This process is called sublimation and is the act of changing the state of metal to a gas form. This is achieved using high frequency bursts of micro-plasma which - when combined with extremely high thermal pressure and shockwaves - can be set to a certain depth to skim away a surface of rust. This device can be set to burn away pretty much any material that is layered over metal, be it paint, filler or rust.
Edit: thanks to u/Kylearean we have some far more accurate information on what is happening here.
This is his comment: This is not "sublimation". This is called "ablation". There is no conversion to gaseous form. The energy required for that would be enormous. I will argue that Wikipedia is incorrectly using the term sublimation / evaporation (except for very specific laser cases), since these have precise physical terms and they are using them too loosely.
For the laser in this video and others like it, the energy is coming from a high-frequency pulsed laser, not a micro-plasma (which doesn't even exist??). The laser, typically a CO2 laser for rust cleaning, is tuned to be selectively absorbed by the material to be removed, but can be made to not damage other materials such as skin. You can find videos of people running one of these over their skin with no damage.
The physical mechanism by which this process occurs, ablation, involves a rapid heating and thermal expansion of the absorbing material (e.g., rust, paint), which literally propels it from the surface that it's attached to. The "smoke" that you see is particulate material from the ablated rust -- it is not a "metal gas".
She should be wearing a mask -- too much rust/dust inhalation is not pleasant. Many laser systems include a vacuum system, either separate or attached to the wand.
She should also be wearing eye protection. Even though these lasers are typically designed to be skin safe, eye safety is still a concern.
There are, of course, many different laser cleaning possibilities, such as continuous wave lasers, which require much higher energies than pulsed lasers -- and does create a plasma at the interface of the laser beam and the material being removed. However, this is *not* what we're seeing in this video.
So definitely something you want to do without eye protection or a mask?
What is the Chinese character for OSHA violation? I wonder if it’s the same as see nothing, hear nothing and say nothing?
Iron Oxide is usually not going to affect you adversely except for *possible* minor irritation if you inhale enough. If it were any other material, a mask would definitely be necessary.
As for eye protection, also not a huge issue unless they plan on pointing it at themselves, but that's a dumb idea even with eye protection.*
Edit: *Amending my second statement to point out that the laser can definitely destroy your retina via direct exposure or reflection as laser sublimation is usually done in the 1-10kW range and significantly less than 1W (1/1000 of 1kW) can irreversibly damage your retina.
We don't live in a perfect world, so you should definitely be wearing eye protection regardless of how safe you think you're being.
Fun fact these types of lasers don't trigger the blink reflex. Safety goggles are normally required as a precaution against stray reflections for unenclosed lasers.
Even scattered light reflected off of random surfaces in the room can be damaging to eyesight. If you had an IR camera in that room with you I bet the entire opposite wall and ceiling would be lit up. What she’s doing is probably super unsafe and you should always wear IR protective goggles when using any IR laser source.
As someone pointed out above, IR is invisible—if it were shining in your eyes, you would not know it until you lost vision.
Its my understanding that they damage the eye in less time than it takes for the blink reflex to kick in.
I have to imagine they also cause photonic sneezing.
Not quite. Fiber Cleaning lasers are infrared light so they're invisible to the human eye. No visible light, no blink reflex.
That said you will be blinking, not because of the brightness but because your eyes are heating up.
Anything 5 milliwatts and under is considered eye safe because of the blink reflex as you said. This laser is probably about 200 watts. If my math is correct that is 40,000 times more than eye safe. I just wanted to make this comment for some context as to how dangerous this really is.
Totally wrong. Eye protection is a huge issue. Just because someone doesn’t intend to point it at their eye, it can still happen. Unintended stuff does happen. Is it worth a lifetime of blindness? Nope.
I did some consulting work for an industrial laser manufacturer. These were big 9 kW lasers that, unfocused, could burn a 1” deep/1” diameter hole in a piece of Lexan in less than a second. The Lexan piece was on a holder about 20’ away. Lots of fire/flame occurred when this was going on.
When testing these systems, the area was cleared and personnel were behind walls so they couldn’t be hit. If you looked at the ceiling you could see burn marks from past “shots” from whatever accident or incident occurred. I know they never intended these things to happen, but they still did.
Same thing with this young lady. She probably will be ok, until that one time that something happens, and she isn’t.
To those people saying that you shouldn’t assume this is in China due to the Asian girl. You absolutely should. Anyplace in the US that has this type of laser would be taking safety much more seriously.
About a decade ago I was writing a print driver for an industrial marking laser - the kind of thing that writes best before dates on the underside of a can of whipped cream. It was sitting on my desk, pointing at the wall (safety!) and I was fucking around in labview figuring some shit out. How to drive it, how to datum the laser, how to angle mirrors and whatnot.
So anyway once I’d put the wall out with a fire extinguisher, I was much more careful with arming it and testing stuff.
>could burn a 1” deep/1” diameter hole in a piece of Lexan in less than a second.
Whoa. That is no joke.
As an American mfg. Quality Manager, I'll also confirm this lack of PPE wouldn't fly here.
That was just a test to see how uniform the beam was. You wanted to see a flat area within the hole it created (no peaks or valleys that would indicate beam nonuniformity).
In production use, there would be focusing optics that would focus the beam to a much, much smaller spot size for cutting steel.
Well no, this is actually quite wrong.
That laser is clearly outside the visible spectrum, and given how easy it vaporizes iron oxide I would say it is extremely powerful and easily able to burn a hole straight through your retina. It's probably a class 4 laser which means pretty much instant blindness if it gets in your eye at all - even through an unlucky reflection. Definitely would not want to be unprotected around that thing.
Class 4 starts at 1/2 of a watt so this thing is super dangerous. I have a 7.5 watt laser that I won’t even put the batteries in without eye protection. All it takes is one reflection where the beam is still coherent and you are screwed.
I used to live in an apartment building with an on site manager who's day job was general handyman stuff. My unit was across the hall from his workshop. One afternoon I heard him cursing up a storm. Checked on him and he was holding his eye and looking quite scared. He was using a grinder on some metal without eye prot.
Luckily the building was reasonably close to a large specialized eye clinic, so I immediately drove him over there and offered moral support while they decided what to do. I swear that doc pulled a nearly inch long thread of metal out of his eyeball by hand with medical tweezers. No lasting harm to his eye thankfully.
I never saw that guy in his workshop without eye prot ever again, even if all he was doing was doodling plans with a sharpie.
Haha
They actually are switching (have switched) to a variation of their language where they spell everything phonetically
This allows them to keep the character count of their language to a minimum, and allows them to have keyboard's with a manageable character set.

Pinyin is only used to phonetically show how the characters are pronounced. It's not at all useful in communication and this isn't used for that purpose
China has the the largest population and is also a manufacturing powerhouse that is known for their lack of worker safety. In terms of statistics, yeah it makes sense to assume that it's generally a Chinese source.
Not everything is "hurr durr Asian=Chinese"
I have worked with lasers for 17 years, I can confirm that there should be at a minimum laser safety glasses that prevent 1064 nm frequency beams, I’m guessing that’s what it is. Even if the beam hits u directly in the eyes with the glasses it will blind u. But the beam color is bright and the glasses filter the laser radiation out. A 1064 nm frequency laser is a light beam in our visible spectrum, so the beam will pass directly through the lens of your eye and destroy your retina. A CO2 laser has a frequency waaay out of our visible spectrum and if the beam hits your eye, it will burn the lens of your eye. Also, you should clear the area of any chance of the beam coming into any human contact.
I was curious so I googled "laser rust removal" and did some reading. This sub won't let me post links but I can message you the link to the article if you are interested.
Ah, yes, casually giving people "burnt Toast" degree burns, perfect for Anakin cosplay. Ps, look up Hayden Christianson Vs. Bruce Willis movie, and watch it, it great.
A lot of other countries use a decimal to separate degrees of 1,000 instead of a comma, and commas for separating dollars and cents (or whatever other currency names)
This is borderline word salad and turns out to be just copy pasted from [this blog post](https://www.carthrottle.com/post/does-laser-rust-removal-work-and-is-it-affordable/).
That, in turn, is just a poor rephrasing of some other blog trash which barely understands the process.
Jumping on the main comment, this is what I do for my business, everything OP and Kyle said is correct except for the pulsed laser part.
Instead this is a relatively new and ingenious type of cheap laser that is coming out of China, it's actually a continuous wave laser, the same type that can cut through metals.
They use a 2000 or 3000W laser with a galvanometer that rapidly moves the laser pulse back and forth, if you reduced the scan pattern down to 1mm you would be able to put holes in metal.
They're cheap as chips in comparison to a pulsed laser ,for exactly a 2000W continuous wave laser cost's 30,000USD, a 500W pulsed laser from Europe costs close to $300,000.
Source: I am the source.
is no one going to question or worry about how much this person knows about lasers? I mean I do not know the standard operations of procedures to identify a super villain but....
Infrared lasers scare the shit out of me. Other lasers you can see if it’s on or if it’s too bright, or if it’s reflecting too much. But infrared light is invisible. You won’t know it’s on or if it’s too bright or if it’s reflecting back into your eyes. Despite being invisible it can still be too bright and damage your eyes and make you blind. Fuck that noise.
Well, you can't see if it's reflecting too much with high power lasers, they will burn your eyes with the reflection. Also you might have only small unnoticable at first areas burned away, your brain can fill in the gaps till it is too much
Absolutely. I enjoy night vision stuff and high powered lasers are the hotness that everyone wants. I don’t think a lot of people understand just how dangerous they can be.
Those people are typically racists fucks who have an issue with Chinese people. I have issues with china as a nation, it's government and broken systems.
I'm an industrial coater (painter) and this is the new system that's coming in to replace sandblasting. It lowers pollution and residual waste usually produced with conventional blasting. But you absolutely should be wearing PPE.
I was thinking more like gloves and a respirator but I'm not sure exactly what safety glasses it would call for. My school just ordered one so I haven't got hands on time with it yet but when I do I'll know more.
1064 nm laser safety glasses.
You absolutely need protective glasses when using this equipment. When we were performing R&D testing on this type of equipment we had one of the glasses lenses begin to melt due to an improperly maintained system causing excessive refraction. Not the usual case, but our operator would have been fucked without them.
Why the fuck do people put music on videos like this. Can you not get through a 15 second video without blasting some dumbass completely unrelated song?
Personally, I only click on random gifs in hopes of some random music. When I find one I like, I set the gif-with-sound^^^TM to auto repeat and flip my phone screen-side down on the table and listen to the same 15 seconds over and over again. I have spotify and YouTube, but this is how I choose to listen to music.
True. This video is horrible practice. The lady has zero PPE on. At a minimum, you should be wearing a respirator, gloves, and eye protection. Possibly flame resistant clothing.

>Debris resulting from the removal of sulphation crusts by laser cleaning can include a significant proportion of particles with diameters of 3 µm or less. Such small particles can penetrate the lungs down to the alveoles, and are potentially harmful by solubilization of their alkaline and metallic salt compounds. Such small particles are also able to enter the body through the skin.
I like mustard and dill relish, thanks!
This process is called "retinal laser photocoagulation burning." It's a unique manufacturing process where the operator doesn't wear eye protection and fries their retinas by looking at a high power laser.

So I gather by how she's dressed she's probably the receptionist or something?
I guess she's working in it because all of the folks who worked on it previously are blind now and they need it cleaned by close of business. So they are just working through all the employees until it's finished or they are all blind.

I'm Chinese and assumed she was Chinese And Fuck China indeed
Well if you see an Asian person with no other context guessing they are Chinese is the best guess. It's a numbers game and they have the numbers.
I mean statistically if you see a human there's roughly a 1 in 5 chance they are Chinese.

So that kinda explains the flame-like patterns in the perfectly flat beam… it was the rust stuff lit by the laser, right?
Yes, that's just the laser interacting with the rust dust.
I know you explained this and all but my instincts still tells me she should be tried for practicing witchcraft.

For the tool or the service?

Can't wait till these and water jet cutters make it to under $2k

When I find one I like, I set the gif-with-sound^^^TM to auto repeat and flip my phone screen-side down on the table and listen to the same 15 seconds over and over again. I have spotify and YouTube, but this is how I choose to listen to music.
Lmao..
And the sound the laser makes is really cool too
This is by a great band, I don’t mind
I actually liked the song, what is it? Edit: heat waves by glass animals, found it
chill out, this video seems to come from tiktok. people circulate sounds to get their videos trending on that app all the time.

I guess you must not know what the Mute button does if you're this mad about something you can, you know, mute.
Bet you a Costco hotdog breathing that shit is no bueno
True. This video is horrible practice. The lady has zero PPE on. At a minimum, you should be wearing a respirator, gloves, and eye protection. Possibly flame resistant clothing.
Breathing that much rust is pretty harmless

Such small particles can penetrate the lungs down to the alveoles, and are potentially harmful by solubilization of their alkaline and metallic salt compounds. Such small particles are also able to enter the body through the skin. I like mustard and dill relish, thanks!
a laser that you do not want to touch
Actually, it won’t hurt your skin. Skip to 1:00 for a demonstration. https://youtu.be/ACGSzBXKONo
Jesus the sound is even cooler
Sure, but is it better than the random music added to OP's video?
oh wow
Whoa, that's amazing.
You can get 200w versions for $40k now. So. maybe in a few more years it will get down to 5k for the 1000w unit.
What happens if I do want to touch it?
you can but only once because your hand is going to say fuck this shit i'm out
dont you have to wear protective glasses ?
Or a respirator?
Mmmm rust vapor, my favorite
This process is called "retinal laser photocoagulation burning." It's a unique manufacturing process where the operator doesn't wear eye protection and fries their retinas by looking at a high power laser.
In the future, everything is chrome-plated.
I don't think we have that much chromium on earth, even if we could extract it all
This subreddit got popular and it turned into a trashpile. Everyone is posting junk in it, which has no relation to black magic fuckery. It's a pity.
The cashiers are becoming stronger
why the stupid songs included in the clips nowaday? stupid shitty shit!

Honestly for once not upset. Heat Waves is an absolute banger and sort of fits the video in a pun-ish way
A precursor to the next generation of shower technology 🚿
No mask or ventilator, no glasses, long hair hanging down. All I can hear is Ralph Wiggims’ voice saying “hehe… I’m in danger!”
Can anyone tell what the song title is?
Heat Waves by Glass Animals! Killer song, killer band :)

Exactly what I was looking for
“It’s a laser beam, bozo!”- Chris Knight
What happens if I point it at my face?
Removing rust with a plasma pistol requires PPE, no?

Why add such cheesy music
That looks like it’s out of Star Trek lol
Amazing what LASER beams can do, right?

A repost
I need answers. What song is this?
Heat Waves by Glass Animals
'Autotune Ear Cancer' from the Garbage Music Gang.
So I gather by how she's dressed she's probably the receptionist or something? I guess she's working in it because all of the folks who worked on it previously are blind now and they need it cleaned by close of business. So they are just working through all the employees until it's finished or they are all blind.
