Laser derusting machine

Has anybody seen these in action. They look too good to be true but if they work every workshop should have one, The ad and the video show a $44 unit at 1,000 watts. A bit of research has found only commercial units at 50 to 100 watts but at the cost of - wait for it - $25 to 50,000. What am I missing?

SWhere duz the rust go?

Laser cleaning technology works by sending nanosecond-length pulses of laser light towards a surface. When it interacts with contaminants that absorb laser light, the contaminants or coating particles will either turn into a gas or the pressure of the interaction will cause particles to free from the surface.

This article is not a bad description but these people sell half million dollar automatic machines the size of a car.

I also have sen these advertised in different places but never seen one working in person.As pointed out, the ones advertised may not work as well as the bigger stronger ones. Then factor in the cost to run the electrickery through them. Could work out a bit pricey unless you have a lot of solar or windpower generators.
I dont doubt that they would work but the less powerful ones may be fairly slow in working. I thought that ultrasonics for cleaning was a mystery until I bought one for cleaning blinds. When looking at various systems I found that I could buy one rated a bit higher that most and at the same dollars. I since found out the stronger it runs can damage the timber blinds and there coatings.

Just had a look at that video. The rust is new clean lightweight coating as you would get on a sandblasted item left in the rain for a couple of days. A brush with CLR would probably be just as effective. Might be wrong but looks sus to me.

I will try to find something with real rust being treated.

Ps Here is one going great guns, unfortunately it is not $44 but $50,000!!!!!


Here is another many zero dollar unit. Love one comment - "You know this is an expensive tool when the operator is wearing Italian shoes and a suit"

I've seen them advertised on Facebook and it all looks a bit scammy to me.

If the price sounds too good to be true .... You know the rest.

Then factor in the cost to run the electrickery through them

Cobba, The laser is 1000 watts. Less than the missus hair-dyer. But, it's concentrated at a pin point level. Hence the high energy to blow off the crap.

Probably very popular in the gas and oil industries. I did like the idea of cleaning the rust of the threaded bolt.

The clips I've seen have all been showing theem removing paint from the suspension of cars or dirt from the alloy gearboxes etc. No mention of the size, power or cost.

These sound very interesting. I would like to see more information.

Cobbadog Do the ultrasound thingos remove rust? Are they suitable for cleaning up truck suspensions? Without removing them from the vehicle?

IR 365 /..600lb pot and a 3/8 nozzle is what you be needin to remove rust in any meaningful way.
