标准摘要
[中文适用范围]： 本欧洲标准规定了通过植入试验进行外部加载冷裂纹试验的背板尺寸、试样和程序，以获得有关焊接过程中冷裂纹敏感性的信息。 本标准主要适用但不限于碳、锰和低合金钢。 [外文原描述]： ISO 17642-3:2005 specifies the sizes of the backing plates, specimens and procedures for carrying out externally loaded cold cracking tests by implant testing in order to obtain information about the cold cracking sensitivity during welding. This International Standard applies primarily, but not exclusively, to C-Mn and low alloy steels.
英文名称Destructive tests on welds in metallic materials — Cold cracking tests for weldments — Arc welding processes — Part 3: Externally loaded tests
