Abstract
A method and apparatus for welding a first workpiece to a second workpiece having a first surface to be chrome plated welds a heat sink liner to a second surface of the second workpiece opposite the first surface. The first surface of the second workpiece is them chrome plated. The first workpiece is then welded to the second workpiece at the heat sink, which absorbs a substantial amount of heat generated by the weld before that heat can reach the chrome-plated second surface.
Claims7
A method of welding a component to a chrome-plated workpiece comprising:
- attaching a heat sink to the workpiece on a first surface opposite a second workpiece surface to be chrome-plated;
- chrome-plating the second surface;
- and
- welding the component to the heat sink.
A heat sink for use in welding a component to a workpiece comprising:
- a heat absorbing liner coupled to a first of the workpiece opposite a second surface of the workpiece to be chrome-plated.
A method of fabricating a vehicle engine exhaust treatment device comprising:
- attaching a heat sink to an interior surface of the exhaust treatment device;
- chrome-plating an exterior surface of the exhaust treatment device which lies opposite the interior surface;
- and
- welding an internal component of the exhaust treatment device to the heat sink.
