What's on your bench?

[beaglebriar]

You would have SOOOO much better control and less mess if you used bare 1/16" and powdered flux. With powdered flux you can dip as needed instead of having that glass build up all over everything.

Thank you. I will try that as well. This brazing stuff is new to me. I've seen the HVAC guys braze at work and they don't even use flux. They tell me it's not necessary.

I'll have to try that. The glass can be tough to get off at times.

Before and after pics of a ms360 pro, decided it neededicated new plastics and air filter. It already has a new OEM P&C. I also have a new starter badge ordered. Let me know what you guys think

Looks great Dustin. Real nice.

See? We are learning stuff.

Ain't OPE a great site?

Flux is not necessary when brazing copper to copper, most likely what they are doing. Flux is required when brazing dissimilar metals to copper and for just about all other metals.

Flux isn't necessary. This is the stuff I use, turns out a great weld. Can be used with a tig torch also.

Wish i knew how to braze. Very handy to know and probably pretty easy to learn with right torch

Check the specs on that rod. Manufacturer's paperwork says-" bronze brazing flux is required".
May work without, but not as pure and strong.

Noone else has said it yet so I will, HOORAY page Tree Forty Six!

Guess that's where the tig comes in ( shielding gas).

I have tried a little tig brazing and got it to work but it wasn't pretty.

I use a jewelers torch with a small o2 bottle and regulator. I have a bigger setup, but this works real well for mufflers.

Mapp gas or propane?

 

[Isaac]

Some can get it to lay down like a stack of dimes. I have even seen motor cycle frames welded with it. I can lay down a nice bead on aluminum didn't quite get there with the bronze. I no longer have access to a tig machine . One day maybe.

A small tip helps a ton for controlling the heat when brazing.

Propane.

Very much so and when using oxygen and Acetylene you can get smaller tips to do more work faster, cleaner and more controlled than with propane or mapp. It is so worth the the few extra bucks to use acetylene and this is coming from someone that uses 10 to 15 thousand cubic feet a year.

The flux just gets it so it will adhere to the steel, just like soldering, it will be needed no matter which rod used coated or non, you can get by with less by dipping but it does take you off the work to dip, pluses and minuses both ways. Also when doing sheet metal work use a thin rod, the thicker rods take too much heat to melt and your base metal gets overheated, this is when you see a large spread of bronze.
I can't think of not one process that could not be employed with a small enough welding rod or wire. A 1/16" E6013 stick electrodes work quite well on sheet metal, .022" hard wire and Co2 shielding gas is a good set up. Even .030" flux cored turned down could be used in a pinch. Oxy/Acetylene weld with a small tip and rod and brazing. A tig set up is the king but most costly to set up.
What I'm trying to say here is go ahead and use whatever you may have at hand, practice on some scraps first to get the knack and mod away.

I have some junk mufflers to play around with. I'll break out the torches this week and see what kind of mess I can make.

Luvin on some 288. These things are just so easy to work with.

will it hold a 12 foot john boat ?
