FIELD: resistance welding of metal with high heat conductivity such as copper, aluminum, their alloys and metals with coating on base of such metals.
SUBSTANCE: metallic layer of powdered self-fluxing chrome-nickel alloy with high electric resistance (kind of alloy is given in description of invention) and with total content of nickel and chrome 70 - 80%; C, Si, Mn, B, Fe - the balance. Such powdered alloy is applied by thickness no more than 0.3 mm onto surface of welded part. During welding melt metal of such layer is displaced by action of axial loads onto periphery of spot formed by welding.
EFFECT: enhanced operational reliability, improved quality of welded joint, enlarged manufacturing possibilities of welding.
