针对焊接接头性能测试与焊接工艺评定中常易引起分歧或者相关标准没有明确规定的一些问题，诸如通过横向拉伸试验获得接头的屈服强度与断后伸长率是否合理，拉伸试样平行段长度对试验结果的影响，拉伸/弯曲试样焊缝余高是否去除，热影响区冲击试样缺口位置的规定等，根据自身的工作经验以及大量的文献查阅，对相关标准规定之间的区别进行了阐述，并从理论上进行了分析与讨论。鉴于不同标准对同一测试项目的不同规定易造成试验结果之间的显著差异，建议尽快对统一相关标准的可能性和可行性进行讨论。

Considering the existing problems that easily lead to divergence or are not clearly defined in standards for welding joints performance test and welding procedure qualification, such as the rationality of yield strength and percentage elongation after fracture obtained from the joint transversal tensile test, the effect of parallel section length of tensile specimens on the test results, whether the weld reinforcement being removed for the tensile/bending specimens, the definition of notch position of impact specimens for heat affected zone (HAZ) and so on, the differences among the relevant standards were described according to own work experience and a large number of literature reviews, and the reasons that caused the different results were analyzed and discussed in theory. In view of the present situation of different standards on the same test items easily leading to significant differences in test results, it is recommended as soon as possible to discuss the possibility and feasibility of reunification of relevant standards.
