标准摘要
[中文适用范围]： 本标准规定了通过以下方式进行自约束冷裂纹试验的试件尺寸、试样和程序： CTS（受控热严酷度）试验 Tekken（Y 型槽）或 Lehigh（U 型槽）试验，以便获得有关焊接过程中冷裂纹敏感性的信息。 本标准主要但不仅适用于碳锰钢和低合金钢。 [外文原描述]： ISO 17642-2:2005 specifies the sizes of the test pieces, the specimens and the procedures for carrying out self-restraint cold cracking tests by: CTS (controlled thermal severity) test Tekken (Y-groove) or Lehigh (U-groove) test 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.
