Abstract
A filter for absorbing electromagnetic radiation which is used in heating a welding zone wherein a first part is joined to a second part. The filter includes a solid material for absorbing undesired wavelengths of radiation from a heating source before the radiation reaches the welding zone. The filter also has a housing which contains a chamber within which a fluid is placed. The fluid cools the solid material and also may absorb undesired wavelengths of radiation from the heating source before the radiation reaches the welding zone. A heat exchanger is connected to the filter in order to cool the fluid during the filtering process.
