Question Possible to weld metal with small butane torches????

Hey guys, I was wondering if you can do light use welding of like steel and aluminum with these hand held butane torches. They say they can get up to and over 2000*F

Like these little things;

Most likely not. Temperature isn't everything, you also need to consider the energy the torch is able to put out. If it doesn't put out enough energy, the material you're welding will dissipate so much heat that the torch is unable to heat it enough. Look for something a little heavier

Ya. It can't even weld your fingers, and skin is really weak stuff when it comes to comparisons with metal. Seriously, those POC's have less heat than a candle.

Note that with a burner like THIS, it only gets maybe orange hot (1600-1700F) in free air, despite the prodigious amount of power output. Putting up some firebricks to hold the heat in can bring that to melt steel but the heat is too diffuse to actually weld a joint or anything.

So. For one you need a temperature higher than the melting point of around 3,000°F. Acetylene and pure oxygen burns upwards of 5,000 degrees, it's very hot stuff. Plasma in the form of a high-current arc has even more, the low end being around 10,000°F. Put 100 amps at about 20V into a space that small and you'll melt anything.

Heh. This post looks more like describing how to build something, without giving anywhere near enough details to do so, than just telling you why it won't work. S'pose I *am* tired yet...

To join aluminium you can use a torch like that for fusion welding. Technoweld have some little kits for that purpose, that comes with a good beginners manual.

Ive been building bicycle frames like that once, just to see what happened....and it worked rather well.

actually I have found welding with a standard torch on aluminium difficult...hold it too long and it'll burn through the metal...duhz...

Oh, I was going to add, oxy-acetylene (O/A) can weld steel but oxypropane won't work. I don't know why, I'm not a weldor. Works fine for cutting though. AFAIK, anything with enough concentrated power (arc, O/A, O/P I guess... possibly oxybutane to keep it on topic ) can do aluminum. As I recall, you need special fluxes for gas but arc is done on AC and that has a fluxing effect. Not to mention being under an inert gas.

Oxy acetylene is too hot for aluminum. You need oxy hydrogen. Or better yet mig. Hobart sells a small mig setup for $650.00. you can also use it for steel up to 3/16" in single pass.

Stick with screws and rivits for aluminum unless you want to spend big bucks and lots of time learning.
