|
Sensor
controlled welding robot for straight and curved seams.
|

 |
| |
• constantly
high weldseam quality
• simple handling, programmable
• override, to optimize parameters
• automatically stop at end of seam
Continuous recorded data:
• weldseam width, weldseam depth, weldseam center
• flank angle, root layer

The
MEL-Laser-BUG is an association
development of BUGO systems, Pittsburgh, U.S.A. and MEL Mikroelektronik,
Eching, Germany. Bugo systems delivered the guideway system and the drive
assembly; MEL contributed the scanner system and the software.

The
Laser-BUG is made ready for all joint geometries. By choice of a work
program (additional parameter adjustments are enabled) the welding robot
can be adapted quickly to a new task. The LCD display shows the course
of the joint and the current parameters of the power transmission.
The laser scanner takes the position control of the welding tip and the
pendulum drive.
The parameters, as pendulum width, pendulum speed or feed rate are alterable
during welding process.
To toggle manual and automatic navigation is possible at any time without
interruption.

The
Laser-BUG is working totally independent of position. Application software
for fillet weld and butt weld are already preset ex factory. Further own
routines can be simply added by "teach-in". On the first weld
cycle, the laser scanner saves the complete geometry of the weldseam.
Whenever required, the course - including parameters - can be retraced
"from memory".

As
sensor, a M2DW with cooling plate
is applied. This sensor can stand temperatures up to 500°C (932°F)
and does not include any mechanically operating parts. For the tough
use under welding conditions, this unit is most suitable. Welding splatters
and smoke during welding process do not interfere this optical sensor.
Mirror-like or rusty sheet metal, cut smooth or fray seam borders are
measured without problems.

Optional, for the welding of
tanks on turning devices, there is a version with cross slide available.
For over 20 years, MEL is the most innovative producer
of intelligent sensors. Worldwide there are several thousand laser scanners
in action. Take advantage of our experience.
We solve problems of measurement and sensor technology. For it, we build
hard- and software as turnkey solution.
