Inspection of laser weld on seams on pipe coils
In this application, two main problems are encountered during laser weld inspection: Due to the proximity to the welding process, the laser scanner is exposed to a large amount of ambient light. Moreover an extremely high ambient temperature has to be taken into consideration as well.
The Q4-80 system delivered by QuellTech features water cooling and a protective pane, which represents a reliable insulation against weld chips and other kinds of pollution. Particular interference filters are provided as well, to eliminate the influence of secondary light. For the same purpose, increased laser power of laser class 3R is used. Tolerances for the laser weld bead can be adjusted by means of configurable software.
By means of the rugged QuellTech system, the client from now on is able to monitor the quality of the weld seams inline and in a reliable manner. Measuring results can be documented with the QS-View Software.
