以304不锈钢对焊试板为研究对象，分别沿母材、全焊缝以及垂直焊缝方向进行取样，探讨了采用接头横向拉伸试验获得焊缝屈服强度的合理性，同时对比了几种取样方式所获得的抗拉强度和断后伸长率的差别。结果表明：接头横向拉伸试验获得的屈服强度介于母材试样的与全焊缝试样的之间，且使用不同标距长度的引伸计及不使用引伸计所获得的屈服强度也存在较大的差异，屈服强度的测试结果受所选引伸计的影响极为显著；接头横向拉伸试验获得的抗拉强度也介于母材试样的与全焊缝试样的之间；而接头横向拉伸试验所获得的断后伸长率则远远低于母材试样的及全焊缝试样的。

Taking the 304 stainless steel butt-welded test plate as the research object, specimens were taken along the direction of the base metal, full weld and vertical weld, and the rationality of using the transversal tensile test of the welded joints to obtain the yield strength of the weld was discussed. At the same time, the difference in tensile strength and elongation after breaking obtained by using different sampling methods was also studied. The results show that the yield strength obtained from transversal tensile test of the joint was between that of the base metal specimen and that of the full weld specimen. And the yield strengths obtained by using extensometers with different gauge lengths and without extensometer were different. In other words, the yield strength was greatly influenced by the selecting of extensometers. The tensile strength obtained from transversal tensile test of the joint was also between that of the base metal specimen and that of the full weld specimen. However, the elongation after breaking obtained from transversal tensile test of the joint was much lower than those of base metal specimen and full weld specimen.
