The authors studied the specifics of the kinetics of austenite decomposition in the near-weld region of the heat-affected zone, as well as the weld metal under the welding process conditions used in the construction of main gas pipelines made of promising K80 strength grade steels. An approach to selecting rational cooling rates during welding is presented.
