Signal Sequence for LaserHybrid Welding
Safety
Signal Sequence
for LaserHybrid
Welding Robot start position:
Set signal "Extraction on"
Set signal "Crossjet on"
If preheating is not required, continue from "LaserHybrid welding start position."
Preheating start position:
Requirement: The laser must be ready for beam release.
Set signal "Gas test"
Set signal "Laser on"
The following factors determine the preheating temperature:
Travel speed
Laser output
Distance to the workpiece surface
Preheating end position:
Reset signal "Laser on"
Reset signal "Gas test"
LaserHybrid welding start position:
Requirement: The laser must be ready for beam release.
Set signal "Arc on"
Wait for the current flow signal ("arc standing")
Set signal "Laser on"
Set signal "Start robot"
WARNING! Work performed incorrectly can cause serious injury and damage to
property. The welding process may only be programmed by trained personnel.
Please observe the safety rules in the Operating Instructions, and the "Safety In-
spection" section in particular.
CAUTION! Risk of damage to the fiber optic when workpiece surface is posi-
tioned at a right angle to the laser welding head in welding mode.
If the laser optics are at a 90° angle to the workpiece surface, the laser radiation
is reflected directly into the laser optics. This can cause serious damage to the
fiber optic.
The wirefeed to the laser welding head should always be leading or trailing.
NOTE! When welding many short weld seams in immediate succession, wait until
the end of the entire sequence before switching off the crossjet stream and exter-
nal extraction. Doing this you will avoid contaminating the protective glass with
the welding fumes.
