Abstract
A copper sleeve is employed to join a molybdenum disilicide heating rod with a conductor by a brazing process including fluxing the interior of the sleeve, positioning the sleeve partially over one end of the heating rod and heating the junction of the sleeve and rod in a nonoxidizing flame while applying a brazing alloy to the interior of the sleeve. The conductor is then crimped to the opposite end of the sleeve for providing an electrical and mechanical connection of the conductor to the heating rod.
