金属材料焊缝的有损检验.弯曲测试

[中文适用范围]： 本文件规定了对取自对接焊缝、带堆焊的对接焊缝（分为复合板焊缝和复合焊缝）和不带对接焊缝的堆焊试样进行横向根弯、面弯和侧弯试验的方法，以揭示焊缝的缺陷。 或在弯曲测试和/或评估延展性期间处于张力下的测试样本表面附近。 它还给出了测试样本的尺寸。 此外，本文件还规定了当母材、热影响区和/或焊缝金属在弯曲方面的物理和机械性能存在显着差异时，替代焊接接头横向弯曲试验的方法。 本文件适用于采用任何焊接工艺制成的具有焊接接头的所有形式产品中的金属材料。 [外文原描述]： This document specifies a method for making transverse root, face and side bend tests on test specimens taken from butt welds, butt welds with cladding (subdivided into welds in clad plates and clad welds) and cladding without butt welds, in order to reveal imperfections on or near the surface of the test specimen which is under tension during bend testing and/or assess ductility. It also gives the dimensions of the test specimen. In addition, this document specifies methods to be used instead of transverse bend tests with a former for welded joints when base materials, heat affected zones and/or weld metal have a significant difference in their physical and mechanical properties in relation to bending. This document applies to metallic materials in all forms of product with welded joints made by any welding process.
