Signal sequence for LaserHybrid welding
Safety
WARNING!
Work that is carried out incorrectly can cause serious injury or damage.
The welding sequence must only be programmed by trained specialist personnel. Observe
the safety rules in the operating instructions, paying particular attention to the section en-
titled "Safety inspection".
CAUTION!
Risk of damage to optical fibre if laser welding head is positioned perpendicular to
the surface of the workpiece during welding.
If the laser optics system is placed at a right angle to the surface of the workpiece, the laser
will be reflected directly into the laser optics system. The optical fibre can be seriously dam-
aged if this occurs.
Always set the laser welding head at a forwards or backwards tilt angle.
NOTE!
When welding a number of short weld seams one after the other, do not switch off
the crossjet flow and external extraction until the end of the entire sequence.
This will prevent welding smoke from making the protective glass dirty.
Signal sequence
for LaserHybrid
welding
Robot start position:
Set the "extraction on" signal
Set the "crossjet on" signal
Select the mode
e.g. mode "3" (internal parameter selection for adjustment purposes):
set mode bit "0" to "1"
set mode bit "1" to "1"
set mode bit "2" to "0"
If "Job" mode is selected, see the operating instructions for the MIG/MAG power
source for more detailed information about this mode.
If preheating is not required, continue from "LaserHybrid welding start position".
Preheating start position:
Requirement: the laser must be ready to enable the beam.
Set the "gas test" signal
Set the "laser on" signal
The preheating temperature comes from the following factors:
travel speed,
laser power,
distance to the surface of the workpiece
