Zusammenfassung:	A heating apparatus (200) is provided for use during a welding Operation on a component. In one embodiment, the apparatus (200) includes a die (202) having a cavity (206) having at least a portion shaped to complement a first portion of the component and an opening (212) providing a space through which a second portion of the component extends. A primary heating element (214) is embedded in the die (202) and generates heat upon being energized. A die temperature sensor (216) is embedded in the die (202) proximate the primary heating element (214) and senses primary heating element temperature and supplies a temperature signal representative thereof. A component temperature sensor (218) is embedded in the die (202), and senses a temperature of the component in the cavity (206) and supplies a temperature signal representative thereof. A controller (220) couples to receive the temperature signals and is operable, in response thereto, to selectively energize and de-energize the primary heating element (214).
