@HemiRod23 Год назад

I think this is TIG brazing. If you form a weld puddle on carbon steel and stick a silicon bronze rod into it, it will vaporize the silicon bronze because of the large difference in melting points. You can weld copper with a silicon bronze rod because they are similar metals with similar melting points, but copper or silicon bronze will not weld to carbon steel. When he talks about "washing up" with the filler metal, the steel is not melting. The proof would be to cut and etch the weld nugget to either verify or refute that it is a "weld".

As I have learned, in welding the two materials to be joined melt, with or without an added filler material. And in this video I don't see liquid steel, so it's not welding, but brazing. So I think your statement is correct.

@TheOneAndOnlySame Год назад

Beautiful welds Higher thermal conductivity doesn't mean that it "holds heat" (in fact it means exactly the opposite lol ) . It means that it conducts heat more. When you need to apply the arc longer to have it melt is because heat is actually spreading really fast in the piece and it can't quite concentrate at the arc's striking point as quickly as with, say, steel. Steel has poor heat conductivity, thus the heat you're inputting into the piece builds up really fast at the point of impact and has no time to spread fast enough : thus the metal melts right under the arc.

@@x91s55 in brazing the filler doesn't just lay on top. Rather, the filler heated to a liquid state is sucked into microscopic pores in the parent materials via capillary action (think of how a drop of water is sucked into the tight space between two slides for a microscope). Once the filler is cooled it is physically locked into both materials being joined, kind of like puzzle pieces.

As a transitioning flame welder on mainly brass alloys due to my previous trade (band instrument repair) I find this enticing and inspiring. Following you on IG and looking forward to one day gain the amazing control you have TIGing copper alloys. Also I've suffered from zinc poisoning and "not fun" doesn't even begins to cover it, just leaving this here so anybody not familiar with that gets a positive reinforcement on wearing a respirator or even better a fumes extraction system/device.

@scrapmanindustries 10 месяцев назад

I also got zinc poisoning once while gouging in a pit underneath a hydraulic press. Needless to say the second day in the pit I had a respirator on. And that wasn’t even good enough because I got carbon monoxide poisoning the 4th day. After that I got an air supplied hood. Way safer and tons more comfortable.

Here's a quote: "It is manufactured from alloy C23000 which is comprised of approximately 85% Copper (Cu) with no greater than 0.05% Lead (Pb) and 0.05% Iron (Fe) and the remainder Zinc" Also many copper pipe alloys contain small amounts of phosphorus and if he's getting headaches and other symptoms he may be experiencing phosphorus poisoning and thinking it's zinc...

I tried TIG brazing HVAC pipes and it just won't work unless it's a very large pipe. Too fine of a line between melting brazing material and the copper itself, and TIG arc can put out a LOT of heat. It's like trying to braze stuff with a lightsaber.

Looks more like tig brazing to me? Maybe diluting the braze material by melting some base metal in but don't know if i would call this welding. Do it with some ER70 filler.

@1dreadyzim Год назад

That filler would work fine if it weren't being meshed with copper, you can try it but I don't recommend it. Melting of base metal at all makes this a weld in fact it's the very difference between weld and braze.

@@1dreadyzim I do not know about this one in this case. It is a stretch to call that welding is what i am saying. Since the filler material ( that is commonly used for brazing) has a LOT lower meting temperature than steel had to say. So i would put it this way, If you Tig (or gas for that matter) brazed a joint and you over heated it and melted the base metal does it suddenly become a weld? I would say not. Its just an overhead braze and nothing was gained by melting the base metal. Or in this case there is really no need to even melt the steel. I would call this a braze joint. If the base metal melted it is just overheated and no need to do that.

All three types you refer to are types of tubing, not different alloys. My sources list copper tubing as available in C10100, aka 101, basically pure copper; and C12200, aka 122, with added phosphorus to deoxidize it.

@odinslockllc Год назад

I knew this can be done but the properties of both base metals wouldn’t make it a common method or a safe joint outside of “show & tell”. The old argument of braze vs weld can easily be proven by cutting and checking the weld nugget for dilution. It would be interesting to see what a CWI would say “on the record” with this. That silicon bronze is awesome stuff either way. Thanks for sharing!

@jackmclane1826 Год назад

It is a weld regarding the copper side and a braze regarding the steel side. A legit process and better than significantly melting the steel. You melt some steel - can hardly be suppressed completely with a manual process, especially if you need so much power to get the process running on the copper side - but that is more like an unwanted side effect. Tig brazing steel often also melts up some steel base material, the less the better. When it's not too much it works. When too much iron and copper are mixed, the result gets very brittle. Crackling on cooldown-brittle. Nickel filler can be used in that case, because Nickel works well with Copper and Iron in mixture.

I would bet money that this is occurring at or below 840⁰'s F, which makes it Brazing. Also, copper and steel won't combine chemically. What you have is slightly melted copper forming an amalgam with the filler, which is a mechanical joint!

@SolarMillUSA Год назад

That TIG arc is incredibly hot (18,000C at the tip). The traditional definition of brazing that uses temperature ranges kind of goes out the window when we are referring to a TIG process. We are left to consider the extent to which one or both of the base metals melt and contribute to the puddle. The fact that he is slightly melting in the edge of the steel makes this complicated, in fact I would say it is not ideal and should be attempted without the edge melting, because the contribution of iron into the weld pool will probably reduce strength. This is like 90% brazing.

Heat transfer equipment, heating and cooling coils for large climate control systems. The larg housing units on top of buildings are where you would most likely find them.

Very interesting. Was this just an experiment, or do you have uses for this process? In actual application of this process in a piping system, I would be concerned about catastrophic results due to galvanic corrosion. However, it is awesome that you were able to weld these dissimilar metals, just food for thought.

We do this in the manufacturing of finned tube heat exchanger coils and related heat transfer equipment and accessories, such as process gas coolers/heaters, transformer oil coolers, fan/coil units, face and bypass coils, frames for coil removal capabilities, airside transitions, and drain pans. These are used in a variety of industries including HVAC, fossil fuel power generation, nuclear power generation, industrial process, pulp and paper, automotive, and petrochemical.

The steel will be the electron donor and will oxidize. I would be most concerned about brittle weld as iron greatly reduces the ductility of copper.

@AJLorenz2202 Год назад

How would this be different if you were welding to a hole in the copper. ie: edge to edge.?

Thermal conductivity does not mean “it just holds heat”

The main thing I herd about Silicon Bronze is that anytime you use it your BRAZING and NOT WELDING

@raydreamer7566 Год назад

Great demo. I have TIG welded aircraft frames and motor mounts Aluminum motorcycle parts and so on BUT - please give me an application where copper is welded to steel ... I am thinking large electrical installations ?

@1dreadyzim Год назад

Heat transfer equipment, we make large scale air conditioning, heating coils some water based some oil and some steam. Different applications use different combinations.

@1dreadyzim I posted in a different comment about this. How do you address electrolysis in a water based system?

@1dreadyzim Год назад

@@nitrojunkie9027 I'm not sure about a lot of what goes on past making these pieces. I'd be interested in learning that myself to be honest

@nitrojunkie9027 Год назад

@1dreadyzim 10/4.....we're playing comment tag haha. Yeah, it would be fine without the introduction of water and last as long as the material. But with water it will deteriorate rapidly do to electrolysis. Thanks for the response man......peace

@1dreadyzim I am a Boilermaker and have seen copper to steel connections on old boilers hold up fine. But they were on sealed hydronic systems that rarely got serviced. Most new stuff and code requires some sort of dielectric. Aight man......peace

As I know welding is a process in which the base metal is melted. Soldering is when lower-temperature melting metal is used.

@elkvis Год назад

So you're both welding and brazing here. You're welding the copper, but brazing the steel. Interesting hybrid process.

I would think 5% dilution of steel into silicon bronze should be about the maximum. Any more would lead to a brittle weld. Copper is added to certain low carbon steel as it greatly reduces weathering corrosion. Corten steel is one such alloy.

Galvanic corrosion?

@esquiretheshieldbarrier2584 5 месяцев назад

What would be the purpose of having a steel pipe welded with a copper? I’m just curious .

@itsalldoable Год назад

Very interesting video, but I am confused as to why you would want to weld copper to steel. Copper inclusions in steel weld were always a massive NO NO when I worked in engineering. Surely the weld will not have any long term stability? Can you give me a real world example of there you may need to use this? I always use copper to help me to bridge a weld gap when welding steel in car body repairs which is my hobby. Kind regards Paul from 48SPOKES (UK)

You forgot about D W V copper pipe. Drainage, Waste, Vent . Sorry I’m a plumber. 😅 and I have a10’ stick of DWV that I want to make stuff with.

What filler wire please?

@scotthares Год назад

Oops, sorry, silicon bronze wire

@keithtynan7469 Год назад

If I had to, I’d guess that any two metals that form an alloy can be welded together. That assumption suggests that the weld would have the properties of the alloy, and not those of any parent metal.
