The regularities of the formation of structure and properties of the eutectic alloy composition comprising an intermetallic compound CuAl 2, when welding in the solid - liquid. Found that when two surfaces are formed from the fusion of fragments of the solder joint. F ormer land discontinuity in operation become the centers of education and delamination cracks that lead to seal failure of welded joints on the surface diffusion welding and soldering.
