The Next Paradigm in Laser Welding
The Tech
Our patented imaging technique is the only technology that delivers direct, geometric measurements of laser weld penetration—during the weld. Inline Coherent Imaging, or ICI, uses a low-power IR laser beam to gauge distances. This measurement beam is fired through the same optics as the welding beam, getting right to the bottom of the vapour channel and returning the actual penetration in real time. The resulting data is equivalent to a lengthwise section of the weld, delivered instantly, with no additional labour and without destroying the part.
ICI is flexible, with applications in a range of laser processes beyond welding, and the ability to measure a growing number of process-specific metrics. ICI-based seam tracking, height following, and surface inspection are just a few examples.

OmniWELD
Four measurement streams. One welding pass. One instrument.
LDD’s OmniWELD is the most comprehensive laser weld monitoring solution on the market. Combine multiple measurement streams for automated PASS/FAIL and closed-loop control, as the application dictates. Know your process in unprecedented detail, and take the guesswork out of quality assurance.
Keyhole Depth
It’s in our name. Reduce or eliminate destructive tests. Keep a detailed record of every production weld. Actively control weld depth.
Seam Postion
Follow the right path. Trace the seam position ahead of the weld to catch errors in fit-up. Adjust the laser path on the fly to keep welds on-target.
Workpiece Height
Stay in focus. Detect changes in material height that can bring your process out of spec. Control head offset to correct for warp and runout.
Weld Surface
Verify the results. Scan the finished weld seam to flag surface defects like pits, underfill, and spatter.
Sectors
Our broad expertise allows us to deliver flexible and effective solutions to end users in production, process development, and R&D. Our customers rely on our technology to help them excel in a variety of industries.
