In this paper, the influence of welding thermal cycle on the microstructure and properties of 15MnMoVNRe steel in the weld zone was analyzed. The safety t_ (815) and t_ (100) values and the minimum presumed temperature to prevent delayed crack were put forward. The influence of humidity on The task of further research; proposed ways to improve the welding process.
