FIELD: method of application of metal coats on detachable contact connectors.
SUBSTANCE: proposed method is used for stabilization of contact resistance of connectors at level of initial assembly during entire period of operation in parts made from copper, aluminum and their alloys during assembly, operation and repair of electrical plants and plants manufacturing electrical equipment. Proposed method includes cleaning and degreasing the contact surfaces, applying liquid flux on these surfaces, preheating the surfaces and applying the metal coat; preheating is continued to temperature of 40-45C; metal coat is applied by means of local contact fusion and gallium alloy having melting point not above 30C is applied as metal coat at thickness not exceeding 0.1 mm.
EFFECT: reduction of contact resistance.
