Purpose is to hold a variety of sheet objects, flow and microstructural transformations models to specify the parameters of the models, and on this basis to formulate a mathematical state of the problem about the thermomechanical processes in the multi-layer surfacing. Theoretical studies were carried out on the basis of the quasi-static thermal mechanics of inhomogeneous inelastic bodies with temperature-dependent properties, the growing model of inelastic bodies, thermo-kinetic diagrams of austenite decomposition. The mathematical model of stress-strain and the microstructural state of sheet bimetallic parts with a multilayer reconstructive surfacing were developed. A number of simplified models for evaluation of residual stress-strain and microstructural state weld sheet metal parts with different methods of attaching them in the process of welding were suggested.
