That's very nicely done! If anyone cares, I'm pretty sure this is BRAZING. I mention this b/c I teach basic welding in a small way, and one of the curses of my existence is that people (especially on eBay kind of situations) will call ANY DAMNED THING "welding" if there is any fire or sparks involved. This doesn't take anything away from the JOB, it just makes teaching and shopping difficult and confusing, and really screws up the beginner! This process might not have a good name! But it's a strong analogy to BRONZE WELDING that people do on steel. That is also a rich source of confusion! I think a problem everyone has is not realizing the whole temperature span of soldering/brazing/welding has moved WAY DOWN with aluminum! Beginners TRY to keep in mind: In WELDING the base metal melts, the original edges are lost. Anything else is not welding! Soldering, brazing, sealing wax, I don't know... so many options! As an analogy, you can WELD brass, and BRAZE brass, using the same rod and the same torch! You don't use it in quite the same way. I do this demo to clear up confusion among the students.
It all depends on whether "The "Aluminator" rod has been fused and has melted with the base metal. Is the filler rod the same alloy as the aluminium tube? It is advertised as an alloy, but we don't know if it is different from the aluminium tube Bob is working with. If they are the same composition (or have the same melting point) and they are FUSED together, this is WELDING, if the rod contains different amounts of the alloy element (magnesium, silicon manganese, copper etc) and the melting point is (normally) lower, then we are looking at BRAZING if the base metal DOES NOT melt and fuse with the base metal. Pure aluminium is very ductile and not commonly used in any castings where strength is required. Mainly used in power lines. So all the aluminium alloys we will be working with are an alloy of some sort. Silicon brings down the melting temperature of the aluminium which makes it an excellent alloy rod for brazing, but if the base metal is also silicon aluminium alloy or has a similar melting temperature, then this is welding. Bob has melted the rod onto the base piece, but it did not melt the base metal.. Brazing and welding are not exclusive but can overlap. Unlike steel, if you apply a little too much heat to aluminium alloy base metal, your weld will be on the floor. If Bob had left the flame sit too long in one spot, the brazing would have turned to welding and if the flame wasn't moved away, to a fused blob on the floor. Now think of soldering a solder made plate. This is technically welding. Yes you can weld solder but because it has such a low melting temperature, "they" call it soldering. When you solder copper, what is it? It is brazing. If you are good enough to melt the base metal as you are adding the filling rod, you are welding even if the two metals are slightly different. There are many GREY areas in welding brazing and soldering, which is why it's better not to overthink them.
@@moto_rad Had another close look at the video. No he did not melt the base metal. He brought it up to the melting temperature of the filler rod. The rod packet clearly states flux coated aluminium JOINING alloy. These filler rod have silicon and a much lower melting temperature than aluminum. So this is commonly called brazing. Aluminum has to be well heated before brazing and welding. With the latter, a fine pointed flame is used and you focus the heat to one point where the puddle will appear and will be translucent. If you melt some alloy into rgis puddle, it is welding. It is tricky to use these rods for welding because the base metal has a higher melting point. More than the melting temperature of the rod. To weld you have to keep the filling rod more distant from the base metal and bring it in as the translucent puddle appears. Very easy to have the base metal collapse as you juggle flame and low melting point filler. Much easier to weld with a high melting temperature filler rod. In this video, the pipe is heated but not melted. With such a feathered broad flame, if the melting temperature of the base metal was reached, it would probably end up on the bench.
Well I have to hand it to you Bob that’s a damn good job you’ve done there… I was skeptical in the beginning but as far as I’m concerned you’ve come through with flying colors,,,my hats off to you sir..👍
Thank you!! I’ve been looking into the mini oxy-propane torches for a number of reasons, but welding non-ferrous metals is a must. You’ve shown here that not only is it possible, with practice it produces excellent results.
Mr Steven's, I have the same idea. I bought a clone Smith mini torch. Using flashback arrestors on the torch lines. My idea was to use it for making aluminum projects. Such as; I use an aluminum ramp to load euthanized pigs into my 4x4. The ramp is 100 percent riveted together. I plan on using the aluminum welding rods to make the ramp stronger and more durable. I need to practice before I take on this project. Do you have any set up suggestions.
Very cool video. I tig aluminum a lot and figured I could give torch welding a shot. I have a ton of brazing/soldering experience, and at first glance this seems like brazing to me. However the filler material definitely is not a brazing rod. Aluminums low melting point makes me wonder if the filler is actually functioning as a weld (both filler and work piece melt) and actually flowing through capillary action like solder/brazing. Regardless of the technicality of what is going on it would be damn near impossible to get much of a stronger joint on thin aluminum tube than this. Tig welding on such a small diameter and thin tube would be more time consuming, much more difficult, and likely not produce a stronger joint. Anyway cool stuff, thanks for sharing 👍🏻.
A very straightforward explanation and demonstration, thanks. My only criticisms are that the flame tip wasn't in the camera frame when you were describing it and the cut marks on the tube were out of focus, other than that very informative. Thanks.
I looked up this product, and the maker describes it as follows: ”GENERAL CHARACTERISTICS: Universal electrode for arc welding or brazing all weldable grades of aluminum and its alloys. Good arc stability at low amps and minimal spatter make The Aluminator ideal for any maintenance or production application.” To me this looks like brazing since u melt the rod with the flame, not with the pool of molten metal. But maybe I missed something. Looks very useful though!
hmm I am trying to weld some aluminum lines but needs to get the hang on it but must say you have that technique clean I guess that when your a professional great video
This is brazing not welding. You can tell by the lack of a weld puddle and how the filler rod flows. Also, you can see that the entire part is geared until the filler melts against it and then it flows along the joint. I weld aluminum with acetylene and its very different. Aluminum should not be welded with propane. The heat is insufficient for a good weld. Hydrogen or acetylene works. You create a weld puddle and then dab the rod in like rig welding. Its very similar and the result looks the same. Unlike here where he backs off the torch until the surfaces are hot enough to melt the filler, when welding it you have to put the tip of the cone on the joint until the surface starts to wrinkle and then dab or scrape the rod in the weld pool. Once you start it you travel along the weld jut like rig welding. Guarantee 100%, that is a brazed joint. I'm not throwing shade on it though. Its a very nicely brazed joint.
Actually, I used acetylene for 20 years before switching to propane. The reason I did so is I had a hard time getting clean gas that would not contaminate my welds. It was weird, one day all was good, put on new bottles and welds turned black. Tried multiple new bottles. Installed an old bottle I had and everything was fine. I switched to propane as it is a cleaner gas, It works for the very small items I weld. If the aluminum was thicker it would not be hot enough. Yes there is a puddle. I tig and gas weld and braze. I feel that I can tell the difference between the two.The filler rod I use is not a low temp brazing rod you find on the net. It is an aluminum welding rod. You can cut the finished welds and on inspection, you cannot tell what is base metal and what is filler. All that said, call it what you want, I am simply demonstrating safely, permanently joining aluminum parts. Right or wrong I have used this product daily for 30 years with no failures.
It looks to me like the filler material has a very low melting point around 800° to a 1000° which would classify this process as soldering, brazing with the brass and bronze alloys takes a much higher temperatures around 1800° and up and usually brazing is done with dissimilar metals
100% correct Michael, it’s amazing how many RUclips videos get this wrong. What gets me is that this guy looks like he should know the difference by now.
That was the conventionnal way of welding alu before TIG (heliarc invented 1942) and MIG invented far later. All the alu during WWII was welded by torch and fluoride flux.
Thanks for the video. One suggestion. When you're trying to get a close up shot put your hand behind the object you're trying to focus on and the camera will focus much better.
Excellent video, lots of real time experience. What kind of pressures do you run on the gauges? Thanks for every informative video, would like to see more. You take care and good luck.
This is brazing or soldering as the filler rod alloy has a lower melting point than the base metal which you do not melt. But I really like it and I will use it !
Question for you Bob. (a great video BTW I got a lot out of this) I have a lot of aluminium miter joins to braze. The material I need to join is 40mm x 3mm flat-bar, corner joints (mitred 45°). Would this pas option be able to braze this connection? Regards.
Thanks thats what ive been wanting to do. Great information. Can you lay multiple beads one upon another to fill a hole by letting it cool a little and comming back a few times to fill or could you just add a plug and weld it in? Thanks i really love brazing but never seen it done like that great video
You can do both. I lay the rod perpendicular to the tube. Melt the rod slightly and forming multiple logs across the tube. Then you can carefully heat the material and slightly flow it. It takes practice as the melting point of the rod is just slightly less than the base metal.
Thank you, kind sir!! very helpful! I was wondering what torch tip you are using. and p.s.. I don't care what they say the process is called lol ! I personally just care that it works. I believe it is getting hot enough to actually be a weld!
This is actually brazing and the internet doesn't recommend welding with propane due to creating weak and brittle welds . Do you think if you were to actually use propane to weld ( involves making a molten pool on the base metal ) with these rods , SMAW rods , or flux it would create a descent weld since they have flux incorporated onto the rods ?
Yeah, I was just asking myself if this was actually welding or brazing. Your comment might be a bit harsh Airon, but this seemed to me to be brazing using capillary action.
Hate to split hairs but is this really welding or brazing? You're not melting the base metal as far as I can tell so I'd tend to call this brazing. Regardless, the end result looks good and I'm certain it would perform well. Thanks for the video
I wish I could get those rods locally. No one seems to carry anything Messer here, and I've struck out entirely finding somewhere to order them in. Nine months later... eBay to the rescue. I'll have to give this a go some time soon!
Do you use a particular propane torch head? I watched another video where the gentleman said to use a #1 propane torch head. Great video by the way. I am building an aluminum frame for a hookah diving compressor and I'm new to welding aluminum and using propane/oxy combination. I couldn't find the exact rod brand you mention, but I found one exactly like it sold through the Blue Devil brand on Amazon. I'm just waiting on getting my order of Aluminum Oxide sandpaper to start.
technically clickbait since this is not welding. it's soldering, or possibly brazing, depending on the melting temp of the rod. welding melts the base metal.
Can this process be used for welding truss-style structural frames of 1/8" wall tubing (for my truck camper)? I have a torch and a flux core wire machine...trying to decide if I should use the torch, upgrade the flux to gas/MIG or pay someone to TIG it
You will not be able to get enough heat buildup with a torch. This rod is for stick welding so you could use a traditional welder. I think tig or mig would be best.
For the most part, no. You cannot get the metal hot enough. There are aluminum brazing rods on the market that work well with Map gas. This rod requires the metal be up to its melting point to add the filler.
According to Messerweld, this is good for 1XXX, 3XXX. 5XXX. and 6XXX series. There's a data sheet online, it doesn't say much. MG welding products, or "Messerweld". They don't say what the alloy IS, which is a little odd and typical of welding products sold for "maintenance". This leads one to suspect that it's something common given a cute name and a higher price! The few Messer products I have tried worked very well by the way. I suspect that in this case what we have is an aluminum brazing alloy, something like Aluminum 12% Silicon, which you can buy. What we see here sure LOOKS like brazing, there's general heating and capillary flow, the base metal is NOT MELTING! I think it in every way fits the definition of brazing! I have done similar stuff using brazing wire and flux. The molten metal is very fluid and pulls through a joint easily. The action is not at all like welding!!!! You have to get that flux OFF of the material as soon as you can, from what I read. Other than that, it's a really cosmetic job.
@@leonardpearlman4017 thanks for responding. I also have used this type of rod on thin 22ga. aluminum quite successfully. Alumaloy and the stuff harbor freight sells. Everything clean and sanded and propane torch, good fitup with the idea of using capillary action. A sweeping motion with the flame and swiping motion of the filler metal along the joint works well. It helps to "tin" parts that have an awkward fitup. The thin base metal would become annealed yet the filler metal would be harder. It acts very much like soldering but a little fussy if things aren't absolutely sterile clean.
Propane is cleaner, it does not contaminate the weld like acetylene. Acetylene will work but it is often contaminated and produces very dirty/poor welds.
So, I’m not a big safety guy, I’m not a safe person, but trust me, put some gloves on, I had a 2nd-3rd degree burn on my wrist from an oxy torch and the recovery was horrible, so please, put some gloves on
Well you should probably be more careful 😅 Said the person who almost cut their own finger off a week ago because they don't have a safety guard on their grinder 😂
@@bobsteinmann5793 It certainly is not. The base material is not being melted, the rod is melting and being drawn into the joint by capillary action, i.e. a brazed joint.
the definition of brazing also has a melting temp. above 900 or 1000 degrees, welding is technically fusing base material with the same type of filler material
@@mr2981 Thank you, voice of reason! It's possible in some cases to WELD or BRAZE at will with all the same stuff! I have done this as a demonstration with brass and the popular LFB filler material. You can braze or weld two pieces of brass together with the same torch and the same rod, just depending on what you DO with the torch! I think M R is completely correct here. A brazed joint might be JUST what you want here, by the way! Very strong and neat. That darned flux is the only drawback.
That is not welding. You are brazing. The difference is that you are not melting the base metal. Welding requires melting the base metal. I use this brazing process because it is easy but it is not near as strong as a TIG weld.
That's not welding .that is brazing or hard soldering ..your not melting the base material as in a proper fusion weld .you have not created a welding puddle you melting a filler only
I recommend trying it. Yes the filler rod melts at a slightly lower temp than the base. Most of the time the base metal is melting at the same time as you apply the rod. Correct there is no puddle, but you dont have that level of control with gas welding. I weld tig and gas and this too is a weld. It can be argued several ways, I say, try it and then let me know what you think.
Actually, That is exactly what I am doing here. This is not a low temp filler rod like so many you see on the market. The rod is aluminum alloy welding rod covered in flux to shield from oxidation.
In another situation, if this was used for example AS an electrode in arc welding (!) the arc would probably melt the base metal, and our rod would flow on to that and it would BE "Welding"!!! Here it's heated up and flows about and flows deep in to the joint like water I'm telling you, in a way more typical of soldering and brazing don't you think so? A nice strong cosmetic job I think we can all agree. The same thing might be done with standard aluminum brazing alloy (aluminum and 12 per cent silicon is common) and a little jar of aluminum brazing flux. What we see here is very nicely done, I don't mind repeating.
That's very nicely done! If anyone cares, I'm pretty sure this is BRAZING. I mention this b/c I teach basic welding in a small way, and one of the curses of my existence is that people (especially on eBay kind of situations) will call ANY DAMNED THING "welding" if there is any fire or sparks involved. This doesn't take anything away from the JOB, it just makes teaching and shopping difficult and confusing, and really screws up the beginner! This process might not have a good name!

It is brazing although not as strong as welding a brazing weld is still considerably strong if done right .

What is the name of that rod for welding alminium
Have you had any success using straight Map or propane gas with no Oxygen? Just wondering.
For the most part, no. You cannot get the metal hot enough. There are aluminum brazing rods on the market that work well with Map gas. This rod requires the metal be up to its melting point to add the filler.
Please let us know where it's available.
That seems more like brazing than welding.
Isn't this brazing?

According to Messerweld, this is good for 1XXX, 3XXX. 5XXX. and 6XXX series. There's a data sheet online, it doesn't say much. MG welding products, or "Messerweld". They don't say what the alloy IS, which is a little odd and typical of welding products sold for "maintenance". This leads one to suspect that it's something common given a cute name and a higher price! The few Messer products I have tried worked very well by the way. I suspect that in this case what we have is an aluminum brazing alloy, something like Aluminum 12% Silicon, which you can buy. What we see here sure LOOKS like brazing, there's general heating and capillary flow, the base metal is NOT MELTING! I think it in every way fits the definition of brazing! I have done similar stuff using brazing wire and flux. The molten metal is very fluid and pulls through a joint easily. The action is not at all like welding!!!! You have to get that flux OFF of the material as soon as you can, from what I read. Other than that, it's a really cosmetic job.
@@leonardpearlman4017 thanks for responding. I also have used this type of rod on thin 22ga. aluminum quite successfully. Alumaloy and the stuff harbor freight sells. Everything clean and sanded and propane torch, good fitup with the idea of using capillary action. A sweeping motion with the flame and swiping motion of the filler metal along the joint works well. It helps to "tin" parts that have an awkward fitup. The thin base metal would become annealed yet the filler metal would be harder. It acts very much like soldering but a little fussy if things aren't absolutely sterile clean.
So propane and oxygen is more efficient for aluminum because its cooler than acetylene?
Propane is cleaner, it does not contaminate the weld like acetylene. Acetylene will work but it is often contaminated and produces very dirty/poor welds.
So, I’m not a big safety guy, I’m not a safe person, but trust me, put some gloves on, I had a 2nd-3rd degree burn on my wrist from an oxy torch and the recovery was horrible, so please, put some gloves on
Well you should probably be more careful 😅
Said the person who almost cut their own finger off a week ago because they don't have a safety guard on their grinder 😂
wouldnt this actually be brazing? or is it weld because the filler is also aluminum? please clarify Im a noob to
It is a weld. The filler is Aluminum. Imagine tig welding, except the torch is a flame instead to electric arc. The Flux is like your shielding gas.
Bob Steinmann thx ☺️
@@bobsteinmann5793 It certainly is not. The base material is not being melted, the rod is melting and being drawn into the joint by capillary action, i.e. a brazed joint.
the definition of brazing also has a melting temp. above 900 or 1000 degrees, welding is technically fusing base material with the same type of filler material
@@mr2981 Thank you, voice of reason! It's possible in some cases to WELD or BRAZE at will with all the same stuff! I have done this as a demonstration with brass and the popular LFB filler material. You can braze or weld two pieces of brass together with the same torch and the same rod, just depending on what you DO with the torch! I think M R is completely correct here. A brazed joint might be JUST what you want here, by the way! Very strong and neat. That darned flux is the only drawback.
Hi I want to weld aluminum kattle spout
Where I can purchase this rod?
most welding supply stores. I use Matheson.
This is called brazing...
That is not welding. You are brazing. The difference is that you are not melting the base metal. Welding requires melting the base metal. I use this brazing process because it is easy but it is not near as strong as a TIG weld.
that's brazing, not welding
I see the Aluminater rod has a flux coating where most aluminum welding rods do not. Will this increase strength?
nothing to do with strength. no metal was welded in this video.

Tutto prossimamente ok
That's not welding .that is brazing or hard soldering ..your not melting the base material as in a proper fusion weld .you have not created a welding puddle you melting a filler only
I recommend trying it. Yes the filler rod melts at a slightly lower temp than the base. Most of the time the base metal is melting at the same time as you apply the rod. Correct there is no puddle, but you dont have that level of control with gas welding. I weld tig and gas and this too is a weld. It can be argued several ways, I say, try it and then let me know what you think.
Sorry !!! But this definitely is NOT !!
welding.... Welding is bringing two metals to their molten point for fusion. This is brazing not welding.
Actually, That is exactly what I am doing here. This is not a low temp filler rod like so many you see on the market. The rod is aluminum alloy welding rod covered in flux to shield from oxidation.
@@bobsteinmann5793 hmm. I'll have to give it a try. If u don't mined me asking what psi did u. Use for propane.? & oxygen ?
@@bobsteinmann5793 what was psi of propane and oxy
@@keithyz3943 25 psi oxy 17 propane
In another situation, if this was used for example AS an electrode in arc welding (!) the arc would probably melt the base metal, and our rod would flow on to that and it would BE "Welding"!!! Here it's heated up and flows about and flows deep in to the joint like water I'm telling you, in a way more typical of soldering and brazing don't you think so? A nice strong cosmetic job I think we can all agree. The same thing might be done with standard aluminum brazing alloy (aluminum and 12 per cent silicon is common) and a little jar of aluminum brazing flux. What we see here is very nicely done, I don't mind repeating.
This looks like brazing not welding.
This is not welding
Yes it is. This isnt a silver rod. He is melting aluminum together, and adding aluminum filler. Exact same thing as TIG.
