The problem

Manual pickling cannot keep pace
with structured production

When volumes grow, manual pickling becomes a costly problem.

Inconsistent results from one operator to the next, continuous consumption of chemical products, scrap and waste to dispose of.

And times that slow down the entire production flow.

Delivering quality and quantity together requires a repeatable process.

The solution

The laser cleans, pickles and passivates.
With no chemistry.

The Laser Weld Cleaner removes weld oxides, rust and contamination from stainless steel using a laser beam.

No acids, no contact, no liquids to dispose of or manage. The beam acts only on the layer to be removed and leaves the metal underneath intact, with no abrasion and no deformation of the part.

On the weld seam, the laser does the work of true pickling: it removes the weld oxides and free iron that trigger corrosion and restores the corrosion resistance of the stainless steel. No chemical preparation, no dwell time.

  • No acids or liquidsno chemistry to manage, nothing to dispose of
  • No contactno scratching, no deformation, no thinning of the metal
  • No consumables to purchaseor liquids to dispose of

Versatility

One machine, multiple applications

The laser does not stop at weld cleaning.

The same tool covers multiple operations on stainless steel and beyond.

The proof

Verified passivation,
not just visually clean

Stainless steel weld seam, laser-pickled

A weld that looks clean is not necessarily pickled. We had the results verified by an independent laboratory, to international ASTM standards.

  • Free iron (Ferroxyl, ASTM A380/A967)No trace of free iron on laser-pickled welds. Free iron is the contamination that causes stainless steel to rust.
  • Polarisation curves (ASTM G61)Laser-pickled welds show passivated behaviour.
  • Salt spray (ASTM B117, 240 hours)Overall good corrosion behaviour on laser-pickled welds.
Automation

Integrated on a robot
or built to order

The Laser Weld Cleaner is not only for high volumes. It also delivers excellent results on complex or specialised operations, where the outcome must remain consistent.

It mounts on cobots and integrates into automated processes. With over 30 years of experience in stainless steel, we also build custom solutions based on your specific requirements.

Machine vision analyses the cleaning result, compares it against a preset quality model and repeats the process until the finish meets the required standard.

Consistent, repeatable results at scale, with no dependence on the individual operator.
