OmniWELD

Four measurement streams. One welding pass. One instrument.

OmniWELD

LDD’s OmniWELD is the most comprehensive laser weld monitoring solution on the market. OmniWeld combines four different ICI measurement modes into a single simultaneous monitoring operation. The result is a single-instrument process monitoring suite that offers unprecedented versatility while allowing rapid customization. A single LD-600 running in OmniWELD mode can replace multiple existing measurement technologies and provide LDD’s industry-first penetration monitoring—at the same time.

Our multi-factor monitoring seeks out defects before, during, and after the weld process. The exact combination of pass/fail and control for each measurement stream is rapidly configured in software. You can create a tailored monitoring scheme for your process that has all the information you want, and none that you don’t.

Seam Position

A measurement sweep ahead of the process looks for joints or edges on the workpiece and returns the offset between the actual position and the target weld path in real time.

  • Human-readable image output
  • Automated PASS/FAIL based on mechanical tolerances
  • Active control signal for seam following*

Workpiece Height

A measurement just outside the melt pool looks at the distance between material surface and the welding optics and returns the offset from the desired focal distance in real time.

  • Human-readable image output
  • Automated PASS/FAIL based on mechanical tolerances
  • Active control signal for autofocus*

Keyhole Depth

Depth measurements from inside the keyhole return the actual weld penetration in real time.

  • Human-readable image output
  • Automated PASS/FAIL based on mechanical tolerances
  • Active weld depth control†

Weld Surface

Trailing measurements just behind the melt pool capture a profile of the finished weld bead immediately after it solidifies, catching surface defects right after they form.

  • Human-readable image output
  • Automated PASS/FAIL based on mechanical tolerances

* when combined with a motion control system capable of reacting to the control signal
