Light waveguide welding, involves deriving welding parameter from measured intensity of light emission propagating in optical waveguide during welding in comparison with desired value

摘要

The method involves measuring the intensity of the light emission (18) propagating in an optical waveguide (12,14) during welding and deriving a welding parameter from the measured intensity value in comparison with a desired intensity value. The welding parameter is the welding current and the intensity of the light emission emanating at the free end of the waveguide is measured Independent claims are also included for the following: an arrangement for welding light waveguides.
