Cold cracking



Cold cracking is a defect that occurs in welding and requires all the following preconditions:

  • susceptible microstructure (e.g. martensite)
  • hydrogen present in the microstructure (hydrogen embrittlement)
  • service temperature environment (normal atmospheric pressure): -100 to +100 °F
  • high restraint

Additional recommended knowledge

Eliminating any one of these will eliminate this condition.
