N2 - The given article studies the changes in thermal cycle and cooling rates of steel 30XΓCA weld joints at various distances from the weld center using modern thermal imaging equipment. The analysis of the experimentally obtained and calculated thermal cycles showed that the calculated cycles almost match the experimental ones in terms of quality but the time distribution of calculated values is 4-5 times smaller than that of the experimental ones. On the base of experimental results and theoretical investigation of the thermal cycles for fusion-welding in CO 2 we have developed an improved formula for calculating heat conduction for machine single-pass welding. The difference between the calculated and experimental values of thermal fields does not exceed 10%.
