Abstract
A method of brazing a plurality of copper strands to a buss bar includes: a) cleaning the buss bar and the copper strands; b) positioning a filler shim on the surface of the buss bar; c) placing a copper strand on the filler shim, the filler shim and the strand having substantially equal lengths; d) stacking additional copper strands on the buss bar, with a filler shim between each adjacent pair of strands; and e) heating the filler shims utilizing an induction brazing coil to a temperature sufficient to cause melting of the shims and to thereby form a brazed lap joint between the copper strands and the buss bar.
