Welding method and apparatus |
摘要 |
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 filter housing which contains a chamber within which a fluid is placed. The fluid absorbs undesired wavelengths of radiation from a heating source before the radiation reaches the welding zone. A heat exchanger may be connected to the filter in order to cool the fluid during the filtering process. |
