标准范围

ISO 17641-2:20 05规定了进行自约束热开裂试验所需的试样、试件尺寸和应遵循的程序。描述了以下测试:T型接头焊缝开裂试验；焊缝金属拉伸试验；纵向弯曲试验。这些测试旨在提供有关焊缝金属热裂纹敏感性的信息。这些测试不适用于母体材料的评估。本国际标准主要适用于全奥氏体不锈钢；镍、镍基和镍铜焊接金属。它也可用于其他焊接金属。ISO 17641-2:20 05仅描述了如何进行测试和报告结果。它没有给出任何验收标准。

ISO 17641-2:2005 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.This International Standard applies primarily to fully austenitic stainless steels; nickel, nickel-base and nickel-copper weld metals. It can also be used for other weld metals.ISO 17641-2:2005 describes only how to carry out the tests and report the results. It does not give any acceptance criteria.
