I worked as a Jeweler / Goldsmith for over 30 years. I am just passing along a simple tip about soldering. The solder always follows the heat. To pull some of that aluminum solder down under the joint and a small amount to the other side. You need to heat that joint on the other side. You should see a small bead form on that other side when the solder starts to flow. I have also used these aluminum rods and I think they are fantastic. One last tip. Don't overheat your work. You used just enough heat till the solder flowed and that's good. Too much heat and you can actually cause the solder (call it brazing if you like) to boil causing a porous and weak joint. Thanks for posting!

In welding class we hit the aluminum t joints with a hammer to see if it will crack. It’s really crazy how tough 16 gauge is to tear or compromise. You hit the nail on the head with the preparation. Aluminum has got to be very clean if you want the strongest joint. A good weld/braze is like a good paint job 90% prep work 10% actually spent welding/brazing.

Hi, just picked up the neat holding method with the wrench. Those rods are usually an alloy of aluminum and zinc, they will stick to about everything metal there is. ( Copper, brass, steel, stainless...) One tip from a machinist/welder, not that it really matters in this demo, but prior to brushing, just clean with acetone so the grease don't get rubbed into the sheet, and, if the rods contain flux, no need to brush after you started, just keep the flame on the part, this will keep it from oxidation, the melting point of those products is around 850 F or less. (pure aluminum is 1200 F) Like you said it make a very decent bond. Appreciated the demo, Pierre

If you use a proper flux (and do your brazing off the huge heat sink of a concrete floor) you will get a better joint that will fillet on both sides, even if you only apply on one side. You will also be able to skip the majority of the wire brushing. Still; this does illustrate how strong a brazed joint can be, even when done less than optimally.

Concrete, like a fire brick, is a very poor conductor of heat. No flux is needed with these rods, but I am sure the result would be even better if you did use flux.

Few things here, great video and brazing aluminum is far easier than welding it and with aluminum welding isn't always that much better. Aluminum is fairly weak anyway, so brazing it normally all you need. A couple things that were not right it that while cleaning the area to be brazed, soldered or welded is always right, you are not removing oxidation. Well, you are but aluminum will oxidize as soon as you brush it. It is nearly instant. If flux is used it removes the oxidation when you heat it and the rod covers it so it never touches air. If you don't use flux you have to scrub though the molten filler to remove the oxidation and have the molten metal cover the base so it does not contact air. All that scrubbing was just taking a way a layer of oxide and allowing on other layer to form.

Don't know why all these videos are stating to use a STEEL BRUSH. I wouldn't recommend using any type of steel brush on Aluminium; especially, at this fragile molecular state. Preferable, use a new (dedicated) brass brush rather than any steel. Pushing Chromium (SS) into the Al will cause intergranular corrosion later down the road. Even sandpaper type must be chosen wisely before cleaning Al. I too would recommend using the proper flux with a nylon "toothbrush" for "longevity". But thanks for the other info, gave you thumbs up!

If you take a steel brush to stainless steel then the part you brushed will rust, actually it's the residue from the steel brush that rusts and not the stainless steel itself. Is that correct? When you brush the Al it leaves the same residue on the Al. I have told others to be careful what they use to clean the parts with that are about to be soldered/brazed and most people just don't care and use some kind of oily, greasy wire brush to clean with and then sit around scratching their heads wondering why their solder/braze joint failed miserably.

Excellent video! I did my first repair yesterday after having had these sticks on the shelf for over 20 years and it was great. I wish I had seen your video first, though, as I managed to partially melt the part I was soldering to on the first run ;-) I found it difficult to judge how hot to heat the aluminum, as the brazing rod didn't seem to wet the metal so well (I cleaned it as best I could, but the brazing was on the internal side of a cylindrical piece so the end result wasn't nearly as clean as yours) so my first attempt resulted in the aluminum part starting to change state, suddenly becoming bubbly. I didn't expect that! I have two questions: is there some kind of flux that can be used to clean off the aluminum in hard to reach places and to wet the surface, and can this brazing material also be used on copper instead of super expensive silver (service temperature expected, 300F)? Thanks in advance for your response!
@electronicsNmore
10 жыл бұрын
OK. For copper I use Harris Stay-Silve brazing rods. No flux required, just a super clean/shiny copper surface. As for the aluminum, no flux. It is imperative that the aluminum be SUPER clean. I would suggest using a dremel with a grinding stone to clean the aluminum before briushing it with a stainless brush. You overheated the aluminum. Heating MUST BE gradual. Once the rods starts to melt, pull the flame away and brush the brazing material into the surface , then re-apply the flame. Once the material starts melting again, then gradually back off on the heat or gradually pull the flame away from the aluminum. Once you get the knack, it is easy. Thanks for watching!

Just a side note, interesting video though I am still fascinated with this stuff. To be clear this is not a fusion welding process, the metal has not "fused" with the base metal. It has simply been adhered. This is the same adhesion process that brazing and soldering would be categorized under. The filler metal, in order to be a fusion process, must either be melted and coalesced to itself or have a filler metal of the same properties as the base metal become molten and as such fused together.

+TheMattynaught01 You can use what you want to clean the surfaces, but I only use a small stainless steel brush, and only recommend that my viewers do the same. You must be British based on the word "Learnt", and criticizing the word "aluminum". In the USA we say "aloominum".

@electronicsNmore

Hi there. NO flux unless you have the special flux designed for aluminum brazing. Just be sure to get everything really clean. Use sandpaper first, then use a CLEAN/NEW stainless wire brush. Remember to not apply too much heat, otherwise you may melt through the aluminum. Just do exactly what I did in the video. Thanks for watching! Be sure to share my channel with others, and rate a THUMBS UP.

Oh okay. I did get everything clean and its not working. The crack is showing up again thru the melted brazing rod. I figured out if I apply too much heat it will warp the aluminum. Whoops. Its not too bad though. Will do. Thanks for the reply.

Love2boat92 The brazing rod material does not have the tensile strength of aluminum sheet and will tear easier . When working on sealing cracks in a sheet, you need to bridge the crack with a narrow strip of aluminum and braze the strip to the sheet. .

psdaengr I would not underestimate the tensile strength of these brazing rods, which is around 40,000 psi. If you properly clean the aluminum being repaired, and drill out the ends of the cracks, you will have very low odds of failure. Adding a doubler is a good idea if needed. Thanks For Watching

electronicsNmore This was in response to the posters words "tore again" from which I inferred that he was trying to repair a crack in a sheet that tore under stress. Brazing isnt new. Aluminum brazing isnt new. Its good at making several kinds of joins. Butt and scarf joins aren't two of them, nor is resealing a crack. Sealing a crack through a sheet requires a lapping material because the crack cannot be cleaned; the brazing filler cannot penetrate or bond to the walls of the crack. Prebrazed sheet and strip is availble specifically for repairing cracked sheets. Once an aluminum member has failed under tension, the surrounding area becomes crystalized and weakened. If that section cannot be removed, it must be bridged to restore structural integrity. Aluminum and aluminum alloys are stronger than steel under compression, weaker under tension, and the tensile strength (resistance to stretching and tearing) is somehat proportional to melting temperature of the alloy.

if you use the Flux it will tell you when the alloy is at the right temperature to apply the rod, It is not necesary to steel brush while the alloy is hot as oxidation will only exist when alloys cools.

Thanks for this! The vid demonstrates the use of these alum/alloy rods for repairs etc. In the past I've tried bonding aluminum, with little or no success, without a mig welder. Aluminum forms a thin layer of oxide almost immediately on contact with air/oxygen so cleaning is huge. BTW - mig welding jets a flow of inert gas over the surface of an aluminum weld that displaces the oxygen from the surface so you can weld two pieces of Alum together. Thank you Joe*** for that tip. I already suspected heating technique played into the strength etc. of the joint. So the brazing/soldering material is drawn INTO the heat. As in soldering a copper "joint" by applying heat behind the actual joint to "suck" it into the connection. Peace. Great stuff on YT.

You want to use stainless steel. The bristles are harder than aluminum, and will scrape away the surface oxidation. Using an aluminum brush would be worthless. Both metals are the same hardness.

My understanding was that you laid a coating of rod on the individual parts, let them cool, then heat the two parts then press them together. But for my purpose this would probably work better. Is there a specific flux for aluminum? Also, can you use naval jelly to clean the parts? I'm going to repair a piece that's broken unevenly that won't lend itself to wire brushing.
