Abstract
Influence of preheating temperature on delayed fracture of HAZ metal has been assessed. It is established that in order to ensure a high resistance to delayed fracture, preventing cold cracking in the joint HAZ metal, the cooling rate w_6/5 should not be higher than 5 °C/s. In this case it is necessary to apply preheating at the temperature above 200 °C.
