Joining copper and aluminium current-conducting elements is quite often applied in electrical industry. Direct contact of such elements without welding is accompanied by running of electrochemical corrosion and resultant increase of transient resistance, which rises during operation. Any kind of welding these materials leads to formation of intermetallics of AlnCu type, which can affect (or not affect) the electrical properties of the joint. Explosion welding is the most efficient method to produce copperaluminium electric conductors with higher performance. The need to manufacture bimetal copper-aluminium products of various shapes by explosion welding requires development of the respective technological processes. 4 Ref., 5 Tabl., 10 Fig.
