The automated system for welding fused by an electrode with pulse giving of a wire and modulation of arch�s current. The block diagrammed and a principle of work of automated management by welding process. Is described the developed equipment for realization of welding process.
Key words: metal active gas, automated control by welding process, pulse giving of a wire, modulation of arch�s current

Pervukhina O. L., Saykov I. V., Pervukhin L. B., Chayadarov F. B. � Deformative and thermodynamic processes at titanium explosive cladding of cylinders

Titanium deformation structural features at high speed swaging of a titanium tube are considered. Thermodynamic conditions of titanium explosion welding are covered. It is shown that in order to obtain cylinder qualitative cladding by titanium it is necessary to eliminate conditions for localization occurrence of the heat-related changes and for titanium transition into plastic state at conducting the process in the shielding gas. Lengthy current conductors from copper + titanium over 30 diameters long are obtained.
Key words: explosion welding, deformation localization, adiabatic shear bands, thermodynamic conditions
