标准摘要
[中文适用范围]： 本部分ISO 17641规范了试验用试样、测试片尺寸和为进行自拘束热裂纹试验所遵循的程序。描述的试验如下：T-joint焊缝裂纹试验；焊接金属拉伸试验；纵向弯曲试验。这些试验旨在提供关于焊接材料热裂敏感性的信息。试验不适于评估母材。本部分主要适用于奥氏体不锈钢、镍、镍基和含铜镍焊金属。也可用于其他类型的焊接金属。本部分ISO 17641仅说明如何进行试验和报告结果，并不给出任何接受标准。 [外文原描述]： ISO 17641-2:2015 specifies the required specimens, the test piece dimensions, and the procedures to be followed to carry out self-restraint hot cracking tests. The following tests are described: - T-joint weld cracking test; - weld metal tensile test; - longitudinal bend test. The tests are designed to provide information about the hot cracking sensitivity of weld metals. The tests are not suitable for the assessment of parent materials. ISO 17641-2:2015 applies primarily to fully austenitic stainless steels, nickel, nickel base, and nickel copper weld metals. This part of ISO 17641 can also be used for other weld metals. ISO 17641-2:2015 describes only how to carry out the tests and report the results. It does not give any acceptance criteria.
