Here we have investigated the possibility of using active thermography for detecting surface cracks in welds. This technique features advantages such as non-contact and high speed. The weld is illuminated using an infrared light source. Due to higher energy absorption in a surface crack, the ...
Finally, a controlled spot welding condition was suggested to prevent surface cracks. 展开 关键词: spot welding zinc-coated steel expulsion surface crack liquid metal embrittlement DOI: 10.2320/matertrans.M2013244 被引量: 2 年份: 2014 收藏 引用 批量引用 报错 分享 ...
In this paper, A modeling method based on coordinate transformation is proposed, which can solvethe SIF of 3D crack at weld toe of sphere-cylinder combined shells. The accuracy of the proposed methodis then verified by calculating surface cracks in pipe and T-shape intersections. Meanwhile, the...

Whether a crack is straight or curved can give clues to the stresses present in the failed part, the direction of the loading, the microstructure of the material, the presence of defects, and the speed of the fracture. Curved cracks often are related to mixed mode fractures (Mode I/Mode ...

The Mk values of shallow cracks (a/t ≤ 0.1–0.2) are sharply raised as a result of the weld toe notch stresses. For intermediate crack depths (0.2 ≤ a/t ≤0.9) the Mk-value drops slightly below 1.0 before increasing once more when the crack approaches the rear surface. In the case...
