Abstract
In work the model of stress calculation and analysis of stress field during single-pass SAW (Submerged Arc Welding) surfacing have been presented. In the temperature field solution, influence heat of melted electrode and heat of direct impact of electric arc have been taken into consideration. The phase change kinetics according to the laws of Johnson-Mehl-Avrami-Kolmogorov and Koistinen-Marburger were determined. The temperatures of the beginning and the end of the changes were determined by the Ac1 and Ac3 temperatures during heating and on the basis of the timetemperature-transformation welding diagram for cooling. The stress state of thermal loaded flat has been described assuming planar section hypothesis and simple Hooke’s law and using integral equations of stress equilibrium. The stress-strain curves were modeled as the curves of the mixture of individual material phases depending on temperature. The analysis of stress state has been presented for SAW surfacing S355 steel plate.
