Flexible induction brazing wand for hollow tubes

摘要

The brazing wand comprises a hollow helically wound electrically conductive tubular member for conducting an electrical current and for conducting a coolant therethrough. The electrical current is used to heat a member to be brazed while the coolant is used to control the temperature of the brazing wand. The brazing wand also comprises a flexible cable for conducting the electrical current and coolant to the heating portion of the wand.
