View Full Version : Experiment #1: Brazing steel to SS

I have been thinking of ways to connect tubes to the end plates of a 'sealed' cell.
What should we call a cell that is not dry and not sealed?
Anyways, using propane/oxygen and an ordinary bronze brazing rod and a little extra flux, I was able to braze a 1/4 -20 steel bolt to the side of a SS pot. (What else?)
It is a very strong bond.
Shown is without cleanup, etc.
I am worried about having anything else in the soup but SS however how slight.
Perhaps a lacquer coating or other dip would passivate worrisome materials?
Put this post in you FWIW department.

Ever tried an HHO torch? There are tutorials on youtube.

sp1ro,
Thanks.
I would appreciate it if you would share your expertise in brazing to SS using a HHO torch.
Why is it superior to propane/oxygen?
Thanks again in advance for sharing your expertise.

I never tried it, I just suggested it. Only expertise I have is in MIG welding. I just rec'd it because they say the HHO torch gets the hottest. You may be able to use SS alone. Last week I was watching some videos made by a guy called rain4fuel. He shows step by step how to make one and another video shows him using it melting granite and all sorts of other stuff.

I'm no expert in anything to do with welding, but I thought I would throw this into the conversation:
While I was experimenting with one of my close gap open bath designs, I lowered an ss bolt into the water to try and fish out a piece of splicing tape that had come loose. My electrolyzer was switched on and I, by mistake, touched the bolt across the side of a complete parallel set of plates, effectively shorting them out. There was a loud fizzling and the bolt stuck hard to the sides of the plates, I had to remove the plate set and forcefully pull the bolt off.
The reason I mention this is because there exists, if I remember correctly, a method of welding that is simply based upon a high current being passed through the two items to be welded.
Could this be of use here?
