Automatic welding of gratings


  • No need for expensive clamping devices and processes, approximate positioning ± 1 00 mm is sufficient
  • No CAD model necessary
  • Highest efficiency with minimal downtime
  • No teaching / no offline programming
  • Suitable for workpieces made of steel and stainless steel
  • Accuracy of up to 0.1 mm
  • Automatic welding path calculation in a matter of seconds


Scanning the object

Comparison to the CAD

Determening the processing location

1. Rough localisation

of the components using 3D overview camera. The position of the component is largely arbitrary.

2. Path calculation

for the scanning process, based on the 3D overview image.

3. Fine scanning

of the component, using a 3D laser scanner mounted on the robot, for accuracy up to 0.1 mm.

4. Welding path calculation (Variante A)

by comparing with a CAD file with defined welding points and -parameter.

4. Welding path calculation (Variante B)

by defining rules (e.g. circles Ø 10 – 60 mm).

5. Welding

of the component along the automatically defined welding path.
