What am I looking at here? I understand Additive Manufacturing. Thia appears to be a process "welding" new material to the base, but where is the new material coming from?

I think it is an AI generated videoQuote:

We are all in trouble.
IF it is AI generated, which as Frank mentioned I tend to believe, then one of our common ways to search for the truth is very compromised. I tried an image search to see if I could get more information. I put this screen shot into the Google Image Search.

Before I got my finger off the "send" button, I got this AI generated response;
The image shows a process known as laser hardening, also referred to as laser heat treating. This is a method used to increase the hardness of a specific area on a metal part.
A high-powered laser beam is focused on the surface of the metal, rapidly heating it.
The surrounding, unheated metal acts as a heat sink, causing the heated area to cool down quickly once the laser moves away.
This rapid cooling, or quenching, changes the microstructure of the metal, making the treated area harder and more resistant to wear.
This process is particularly useful for hardening specific sections of a large component without heating the entire part, which helps to minimize distortion.
This is a real process, and correctly described. The image clearly shows material being added to the surface. So here we have an example of AI using itself to validate a fake image.
I then asked AI if the image was AI generated. The response;
The image appears to be a real photograph. It shows a close-up of a high-speed train brake disc during a braking test, where the friction has caused a section of the disc to become incandescent due to intense heat. The glowing orange line is a result of this extreme heat.
In first response, AI said it was a process. The second response AI said it is a test.
I believe this is a real video of laser hardening.

At first glance I agree with Frank that its AI generated. Then after watching it several times I noticed the ridge shadow line at the upper edge of the laser beam disappears as it rotates?...as I'm not sure it is rotating in a chuck as the chuck doesn't seem to moveż...or the laser is rotating. Then I manually slid the playback button backwards slowly and it looks more like additive manufacturing.
We've seen a lot of these mirrored gifs here on HMT but they also indicate some form of fakery. Additive manufacturing means adding material like a 3D printer starting from a base and adding material. Rolls Royce pioneered this way back on some of their aircraft engine turbines blades. However there is subtractive manufacturing as well, basically in CNC, lathe, mills etc. but sometimes done with Lasers.
That said I'm not discounting hemmjo's observation and in-depth rabbit holing, of being laser surface hardening...but the one thing that typically happens is the material has a bluish tinge after the laser passes by. I just don't see that in this video.
My gut still tells me something is off with this Gif! As in the laser or chuck being rotated?, or sliding the playbar backwards slowly make a case for additive but not seeing where the additional material is coming from and no splatter...and then there is the disappearing shadow at the top of the beam??
Who's Knows...Only the Shadow Knows.
Another thing leaning toward subtractive manufacturing are the threaded hole lands that go the laser area are partially missing on the 12 O'clock hole...as it rotates in the chuck (you can see the background change) toward the second threaded hole the land exists on it! My bet as the laser goes by the 2nd hole it will remove the land.
Over all it's very misleading title and confusing videography...Gifization of stills and my bet goes back to Frank...it's AI fakery. Ad Nauseam, adhuc nullum pax.
