标准范围

ISO/TS 20273:2017提供了设置与疲劳相关的适当焊接质量要求的指南。ISO/TS 20273:2017适用于厚度为>；3 mm，承受循环荷载。由于缺乏铝焊缝和超高强度钢的实验数据，疲劳强度（或S-N）曲线仅适用于最大规定屈服强度为960 MPa的结构钢。本文件中的验收标准可适用于高强度钢、不锈钢，以及焊接结构中常用的5000和6000系列铝合金的某些概念。在缺乏相关公布数据的情况下，建议通过特殊测试对其进行量化。

ISO/TS 20273:2017 provides guidance for setting appropriate weld quality requirements in relation to fatigue.ISO/TS 20273:2017 is applicable to fusion (arc and/or beam welding) welded steel plate-type structures having a thickness of >3 mm, which are subjected to cyclic loading.Due to lack of experimental data for aluminium welds and ultra-high strength steels, the fatigue strength (or S-N) curves apply only to structural steel up to a maximum specified yield strength of 960 MPa.The acceptance criteria in this document may be applied to higher strength steels, stainless steels and certain concepts to 5000 and 6000 series of aluminium alloys which are commonly used in welded structures. In the absence of relevant published data, it is recommended that this be quantified by special testing.
