In space, metals can weld together without heat or melting.

do the crystal structure of metal needed to be the same?

Remember to put on your welding mask at 0:09

man i love your channel. Thanks for this.

Sooooo NASA fanboy! You have been asked to reinforce the fakery of scientism agenda! Here is how selling out will cost you a LOT in a very near future. A future where people like you are going to be disregarded and discredited so harshly I will even feel bad. If it is intentional like Vsauce, we will know, if it is because of your lack of education and ability to understand the realm we live in then you still have a small window and come around explaining why this video along with other ones are pure propaganda and does not have any tangible content.
Time will tell -
I never heard of cold welding before. I know on earth Tungsten usually doesn't like sticking to other metals so I wonder if that would be a good one to use on space craft.
How big can we use cold welding? can 2 metal ingots be cold welded together? can we weld space crafts or stations using cold welding? -
I understand why objects of different materials or alloys won't 'cold weld', but why won't materials other than metal fuse together is space? If you have two identical pieces of plastic, what about plastic, keeps them from sticking together? Plastic is just one example, you can insert other items in it's place, but the question remains.

Gave us those cold welding tips like were going to be using them
-
I thought the title said space weed, whoops

Stupidest explanation EVER. CANDY BARS?
-
This is cool and all, but I clicked this vid to see the canadarm do some stick welding
-
Those candy bars look delicious.
-
I hate those peanuts it's freaking hard and often hurt me when i'm smashing it in my mouth .
-
Hey, that's a Payday bar. I love those.
-
Could cold-welding ever be utilized on a scale larger than the nano?
-
Doe s anyone know what this guy does for work, in real life, outside of youtube?
-
i know that your house, and you have poor taste in kitchen decore
-
real life kerbals

The problem is with similar metals that slide past one another (solar panels, antenna, etc.), thereby scraping the oxide layer away.
-
What really happened is the cold in space shrank the metals and caused them to bind, nothing to do with cold welding, cold welding is welding without full penetration, e.g get two tight fitting steel tubes and put the outer one in fridge then slide into the smaller one, it won't work
