width, the damage抯 development was faster. As for the overmatched welded joint, the results showed that the damage mainly happened in the soft base metal and with the increase of the weld line抯 width, the damage抯 development was faster. While the width of the weld line was narrower than three millimeters, the high strength weld line could improve the anti-damage capability of the overmatched welded joint.

通过计算发现在低匹配的焊接接头中，损伤主要发生在低强度的焊缝中，并且焊缝宽度越小，焊接接头的损伤就越严重；而在高匹配的焊接接头中，损伤主要发生在紧临焊缝的强度较低的母材上，随高强度焊缝宽度的增加，焊接接头的损伤发展程度加剧，当焊缝宽度小于3mm时，高强度焊缝的加入对焊接接头能起一个强化的作用，提高了焊接接头的抗损伤能力。

The methods of adaptive median filter, variance ratio of interclass and intraclass segmentation, and mathematical morphology were used to decrease the noise of original welded seam image, to extract welded seam region, and to carry on high frequency enhancement transformation for the interior of extracted welded seam with frequency range sharpening.
