A method of pressure welding, at which to connect a first workpiece made of dispersion-hardened nickel alloy, which structure comprises eutectic strengthening phase, with a second workpiece made of dispersion-hardened deformed nickel alloy, all interior and odd-layer microlayers are made of alloy which by its chemical composition corresponds to the eutectic composition of the strengthening phase of the first workpiece, the composition of even microlayers and thickness of the microlayers are set so that the composition of the layer as a whole corresponds to the composition of the first workpiece, the heating process of the connecting area of workpieces is conducted up to the temperature of melting of strengthening phase of the first workpiece followed by stopping heating, and increase of compression force, or without it. |
