Welding automation

Automated welding processes make welding operations faster and more repeatable. The top priority here is maximum productivity along with consistent quality. In modern spot welding, additive welding processes and robot welding, all process steps are clocked and carried out with the highest precision. In this respect, high precision sensors from Micro-Epsilon impress in numerous measurement tasks and are used, e.g., for control, intensity control and weld path planning.

3D component scan before laser cladding

With laser cladding, the component surface is melted by a laser beam and joined to form a new, pore-free layer by the addition of a powdered filler material. Prior to laser processing, the components are scanned with a scanCONTROL laser scanner…
