Creating a reference program
Safety
General A low-power pilot laser is required for this work.
A reference program must be created:
-
After fitting the laser welding head for the first time
- When programming a new component, provided that the x and y values on the adjust-
ment units have changed.
Creating a refer-
ence program A metal gauge for precise positioning of the wire electrode relative to the focal spot of the
laser is included as part of the laser welding head scope of supply.
This gauge is fitted within the operating range of the robot and is used to create a reference
program for series components.
Create a reference program before welding the first series component
Requirement:
-
The laser welding head must be assembled and fully connected.
- The wire electrodes must be threaded in.
- A stick out of 18 mm must be set for the lead electrode.
Fit the gauge (1) within the operating range of the robot
Switch on the pilot laser
Position the laser welding head via the robot so that the laser optics are at an angle of
90° relative to the gauge
Presets for finding parameters for the com-
ponent to the welded:
Move the robot towards the gauge so
that the focal spot of the laser is within
the crosshairs on the gauge
Lower the laser welding head using the
robot so that the lead electrode is
touching the gauge
Use the x and y adjustment units on the
laser welding head to position the lead
wire electrode in relation to the focal
spot of the laser
Standard value:
r = 3 mm
Both wire electrodes should be
touching the gauge.
Document the gap between the lead wire electrode and the focal spot of the laser
along both the x- and y-axes as per the scale marked on the gauge
WARNING! Work that is carried out incorrectly can cause serious injury and dam-
age. Set up work must only be performed by trained and qualified personnel. Ob-
serve the safety regulations in the operating instructions, paying particular
attention to the section entitled "Safety inspection".
