Abstract
The importance of the railway transport of Ukraine in its common transport system, as well as its leading role in the implementation of domestic and foreign state economic relations of the country is noted. The expediency of updating the existing railroad car park of Ukraine has been substantiated. An important role of the technological process of welding in the production of new and modernization of existing units of the car park has been noted. The direction of reduction of deformations of wagon metal structures, which arise in the process of their welding, is directed to the use of thermal repair with local heating. The mathematical description of thermal repair of wagon metal structures is presented. As an example, generalized mathematical models obtained as a result of mathematical modeling of the process of thermal change of the basic metal structures of freight wagons are given.
