FD-QT Laser Tracking Sensor

FD-QT

Automatically adjust welding target position during welding

  • Improve Welding Quality
    Detects welding position and gaps, automatically adjust
    torch angle and welding conditions, preventing welding failure.
  • Shorten teaching hours
    Automatically detect welding start point, finish point,
    1 program is able to handle different welding lengths.
  • Easy teaching
    Can be operated by teach pendant.

Visible red laser diode (Wavelength 660 nm)

Classification

Class 3B (Output 120 mW or less)

Dimensions (W × D × H)

192 (W) × 91 (D) × 53.8 (H) mm

Weight

0.89 kg

Working ambient temperature

0–40°C

Working ambient humidity

20–85%RH (No condensation)

Cooling method

Forced air cooling with dried air

(Use in combination with a water-cooled torch and/or high-current welding in narrow grooves may
raise the ambient temperature of the sensor head more than the specified range. In this case, we
suggest the water-cooling option. Ask for pretesting to check if this can work.)

(Dried air (oil and mist-free) is required. When the air contains (oil) mist, use air filters.
Mist in Cooling air can cause the product to malfunction.)

Protection for optics

Air or welding gas purge and disposable lens
