Abstract
Some ways to increase the quality of welding constructions of the sheet pieces had been proposed in this work. It has been tended to increase the quality of welding constructions at the cost of reduction of residual stresses and deformation of welding joints. It was performed the arc welding simulation of butt joints of austenitic steel. The process has been presented as a combination of force-cooling and thermal extended welding. The values of temperature of welded pieces had been evaluated by solution of partial differential equation of heat transfer with the moving heat source. The values of stresses and deformation of welded pieces had been evaluated by solution of the thermal elasticity equations. It was evaluated the functional connections between the cooling zone location and residual stresses, which allowed to calculated the optimal welding conditions to supply the minimal residual stresses and deformation of welded pieces.
