braze with a torch and some flux.
oh, don't forget the harris wire.

1: ignite torch - do not ignite clothing
2: add flux
3: heat metal
4: add filler
5: do not grab peice with bare hands

no problem, what we are saying is that if you look around with the search button here you can see there are twelveteen hundred eighty five zero three posts on this. there is even a video on a sticky a few posts up from this one.


if you go to my post here you will see i have had my issues with brazing. it really helps to get the right stuff.

harris makes a kit you can find around on evilbuy and the rest of them guys sites... the stay silv flux and the wire for under 30 bucks. that will be plenty to learn with and build a rig or two.

get yourself a nice pencil tip torch. i had one of those nifty self igniting jobbers and pushed it aside for a 1960 something bernzomatic.

the rod from home depot will work with heat, ask natalie morgan.
i personally didn't have much luck with it.
then again i also went to the local welding supply and he gave me flux for welding aluminum and the wire is thicker than 1/16.


good luck and post up some pics.

Brazing 101

There you go, a full tutorial with pics I did a while back.

Took me a few years to get it right, its not something you pick up and master in an afternoon.

1st, what kind of solder are you using?
2nd, What material are you wishing to join?

There are many brazing materials out there. Some will not work on some materials. For instance, you can not use Silver to braze aluminum together.

The easiest way to learn is on copper. Buy a few pieces from the Home Depot and a "Benzomatic" torch and practice. Doing stainless and aluminum takes a lot of practice and patience and the correct solder.

I beg to differ. Brazing is incredibly easy to learn. If you know how to light a torch you can braze.

[bob1961]

i was bout to say that too....anyone remember my tigress build, well that is the first time i ever brazed small scale tube....i brazed solid steel bar stock making iron railings where i worked, but that was with a full sized torch set and brass brazin rod....doing little R/C tube work is almost the same but on a smaller scale, but i had to learn to use the smaller stuff the right way but it was easy..........bob

This is good stuff!
I just recently got a torch and stuff to get started brazing. I've got a lot of practicing to do but this really helps. I know a lot of it has to do with having the right materials such as silver solder and the flux to match. I don't have the matching solder and flux plus my solder doesn't have a lot of silver in it. I'm also using brass tubing and will soon pick up some brake line and solid rod. This should help me out as well.

I agree. The one thing I would add: you want the steel to be cherry red but far from "bright cherry" or orange to match the melting point of the 45% silver (1250F-1370F). Match your flux and braze correctly, and the flux will bubble when the steel is hot enough. At that point, remove the flame and "dip" (as shown in the tutorial) your rod to create the joint. Whatever you do, don't apply the torch directly to the brazing alloy, it will make your joints look bad and stick poorly. You want a fairly small rod, no larger than 1/16in. I've done a lot of work with 1/8in bare bronze, but rod that large is mostly suited to 1in and larger tube/pipe.

Yeah, ok. What do you use on Iron, how about getting copper and bronze to bond? Smarty, I said MASTER. It does take a few years to MASTER ever facet of brazing.

I wouldn't let someone cut into my drywall and braze my pipes if it was their 1st time. Would you?

[CrawlinClodKiller]

Good point when you get into dissimilar metals and thicknesses you have to have good equipment that has many degrees of adjustment as well as know the melting point of all metals you are working with. Actually will aluminum you have to watch the point where is just basicly vaporizes. It's pretty cool to see, but not what you want if you are working on it. My tutorial was when I was just learning basicly. That was from all the stuff I read online. No one taught me or showed me anything. Since then I have learned alot by reading and trial and error. The only things in my tutorial that I don't fully agree with now is some of my wording and the fishmouthing is not perfect in it which is pointed out.
