System for applying an isolation layer to a brazed end of a generator armature winding bar

A system for forming a brazed joint between an armature winding bar and a hydraulic header clip comprising:

• an assembly of free ends of hollow strands and solid strands of the armature winding bar positioned within the hydraulic header clip;
• a silver based braze alloy interleaved between the strands, wherein a portion of the braze alloy extends axially beyond the free ends of a plurality of the solid strands and the free ends of a plurality of the hollow strands extend axially beyond the braze material;
• said assembly of the free ends, hydraulic header clip and the braze alloy mounted in a braze chamber, such that the clip is seated in an induction heating coil of the chamber, and
• a controller receiving a temperature feedback signal from a temperature sensor in the chamber and controlling a temperature in the chamber by controlling power applied to the coil and based on the feedback signal,
• wherein during a brazing period said coil heats the assembly to a temperature above the liquidus temperature of the braze alloy.
