Flux core AL Wire?

admin

Never seen it. Does it exist? If not whynot?
Reply:Doesn't exist to my knowledge.  I suppose it MIGHT be possible, as there are SMAW electrodes for aluminum, but they are really a last resort and if you have the capability to feed wire, you're probably going to want to do it right.It's a good question, but even if it was possible, I doubt you'll ever see it.100% argon (or a mixture with helium) is the way to go.

Reply:I asked a guy from ESAB about this a couple of months ago, he said that as far as he knew none of the filler manufacturers have figured out how to successfully make it.He said that it's not a matter of the flux core itself, they've got the chemistry figured out, it's a matter of actually making the wire. See, with cored wires (both flux and metal-cored) they start out with just a flat strip of metal, then the roll-form it to a U-shape and dump the flux and such into the U and then roll-form it closed. At this point the whole thing is about 5/32" in diameter. With the wires for steel they just draw it down to the required size, but the aluminum doesn't have the tensile strength to hold together through the drawing process.Visit Tensaiteki.com
Reply:That makes a lot of sense.
