This article mainly describes the numerical simulation capabilities in welding simulation programme SYSWELD. The results of the numerical model, which are listed in article except for residual stresses are compared to real experiments. Thermal fields, residual stresses and hardness were simulated. Preparation of boundary conditions for numerical simulation on real sample and numerical simulation of welding is in experimental part. Structure of programme SYSWELD and repair of high pressure gas pipeline with steel sleeve is described in theoretical part of article. Two welds connecting the distance ring and gas pipe were simulated. Simulation of welding at the repair of high-pressure gas pipeline with steel sleeve with composite filling is presented in this paper. This article deals with simulations of the welding process for applications of practice using SYSWELD software.
