Adjustment work on the welding head
5-41
Focus search with machines without
AutoLas Plus
Only an approximate search is carried out on machines that do not
have AutoLas Plus. The Deviation from nominal dimension is
determined. The length of the welding nozzle is adjusted to the
new nominal dimension, after which a monitoring of the results of
the approximate search is carried out.
The focus position f=0 is determined in the welding-through
process. The Deviation from nominal dimension parameter is
determined.
The CP_FOCUS_WELD program is used to weld eleven 40 mm
welding seams, each with a different focus position. After each
weld seam, the nozzle distance is increased by 1 mm. The process
starts with a nozzle distance of 10 mm.
Prerequisite
•
The welding head is fully mounted.
•
A nominal dimension of 4 mm is set at the welding head or a
sleeve with a nominal dimension of 11.5 mm is utilized.
•
The beam is centered.
•
Clean nozzle in mint condition
Additional equipment, tools, material
•
A flat, oil-free, 4 mm thick sheet, 600 mm x 150 mm, St37.
•
Gauge block 10 mm and 15 mm.
•
Utility program CP_FOCUS_WELD.
Note
The sheet must lie completely flat on the support and is not
permitted to warp during the welding sequence (the sheet should
possibly be tightened).
1. Select >Operation >Set-up > Service.
2. Set the "Head change" switch element to ACTIVE.
The selection dialog is started.
3. Work through selection dialog for mounted welding optics.
4. Select >Operation >Set-up >MDA.
5. Enter B0 C0.
6. Press Start.
The B and C axes travel to 0°.
7. Position the welding head 10 mm over a flat sheet. Use a
gauge block to check.
8. Note absolute position of the Z axis.
