A quick video to demonstrate Silicon Bronze Brazing using Oxygen/Acetylene with an in line Gas Fluxer.
Work carried out building a Triumph T3 Racing MOTO 2 chassis
I have been trying todo a video like this for many years but really cannot stand the sound of my own voice :) its very painful for me!
To see this Motorcycle in action: • 2017 Dickies British S...
Race at Donnigton Park, Dickies British Super bike Race Moto 2 class - Pole position
Product Launch Video: • GP Sport R Launch Film...
Before you comment about your Tig/Mig welder, Please read...
Yes, it is a strong joint, In the UK allot of high end motorsport tubular chassis are built in this manner, very proven technique over the generations from Norton, Rickman motorcycles, Caterham Cars to modern day Ariel Atoms/Nomads and Racing Bike chassis, Superkart shifter chassis, Go karts ect.. And not to Mention Push bike manufacturers around the world.
This exact Motorcycle frame has been racing for 3 seasons now, Taking Pole positions and setting Lap records in its class (without any failures) Proving itself in the Runnings against all the big manufacturers Moto 2 machines. This motorcycle chassis has been Designed for bronze brazed joining from its initial stages as a racing motorcycle.
Many Thanks

When I left school one of my first jobs was bronze welding motorcycle frames, clip on's, rear sets and headlight brackets for a company called John Tickle racing equipment. I used to do it on piece work rates and earned good money. The job satisfaction at the end of each day was great. (Year was 1969)

I don't think I want to ride on that motorcycle. The braise all those joints it's can't be as strong as regular welding can it?

@@brt-jn7kg In general they are, the key here is having to deal with less distortion. You also don't get to worry about corrosion. You have to realize the materials are not molten here but the filler is. Either way a good weld or braze is often stronger than the base material. When it comes to precision fit it makes sense to braze. The type of filler is important depending on the application. The cool thing is you can braze dissimilar metals as long as they are "brazable" for example you could have a solid carbide part brazed onto that frame, you could have a stainless steel portion and not have to worry about contaminating it (where it would eventually rust if welded to common steel, specially without ss wire/rod). And probably a bunch of other pros and cons I can't recall right now!

Many, many years ago when I made bicycle frames at Dawes producing joints like this was the test to get the job but once you were on the production line they expected you to produce smooth joints which did not require finishing. The surface tension of the molten brass helps and holds the material in place. Also if you cut through such a joint you will see that there is a secondary smaller fillet on the inside of the tube creating a stronger joint.

"Also if you cut through such a joint you will see that there is a secondary smaller fillet on the inside of the tube creating a stronger joint." A fact that few are aware of. Well fitting and properly preped brazed joints are stronger, more resilient, and less prone to cracking than a TIG weld in general.
@lifuranph.d.9440 Ай бұрын
My company made race car, experimental aircraft and motorcycle frames out of mild steel [50k psi] to alloy steel [90k psi]. We used Eutectic Brand 1/16'' high silver content brass rod that made a tiny fillet...in and out. However, the joint fit had to be no more than 0.010'' to 0.015'' gap. We used a mill to make the cut to fit the tubes. The brazed joint was stronger than the steel in most cases. The special rod cost 5-6 times normal brass rod, but this was cheaper an stronger as you needed much less gas and rod with less cleanup grinding.
@gustavmeyrink_2.0 Ай бұрын
@@lifuranph.d.9440 Why would you make those things out of mild steel and braze them? If you're brazing anyway you might as well use better, stronger steel like Reynolds 531. There was zero grinding at Dawes, we used standard brass filler rods. The silver solder was only used for pump pegs, lugged 753 frames and such like but that had nearly no surface tension and you needed to be really careful and quick to avoid a horrible mess.

Yeah but.... there's always a but(t) - materials science & welding technology have moved so far on that brazing is really not required any more, and unfortunately is becoming a dying art. Selecting modern steels & TIG welding can yield much stronger, lighter and yes crack resistant structures. TIG welding properly also inputs less overall heat into the joint reducing the risk of distortion. Brazing still looks bloody lovely though!

The FAA in the USA forbids brazing aircraft frames. It is not approved due to the sudden and catastrophic failure of these joints. I examined a wreck many years ago that was brazed and saw evidence of brittle failure. The Pietenpol brothers petitioned the FAA for approval and after much testing, they were denied. Adhesion joints are not approved anywhere on the airplane. Look at your SN diagrams.

I used to work in a factory that makes fuel filler necks for the fuel tanks for school buses and I was a braze welder for that. Every piece had to be leak tested by pressurizing and submerging in water tank. No bubbles meant good weld. I welded on average 40 filler assemblies an hour. I had done mig and stick prior to working there but never bronze braze with a torch. Small learning curve to get the hang of it but well worth the experience. Now I use it occasionally in my home shop for hobby work. I must say though, my welds were definitely not on par with yours. Beautiful work!

Excellent quality bronze welding and demonstration. Is an oxidizing flame preferred with bronze welding or can a neutral flame be considered acceptable? I have a jet fluxer and will begin to practice on scraps to get the hang of the technique using Sifbronze 101 - which I have a small bundle of. I'm using 18 gauge mild steel pieces, no.2 tip and 3/32" rod. I use emery to clean the m.s. and then MEK to clean it up in preparation for bronze welding. I'm not expecting to get anywhere near the quality and appearance of your welds, but I'm doing it safely, and taking my time after taking a welding course at my local tech.. Any further advice is greatly appreciated. Have also viewed the gas flux bronze welding of Brian at Arch Motors working on an Ariel Atom frame. British motor racing companies preferred the use of bronze welding using a jet fluxer, and Lotus, Lola, Reynard and many more use(d) it for space frames as opposed to Mig/Tig due to less distortion. Thanks for a very interesting video. A+

@leonardpearlman4017 3 жыл бұрын
There are special lenses for this kind of thing, "Didymium glass", goggles, filter plates, clip-ons. Glassblowers use this also, it cuts out the yellow sodium flare so you can see. NO IDEA how this deals with all the green light from the flux! Gas Fluxer is a commercial product. It's a chunky little pressure-vessel filled with flux, your fuel gas bubbles through it and carries a little along to the flame. Super rugged but of course a little expensive. I once saw one in production, people were silver-soldering all day long, the green flame was really striking. They loved the Gas Flux action and were really positive about it. This was for constant daily use. I want one, but only braze and silver-solder occasionally, so a little regular flux is good enough. Here's a trick I got from an old BOOK: If you heat your brazing rod and put it in some flux (maybe lengthwise, in a little trough)... then gently heat this wire with your torch you can fuse that flux and make it run down the wire in a clear glassy form. So all that bubbling action is done, right? Now your brazing rod has a few inches of a clear flux coating on it, it doesn't make all that mess and confusion when it gets on the work! Just spreads out a little. This is for small delicate work. For something big you can just slather it on there with a brush!

Excellent content. Thanks for sharing. What type/shade lens do you use to view the puddle in the flame?
@sprocketandwheel 3 жыл бұрын
For brazing I use a shade 3-5..it helps if you are in a dimly lit room with no draft.. you want the joint to cool as slow as possible..

Nice job. What's the advantage of brazing like this opposed to TIG welding? I thought brazing with bronze was for dis-similar metals. Thanks.
@actualsurfer 3 жыл бұрын
One advantage is being able to get into very tight spaces. There are lots of arguments out there over the strength of this type of joining but one argument FOR it is that the HAZ is much less than for tig welding. This is a lower temperature. For heat treated Chromoly...there is nothing better.

@@Golgi-Gyges TIG Brazing is tricky because the arc is so intense that it's difficult not to bring the parent metal close to liquification, which diminishes the performance of the joint and cannot be detected after the joint is made (and sometimes is not even obvious to the person making the joint)

@@Gottenhimfella Wrong. Any good welder knows how to control the heat. And that is easier with TIG. All nonsense you wrote there. There is quite a melting point difference in the base metal and the bronze rod.

When you wrote that the health hazards are much less than with TIG did you mean due to the Thorium and Tungsten and the high-frequency electromagnetic fields and Ultraviolet and Infrared exposure with TIG compared to just some particulates and possibly a little phosphine or arsenic in the acetylene welding gas?
