METHOD FOR WELDING PARTS FROM HETEROGENEOUS METALS BY PRESSURE

摘要

A method for welding parts from heterogeneous metals by pressure, at which current pulses are passed along the welding area on part, which has higher electrical resistance of metal and for selection of the parameters of current pulses previously obtained dependences of the area of ​​development of physical contact of welded surfaces on the amplitude of current density and total specific density of processing are used and considering that the minimum area of ​​physical contact should be not less than 40 % the amplitude of current density and corresponding total specific energy of treatment are selected.
