Welding on deeply pitted rusty metal

[sixdogs]

I use to have a stick welder, it's on my wish list, come's in handy on rusty steel. I find that's one of the draw-backs with mig, it like's shinny metal.

Just use flux core wire with MIG and no gas. It works great for me on rusty farm equipment and never a fail. I'm only an advanced hobbyist but it has worked for me.

sixdogs you wouldn't believe the amount of bridge, and over pass falsework that is built with self shielded wire. And nobody takes the time to wire brush the rust off the weld zones.

Thanks again for all the suggestions. Does anyone know if there is a comparable flux core wire to E6011 rod?

It looks like I may go Ryan's route. I am going to see what those small blaster require for air flow.

Nothing is comparable to 6011 stick in welding significantly rusted metal. The difference is the absence of the forced feed of MIG that requires a highly predictable condition. 6011 will blast thru heavy rust scale and give a good weld on the clean metal under it. It will weld anywhere you can get an arc started.

Lincoln's NR-211, and NR-212. Hobart's 21-B, are all good general purpose self shielded wires.

Yeah, that's with somebody like you welding it. I've seen pictures of your welds and we're pilgrims in comparison.

I have used the Lincoln flux core wire and welded some really sad equipment that would never be on the road and have never had any failure of any kind. Believe me, some of it should have failed. I did one emergency weld for an off road wagon with no metal for parts--just bolts pirated from other places to buy some time. I made the guy promise to get it fixed correctly immediately and to never tell who did the original welds---me.

Ten years later it's still pulling 12,000 lbs of hay, plus the wagon itself. Lincoln flux core and good penetration plus the stuff I learned here.

What is the downside of it? There are plenty of other rods available for other things but why not just use 6011?

Thanks! But remember I've been at this a few weeks now.

That stuff AKA spatter wire, welds like crap, but it works in a pinch, but the 71T.045 Duelshield flux core, welds smooth a silk and come's out smooth a butter. Still though, E6011 is what I'd rather use on Rusted/RUSTED steel, that's reason No.3 why I want a AC/DC stick welder.

Guess I should of read your post before I posted, DIDO.......
