Laser Rust Remover / Laser Cleaner

[jayysann]

Hello, I'm a newcomer, and wanted to ask about the technology I'd seen in this video:



There are videos up to 10 years old on Youtube on this particular technology.
From what I've seen, it seems to be quite miraculous for cleaning and restoring rusted metal components.

Now that the patent for this technology has expired, there seem to be various companies coming out with cheaper machines for the market:

But the pricing still seems quite expensive. I wanted to know if a laser-engraver machine could be modified/adapted for this type of application.

If so, then what would it take to accomplish this?

Yes, you can use a small fiber laser marker to do laser cleaning. I did a job where I removed titanium oxide from metal batteries to be used within a medical device, with a 10 watt fiber laser marker. The fiber laser markers can remove very thin coatings, but for heavy duty rust like your photo, it takes too long and more power, so you really need about 200+ watts of a fiber laser with a high peak power. It has to Q-switch to an extreme peak power that vaporizes the surface, yet does not penetrate the substrate (metal). The glass tube CO2 lasers are a different type of operation where they use continuous wave (no peak powers), so they will not work or they will sort of work, but heat up the underlying metal so much, that it can cause heat damage or some other type of damage. You can remove paints with the CO2 glass tube laser, but again, it really heats up the underlying metal, so not advised.

Hi bro,
It's not feasible to modify the laser engraver for cleaning rust. Now the price of laser cleaning machine is cheaper than before. And the cleaning effect is better. If you still have any interests of laser cleaning, please contact me at any time.
