Default Welding with pocket 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;

Umm good luck.

How do you plan to "weld" again?

What's your plan for shielding gas?

You can definately *braze*/solder with one though. Silver soldering renders a very strong joint.

Shit. I was going to weld a 3 ton rated towing hitch to my civic with that.

Alright since you all want to be sarcastic asses!

I'm talking light duty here, like something that would have probably 3-4 pounds on it, inside a house. Nothing going on a car, not even car related.

I don't know how to weld with it, thats why I'm asking. I guess you use one of those rods, and melt it on???? I don't know.

What material are you welding?

brass?
steel?
aluminum?

If you really ned something welded you'd be better off taking it to someone that knows what they are doing, so you don't hurt yourself, or anyone else.

Regardless, if it's only 4-5 lbs, solder it.

Acid core solder is extremely strong.

In addition to the acid core, you can even use flux for an easier joint.

Silver solder is even stronger.

I silver soldered the ends onto the clutch cable for my go-kart.

But solder doesn't really stick well to all surfaces. Your talking electrical solder right? Like for electrical circuits? Or some other kind of solder....they have thick stuff in the plumbing section of Home Depot I have seen before.

The application is plated steel I believe, its one of those 1"x1" square tubes that has 1/4" holes every 1" or so. I need to attach an aluminum 1.25" conduit to it.

You could use some quick arc welding, but it really depends on what it's made out of, and what it's being welded to.

Oxy-Acetylene welding doesn't use any shielding gas and I guarantee you that there are people out there who can gas weld with a torch every bit as nice as what someone can do with a MIG/TIG.

Westrock: It would cost you less money to pay someone to MIG the weld for you than it will cost you to buy that stupid little BRAZING torch.
Also - solder doesn't stick to metal when the metal is not hot enough. Electric irons don't generally have enough wattage to get metal much more than a 16th of an inch thick hot.

Go to Home Depot and get a $15 Propane torch. With that, you can solder and flux. More than you need. The Bernz-O-Matic ones.

The only way to bond steel to aluminum correctly without getting into some high-end welding technology is to braze/solder.

You can't ARC weld anything with a torch EVER. ARC is electric. Torches are gas.

My statement is true. Thanks for clearing it up a little bit better for those that don't know though. Click the image to open in full size.

Oh blah blah. The byproducts of the acetylene catalyzation and the high ratio of acetylene vs. oxygen in the mix form a "shielding gas" that prevents the metal from oxidizing.

How do you plan on working that out with a butane torch? If you actually could get the metal hot enough to melt it (assuming we are talking about steel here), the metal would "burn" rather than melt -- so you could not weld.

Of course, this is a moot point, considering mild steel melts above 2700 degrees fahrenheit.

I am talking about acid core solder. Rosin core solder (used for electronics) has no strength and will not bond to much of anything.

You can't weld steel to aluminum anyways. You will have to braze/solder it.

....And to braze anything you need a hell of a lot more heat than you're going to get out of your little butane torch thing there. We use oxy/acetylene rigs to braze copper lines to the steel outlet fittings on compressors when we do installs. I'm talking anything from small 3/8" lines to big 3" bastards. We use brass to braze and I'm just telling you that a butane torch like the one pictured is NOT going to be melting any brass rods any time soon.

Anyway, to the OP, go to a shop and have them work some magic for you. Trying to do it yourself when you have no idea what you're doing is just going to screw things up with you having to go to a shop anyway. So just skip the middleman (yourself). Click the image to open in full size.

you could make Creme Brulee with that torch. And then you can come on HT and tell us all how "fabulous" it was and how an accident with it gave you a permanent lisp.
