METHOD OF ARC DEPOSITION OF COPPER AND COPPER ALLOYS ON STEEL

摘要

FIELD: process engineering.SUBSTANCE: invention may be sued for making working parts from steel with deposited copper or copper alloy layers adding to their antifriction properties, rust resistance, electrical conductivity, etc. Pasty flux is applied on steel part surface to be built-up to weld copper filler strip by spot seams. Then, arc deposition is performed in argon using nonconsumable electrode and filler of copper or copper alloy with complete fusion of aforesaid welded strip.EFFECT: reduced requirements to qualification of welders.3 cl, 1 tbl
