Laser Rust Removal

Laser Rust Removal

(OP)
Has anyone observed this laser rust removal tool?

RE: Laser Rust Removal

It hasn't hit a price point that makes it commercially viable, yet. $150k for a tool that can remove mill scale as well as media blasting or acid dip isn't competitive. It hasn't been demonstrated on the heavy scale experienced in field applications where such a tool would be useful.

Also, with this quote:

"The company explains that the device aims short, 1000-W laser pulses at the rusted piece, producing micro-plasma bursts, along with thermal pressure and shockwaves to sublimate the rust and separate it from the metal without damaging the piece. "

They're looking for fools.

RE: Laser Rust Removal

Google 'laser ablation'; it is indeed a thing.

But as Tugboat says, it is still expensive, so you use it where other methods cannot go. A lot of the expense is the robotic delivery system it can require.

For boilers, carbon dioxide blasting is currently the scale removal method of choice.

RE: Laser Rust Removal

The USAF is using this to remove paint from planes.
- Program the contours once and let the robots do it over and over
- Very good control to prevent surface damage (using wavelengths absorbed by the paint but not Al)
- The only waste is the paint itself which is vacuumed off during the process
It is cost effective with high value assets.
