“Welding-on-the-fly“ – is the new future of laser remote welding.

Leisurely the robot’s arm slides over the rough car body. Out of his arms he dashes, just like Zeus dozens of flashes per second, which land ostensively aimless on the components which are supposed to be joint. Where they impinge a welding spot is set. This system is at least ten times as fast as today’s welding robots.”

reports Yahoo!Finances (2005). The author talks about the so called Laser Remote Welding, where the welding is done by a laser from afar. The highly energetic laser beam is proceeded by a moveable mirror on the surface of the work piece. By that the working plane is stretched. The height can be shifted by an additional moveable optical system. Within the so gained operating distance the laser can be shifted with a very high dynamic and the components be welded. In comparison with a traditional laser remote technique the dynamic can be increased relevantly, by the sole movement of a scanner mirror with its relatively slight mass.

In combination with a robot the so called welding-on-the-fly renders possible. While he moves conveniently on his course the whole area beneath him is being handled.

The essential advantage of the system links in the reduce of non-productive process times and a very high quality of the welded joints. By the high dynamic in shifting the scanner mirror the time needed to proceed from the end of one welded joint to the beginning of the next one is negligible short.

The laser is being fed by an optical fibre and thus renders possible a very high flexibility. The optics can by the help of the robot be swung in range and hence are independent from the position of the welded joint and the components which are to be handled.
