Structure of welded joints from low-alloyed heat-resistant Cr-Mo-V pearlitic steels

V.V. Dmitrik

Ukrainian Engineering and Pedagogical Academy, Kharkiv, Ukraine

Abstract
Peculiarities of technology of CO2 automatic welding of structures from heat-resistant Cr-Mo-V pearlitic steels are considered. Technology is based on the results of modelling of temperature conditions of the welding process and provides structure in welded joints which is close to optimum.
Keywords: arc welding, heat-resistant steels, optimum structure, modelling, temperature conditions
