Exact focus control for high-quality welding results

Optimum focusing of the laser on the workpiece is crucial for high-quality laser welding results. Detuning the workpiece from its ideal axial position – whether through workpiece tolerances, non-ideal clamping devices, or other positioning inaccuracies – impacts welding quality. To prevent such focus-related welding failures, FocusFinder monitors the axial position of the workpiece and ensures exact focus control and positioning through the collinearity of the probe and laser beams.

FocusFinder

Advantages

  • Better quality output

    Any parts with welding failures can be identified and rejected
  • Minimal impact on process time

    The collinearity of the laser beam and FocusFinder light beam ensures no shadowing and eliminates the need for additional movement
  • Optimized welding process 

    Non-ideal clamping devices can be exchanged, workpiece tolerances identified, and the z position optimized. Moreover, waste is reduced as the focus can be adjusted before welding
  • Easy integration

    FocusFinder can be easily integrated into welding machines and combined with Precitecs Laser Welding Monitor (LWM)

Technical data

  • Measurements/second: up to 60 Hz
  • Axial measuring range: 10 mm (depends on focussing optics of welding machine)
  • Accuracy: ± 50 µm 
  • Spot Diameter: 400 µm (depends on focusing optics of welding machine)
