The hand held rust remove laser
which makes rust literally evaporate.
I could not believe what I was seeing
when I first came across this device on YouTube.
A laser that cleanly removes rust and other surface contaminants
without eating away the metal underneath.
When aimed in the metal surface,
the dirt layer and any oxides underneath will absorb the energy and evaporate.
The metal underneath will not absorb the laser energy,
leaving nothing but a clean surface who ready for welding and painting.
So how does it work?
Well, the system uses short pulses of laser light at a thousand Watts,
producing micro plasma burst along with thermal pressure and shockwaves
to sublimate the rust and separate from the metal without damaging the piece.
Now I know what you’re thinking as I wondered it myself,
and the answer is no.
This will not vaporize human flesh.
Amazingly, aiming the laser at your finger doesn’t even hurt it at all.
Material removal is halted when the laser is applied to a clean surface.
Because it only sublimates rust.
Sublimation is the act of changing the state of metal to a gas form,
skipping the liquid phase.
The device can be set for a certain depth
to skim away surface rust, paint and filler,
leaving a prepared surface for work.
What would have normally taken someone hours to clean
and prepare for welding or painting is now done in no time at all.
What makes this laser device even better is the fact that it has an onboard Hoover system.
That immediately sucks up the vaporize rust,
making the entire rust removal process clean and simple.
Unfortunately there is a rather large drawback-the cost.
This state-of-the-art device is not sitting on some retail shelf somewhere for $100.
The cheapest version on the market is a much smaller less powerful 20 watt unit
that starts at around 80,000 dollars
and a thousand watt unit will set your back nearly a half a million dollars.
So it’s fair to say that laser rush removal is
probably out of the reach of most panel beaters
and mechanics trying to restore cars.
But I recall in the 80s that computer CD Ryder drives
was selling for 50000 dollars
and it was just a few years later that
we were installing them in PCs for under a thousand.
So give it a few years and I bet you’ll be able to buy this device
at your local hardware store for Father’s Day.
Anyway that’s the end of this video.
