Embodiment Construction
[0054] according to figure 1 The connecting device is a laser beam welding device with remote-controlled laser processing optics; the processing beam is thus a laser. The laser beam production unit 1 generates a laser beam 2 which is aimed by an aiming unit 3 movable along the beam axis onto a deflection unit 4 a oscillating about its respective transverse axis and a deflection unit 4 b oscillating about its longitudinal axis. The focusing unit 5 finally produces a laser burn spot 8 on the surfaces of the workpieces 6 (upper plate) and 7 (lower plate), which burns at a feed speed V s Move along the connection junction.
[0055] The projection device 10 projects a beam of light perpendicular to the joining point onto the workpiece surface with the measuring beam 11 . The sensor 13 detects the light, wherein the sensor focusing unit 12 can be connected in series at the front end of the sensor 13 . The evaluation and regulation unit 15 connected to the sensor thus calculates t...
