Quality level B corresponds to the highest requirement on the finished weld. The quality levels refer to production quality and not to the fitness-for-purpose (see 3.2) of the product manufactured. This International Standard applies to: unalloyed and alloy steels; nickel and nickel alloys; ...
具体内容如下:焊缝余 高超高(502)、角焊缝凸度过大(503)、焊缝厚度过大(5214),下塌(504)、咬边(501)缺陷在 C 级之内,其他缺陷 需在 ISO 5817 质量等级 B 之内才能判定合格。 表3.1 2、超声波试验 实验标准:超声波试验应该根据ISO17640-2010标准进行。超声波的测试等级为B级(Testing level B)。 判定依据:...

imperfections given in ISO 5817 are modeled by a Solidworks FEM program, and they are subjected to static loading in order to determine the maximum stresses at the cross-sections of the joints.Findings: The stress values at the welded joints generally increases from the quality level of "B" ...
Requirements for smaller (more stringent) values as stated in quality level B may include additional manufacturing processes, e.g. grinding, TIG dressing. Annex?C gives additional guidance for welds subject to fatigue. ? ISO 2014 – All rights reserved ? v BS EN ISO 5817:2014 BS EN ISO ...
Three quality levels are given in order to permit application to a wide range of welded fabrication. They are designated by symbols B, C and D. Quality level B corresponds to the highest requirement on the finished weld. Several types of loads are considered, e.g. static load, thermal load...
