Collision Protection
General The laser welding head is fitted with collision protection to protect the LaserHybrid welding
torch and the entire laser welding head.
The collision protection works on the floating contact principle. Displacing the welding torch
a certain amount will open the circuit (ring line) between the two inputs for the robot control.
The ring line runs from the laser welding head, via the LaserHybrid hosepack, on to the
SplitBox SB 360i LaserHybrid, and from there on to the connection for the robot interface
used on the power source.
Safety
Checking the Ref-
erence Point after
a Collision IMPORTANT! After a collision, check the reference point as follows:
Set a 14 / 20 mm stick out on the LaserHybrid welding torch depending on the appli-
cation and design
Move to reference point
Using the gauge, check the position of the wire electrode in relation to the focal point
in the x/y/z direction
Further information can be found on page 94.
Signal Analysis The signal from the collision protection is sent to the robot control via a robot interface.
In the event of a collision, the ring line will open and the signal level will drop. The robot
control must carry out the following program sequence:
-
Stop the laser and arc welding process immediately
- Stop the robot movement immediately
WARNING! The collision protection and its digital analysis are not a substitute for
an electromechanical emergency stop protection device. Just like with collision
protection, the emergency stop protection device also has to shut off the arc pro-
cess and the laser process.
