fluxcore for fab work

[oregonaaron]

We do a lot of farm type welding work and have been hearing alot about guys running fluxcore wires. Besides wind issues, what are some advantages of running fcaw with shielding in new fab projects. Better penetration? Stronger welds?

you can get fluxcore wire that has the same tenslie strenght as a 7018 rod. plus its easier to weld out of position then stick welding,so you get the best of both worlds the ease of mig and the strenght of stick welding....shop around and find GOOD wire....im still searching for it mytself

Fluxcore is also more forgiving when welding on rusty metal.

is there anything but flux core? that's all i ever run, when you want to get it done fast, it's the only choice- burns through rust, paint, really cuts done on prep work. problem is it's not very good for you- lots of ventilation boys.and girls

The desposition (sp?) rate does seem a lot higher. What wire do you like using?

[dob]

t-91 LF is what I use. LF stands for low fuming; I might live a day longer that way

i use .35 e71t-gs , it has a better fusing ability over nr-211 in my opinion, i am using a roll i picked up from walmart in a pinch, it has been very smooth though, i usaully order several rolls at a time from weldingdepot.com

Arcdawg, you can buy solid MIG wire with the same 70,000 psi tensile strength of 7018. You can buy TIG filler metal that has that high and higher tensile strength as well. Just figured I'd inform you. Fluxcore does seem to cut down on prep work, it's closer to stick in that it's a little less picky about what it's being used for. It's a little faster than MIG as far as desposition rates too. It spatters and fumes similarly to stick, so take that into acount as well. Good luck on your weldin'!

yeah custom thats why i wrote this, thanks for the info

Oh okay, I thought you meant that only FCAW can have high tensile strenghts, and not regular solid MIG wire. Sorry about the missunderstanding.
