Awww man this is awesome! I am going to have the first topic! Hey BR!

Hi BR,

Did I see in a post of yours that you brazed some aluminum?

Does anyone know:

What tools are needed for working with small pieces of aluminum to weld them together without going to a TIG?

Thanks so much.

Yes, you did see a post of mine where I brazed aluminum to make the timer towers.
I used a Certanium 65 filler rod and a tig torch with pure argon.

Ummm kay.

Fascinating BR

Any photos of this set up?

I am looking to do really tiny stuff.

Not nearly as chunky as those towers.

Thanks

Not really much to show. If you Google "Miller Syncrowave 250" you can see the machine. I have the older style not the newer DX.

Man, if they're really tiny parts welding may not be the best option. Aluminum soaks up the heat quickly. It's possible that small parts would melt away before they would weld. With my limited experience I can tell you that aluminum goes from a solid state to a shiny puddle to a hole pretty quick. Can you bond them instead?

Yep.
I never had any success with welding aluminum.
It is not often I work with metals though so I was hoping for a miracle.
I guess it will be epoxy and/ or a cold connection.
Thanks BR.

Joe,

There is some product out there that is used in the auto body world that bonds metal to metal with no need to weld or rivet. Extremely effective product. Maybe some of the auto body people could chime in on this. I'm aware of the product but have never used the stuff.

Thanks Paul,

Maybe that will jog someone's memory.

I guess I was hoping for some way of soldering aluminum but I realize it is still a pipe dream.

Useful glues are always on my radar though.

Best,
Joe

There's always J-B Weld epoxy. but I've never used it on aluminum.

ive used jb weld to fill in a scrape/hole in a aluminum oil pan as well when i was doing demolitoin derbies i used jb weld to fix a aluminum transmission cooler........it worked for awhile lol then hot oil all over my back

Thanks DC

I will check that out.

I used JB Weld to attach a very small brass clevis on the solenoid trip rod of my start gate. I think the secret was to rough up the end of the rod with a file. mix up a small amount of the JB then roll the roughed end of the rod into the mixture. slide on the clevis and let set over night. The brass clevis holds tight to the steel rod, so far it's held very well. Lot easier than trying to weld something small. Try it I think you'll be happy with the results.

Thanks TT.
Good stuff
