ISO 17642-2:2005规定了通过以下方式进行自我约束冷裂纹试验的试样尺寸、试样和程序:
CTS(受控的热严重性)试验
以获取焊接过程中冷裂纹敏感性的相关信息。
本国际标准主要适用于但不限于碳锰钢和低合金钢。
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.
