Cold welding in outer-space is a hot topic in my inbox. I experimented with gold and stainless steel to see if I could get them to cold weld here on Earth. I test the pure gold and 304 stainless because you asked me to use materials that don't oxidize. Even though stainless actually does oxidize, it still cold welds. Those familiar with heavy industry will recognize a common problem with seized stainless steel bolts. What is cold welding? Here's an explanation: https://youtu.be/Y2nQ8isf55s

Wringing Gauge blocks has always been one of my favorite and well-debated anecdotes. I find the forces at work just such neat concepts.
HAHAHAH bloody love this guy
Interesting. I work with 316, 308 and all kinds of other crap stainless and other steels. This is a new one for me. Maybe I need a refresher course. It's all ball bearings these days.
ya'll remember the days before the patrons and his tools looked just like ours. Now he has 30$ hammers and 15$ CNC machines helping him LOL LOL 😛
Is that a special gold magnet? I had no idea about that stainless seizing up
Also Newfoundland is beautiful! At least in a geographic sense. It's worth going to sight-see at least once imo.
I had two screws for a walmart dresser that were sitting together cold-weld overnight on me!
The two screw faces (where you place the screwdriver) are where they welded if anyone was interested.
Edit: on second thought it probably happened in the packaging… either way it was cool to discover.
Brother from another mother!
Wouldn't that be a friction weld?
The Gold-Gold may be not working because it's not very flat, in spite of it's sheen? Just a thought 🙂
I was making a 3” male to male X female thread X male thread cam lock adapter when I got the idea of loosely screwing the 2 aluminum parts together as I walked out of the supply store. Big fucking mistake! They wouldn’t come back apart by hand and as a last resort (to prove that they couldn’t get the best of me) I tried a 3’ pipe wrench and a vise. Bottom line is, yep… they got the best of me. Legend has it those two parts are still stuck together today.
“Right fucking dickered she is” the millwright I trained under 30 years ago said that almost everyday about something we would be working on. I haven’t heard that saying in years. Thanks for laugh and the memory.
My favorite life experience, telling a A&P yes aircraft mechanic about stainless galling up, He looked at me like I was the dumbest subhuman alive. Like I mentioned before he went to wrenching add some oil. Case and point. It ain't got any gas in in the tank…
I've been in commercial marine electronics for 12 years, use stainless bolts every day outdoors on boats and I've only experienced cold welding once. I installed an antenna (from a very large and reputable manufacturer) and used the stainless bolts that came with it (as I always do). Even though I've installed dozens of the same antenna every single bolt galled itself on this particular one, and on the next few I installed as well. Needless to say I started using never sneeze on those bolts, but a year later the problem disappeared and I stopped putting goop on them. I had just assumed they used shitty stainless. Whenever I use my own hardware I always use 316 stainless and I've never had them gall
You sound so young these days!
I use a product called Fluid Film on almost every bolt/nut. Convenient, prevents rust or galding, non toxic kinda expensive but a can goes a long way. Works remarkably well as a penatrating oil, If you have not used it trust me! It takes the place of So many different products and works better than most of them! See ProjectFarms vid on it.
Not sure how I missed it when this first came out. $0.02 from other sites. "The process also doesn’t happen instantaneously but requires pressure, time and vibration (force cycling)." All sorts of things you could do to improve the bond.
