Joint geometry
Keep the line visible across edges, gaps and changes in surface angle.
Inspect, measure and process · Industry, inspection & flow
Weld seam tracking & positioning
Locate the joint with a camera-visible reference line.
Application focusJoint geometry
Process background
Choose wavelength and filtering around the camera and welding emission.
Timing & placement
Keep exposure, mounting and robot motion consistent.
Why the source matters
The projected line reveals joint edges and height changes so a vision system can estimate the seam position before or beside the welding process.
The correct source is defined at the sample or process—not at the laser aperture. Wavelength and operating mode set the interaction; stability, delivery, timing, and control determine whether it stays useful in the complete system.

Application workflow
Design from the result backward.
Three decisions turn the application into a practical source specification.
Position the measurement
Define whether the line is viewed ahead of, beside or after the weld. Check camera visibility, joint geometry, standoff and mechanical clearance.
Establish optical contrast
Test the actual material and process background. Select wavelength, camera bandpass filter, line width and power together to avoid glare and saturated pixels.
Validate tracking in the cell
Synchronize modulation and camera exposure, protect the window from spatter, and verify the estimated seam position through the required robot motion.
Selection guide
Match the architecture to the experiment.
These are starting architectures. Precisometer qualifies the final wavelength, output, delivery, control, and integration package against your setup.
- Wavelength band
- Visible or near-infrared line projection, selected around process background and camera response
- Operating mode
- CW or camera-synchronized modulation
Visible-line positioning
Consider MDL-III or the visible wavelength configurations of MDL-XF-A, then verify camera contrast on the joint.
Near-infrared inspection
MDL-H and MDL-DF-808 provide near-infrared options. Match detector sensitivity and filtering before selecting power.
Robot integration
MDL-XR-Line reduces separate driver packaging. Confirm control signals, cooling, protective windows and the required enclosure.
