| titleOfInvention | Apparatus and method for real-time evaluation of laser welds especially in confined spaces such as within heat exchanger tubing |
| abstract | Welds made by pulses of laser energy are evaluated on-line by analyzing light emitted from the weld site during application of the laser pulses. The pulses of light from the weld site are compared with base pulses generated from a good weld, and are used to calculate parameters such as heat-up rate and peak temperature which in turn, are analyzed to determine weld quality. For use in welding in confined spaces such as heat exchange tubes, and particularly the tubes in a PWR steam generator, a single optic fiber delivers the laser energy pulses to the weld site and transmits light from the weld site back to a splitter which diverts it to detectors for conversion to electrical signals used to generate a graphical display. |
