Braze Welding Demonstration

- In this video I discuss braze welding.
I am joining carbon steel with bronze filler metal using a powder flux.
This video is part of a course in the Advanced Manufacturing Technology program at Hudson Valley Community College in Troy New York.

I always wondered what the difference was between that and welding. Great video thanks for sharing.
helpful demo, thank you. I only have propane/air available in the school workshop so will have to see if I can get the right temperature for a basic braze joint.
Really nice explanation and demonstration. Personal note, I think your video would have been better without the music only because I found it mildly distracting and couldn’t focus 100% on you. But your teaching style is really fluid and very understandable. I’ve bought a mig welder but with zero experience welding I’m too cautious to use it, so I might get a brazing torch instead.
4:31 the brazing actually starts.
Very nice demonstration. Thank you
Glad it was helpful! Thanks!
Well, I'm going sound contradictory, and maybe that will start a discussion...
This demonstration is just "brazing", where bronze filler metal "sweats" into a joint.
I'm trying to learn real "braze welding" where a steel joint is joined by an actual fillet bead. This appears a defined stack of bronze dimes.
Every single person I talk to says, "That isn't possible."
I know it is possible. I first saw the process on Irish race cars, and the science behind that particular method of joining steel tubing probably saved my life more than once.
The closest if come to seeing real "braze welding" are the bicycle frame builders, but too many of them are simple sweating joints together.
you're right, this is brazing, not braze welding, and they are definitely two different things. My understanding that brazing was used for industrial applications, black iron pipe, industrial plumbing, cast iron repairs, etc and braze welding was used where some measure of flexibility was required, where actual steel welding would be too brittel. I've onle ever seen it used on race car and motorcycles chassis where a degree of flexibility is desirable. I think with the advent of TIG it has become almost a lost art form, with only the old school chassis tuners really usgin it anymore.
did you find anything
natural gas pipeline welder here , in my career this was done in the 1940's the brass bead was beautiful a perfect stack of dime , on brazing steel to steel or copper to steel , looked like a machine weld , nice uniformed bead, i practiced and got to where i could run a bead, it appears in this video he is using a 2-tip , i could not see the adjustment , just my take i would use a 4-tip with a large feather adjustment , good luck on your quest to gain a lost art
Bit late to the party, but...
There is a fabricator with a you tube channel called Paul Brodie - he build bicycle frames (and does a whole lot of other stuff too) and has some good videos on various types of brazing including fillet brazing which might be what you're looking for.
Nice explanation and example. Thank you
Glad it was helpful! Thanks!
You can read about this in old books about welding. How old? Say, they have black and white illustrations, and refer to the person holding the torch as "Weldor". Or "man"! They call it "Bronze Welding" which has caused a generation of confusion. My understanding is that this refers to something you do with a torch and filler (like low-fuming bronze rod) that LOOKS like welding! Local heat, fillet. "Brazing" has been done for centuries, before there WERE torches, and generally involves broad or overall heating and filler metal flowing where it will. This might refer (I just this moment realized) to something small like a little ring, the jump ring jewelers talk about! SO: when you silver-solder a RING closed, it's BRAZING!!! You heat the whole joint, the silver brazing material flows all at once by capillary action, the heat is not local. Brazing a carbide tip on to something, brazing tubing in to a socket might all be the same. Are you with me? I think for Bronze Welding you want intense concentrated local heat typical of welding, but not enough to melt the base metal. I've never quite managed this but will one day! I have done it with TIG heating and silicon bronze which doesn't quite seem sporting. If I watch enough videos and buy enough torches surely it will happen by itself?
This is neat!
10th MTN!!!! CLIMB TO GLORY! DEEDS NOT WORDS!
Thanks!👍👍
Don't have access to an actual welder. Heard about brazing two pieces of steel. Nice. This works for most of the things I do.
Thanks! Oxyacetylene welding and brazing is an underrated process in my opinion.
Are you able to use just a propane torch like the ones you can pick up from harbor freight/Home Depot this is something always wanted to learn
Mapp has will work with skinny metal
No Country for Old Men brought me here
Dude same! Lol
Tanks man
You’re welcome!
When I was at college we were taught that the oxy/acetylene mix should be slightly carborising i.e. slightly more acetylene than oxygen for brazing.
Not sure where this guy learned to braze. I've seen brazing on English race car chassis with perfect stack of dimes brazing welds on hundreds of tubular joints. Not the rather sloppy brazing displayed here. You can also see beautiful stack of dimes brazing on custom bike builders sites where they build bikes of the classic steel frame style.
Didn't get to see the flame adjusted. Couldn't see the brazing process,
The guitar background was monotonous and unnecessary.

why he has so much trouble swallowing
why so rude !
OK 10th. The term "welding" does not in any way apply to brazing.
Brazing is not welding , you must be university educated . Sorry for your loss LOL
Hi.
I need to do a crash repair on a Miata...in UK.
Only panels..thin metal and not structural.
I'd rather braze...to keep the temperature down...so as not to blow holes.
Can you recommend the brass/bronze rods...flux and a cheap way with what gas... without having to buy a huge set up with oxy bottles.
??
Thanks🙏🏼
What’s the gauges on the tank set at
Probably 5 PSI for acetylene and maybe 30 for oxygen. I taught high school agriculture, and I never let my students get acetylene above 5. @vondinkinsvon8919
