Abstract
A method of forming a brazed joint between an armature bar and a hydraulic header clip including: assembling an end of the armature bar, hydraulic header clip and a substantially phosphorous-free braze material; positioning the assembly of the armature bar, hydraulic header clip and the braze material in a braze chamber, such that the clip is seated in an induction heating coil; heating the assembly to a first temperature within 200 degrees F. of and below a solidus temperature of the braze material by applying electrical current to the induction heat coil; heating the assembly to a second temperature above the liquidus temperature of the braze material; pooling liquid braze material on ends of the armature bar, and cooling the assembly and thereby forming a braze layer on the end of the armature bar.
