Reply:Would you belive... 1" X 3" flat bar with a John Deere AC buzz box.......  It was for a snowplow attachment on a Unimog.  I had to put a 90 degree 4 inch tang on the end so that It would drop the main frame lower.  Then when It was lifted up, there was some ground clearance, for the blade, and the main frame still cleared the bumper, in the fully lifted position.  I cut a 45 degree angle on both pieces, beveled them with a torch and grinder then made 3 or 4 passes on each side using 6011 rod.  Not sure what ampreage, (It was a long time ago)  prettiest weld I ever made.  When It was done, the beads looked like they were braided together.       Since I was always noted for overbuilding, I had also welded a short gusset, which I'm sure gave it the strength it needed.  As well as angle iron cross braces.  We tested it out on a really big rock that we found frozen into the middle of the road one day.  It just about knocked my teeth out when we hit it.  I figured that if that rock didn't break it, nothing would.  I talked to the farmer 10 years later, and asked how the snowplow was holding up.  He said the Chanel Iron that  I used to hold the hyd. cylinder bent from the weight of the blade.  He hadn't told me that two years after I built it, he had a fab shop weld a piece of 10 gauge plate to the top of the blade to stop the snow from blowing over the top.  Talk about a weight increase.  But that 1 x 3 flat never did break or bend.Lincoln 225 AC/DC, Hobart 140 Mig. Oxy/propane Victor torch.(2) Makita 5" angle grinders  one with zip disk, 14" chop saw.  and just about every other tool you can think of. Whoever has the most toys when he die's ..... Wins!
Reply:wow you guys have some big iron experience, the biggest i've ever touched was a 10" x 50" x 40' slab where my dad works, they had a tour i went on.  Sometimes i like to just look a thick piece and just imagine what all it could be turned into and by what. My Grandfather worked at Uss, And my dad is still there, It's kinda cool to think i am the third straight person in my family to have steel in my blood!!StangnetShop Full Of Stuff. Joey

Reply:From sheetmetal to 6" plate on a daily basis.  Working in a fabshop, you never know what is around the next bend.Common sense in an uncommon degree is what the world calls wisdom.
Reply:Thickest ever was 1".   Latest work was with 1/2" plate using 7024 @ 3/16" for beefing up the floor of a on site dump trailer.Here in the Great White NorthMosquitoes can't fly at 40 below
Reply:i have welded plate from 8"to1/16" i worked for a heavy hauling and heavy lifting company called davenport mammoet they haul and lift things that weigh over millions of pounds
Reply:I hate welding on that stuff.  To a newbie it might sound great, but its frickin boring, ranks right up there with pickin fruit for a living. I would rather haul a bundle of rebar over my shoulder most of the day.www.urkafarms.com
