A purpose of work - an increase of reliability of details of machines. A research method is theoretical and technological researches of processes of surfacing and welding. The paper deals with welding of dissimilar metals titanium and aluminum alloys pressure methods. It was found that the back-up rolls are operated at high specific pressures and high speed surfacing process developed wire electrode at a low heat input. A study to identify the composition and amount of harmful emissions during surfacing aluminum alloy cored wire. The technological scheme of production of powder strip and its formation in the camp. A scheme of layered filling of the core components in the shell, which enables to produce a powder strip with a high fill factor. Presented patterns speed impact on the formation and physical properties of welded joints. Coating materials have been developed with the nitrogen to which allow to obtain a metastable austenite in the surface layer of the deposited metal.
