Abstract
Structural transformations in the HAZ metal of steel 10G2FB under the impact of the arc welding thermal cycles and their effects on the mechanical properties of this region of a welded joint were investigated. The range of permissible cooling rates of the HAZ metal at temperatures of 600-500 °C, providing properties of the welded joints at a level of requirements to the base metal and their high resistance to delayed, brittle and laminated fractures, was identified.
