Root Pass 6011

admin

OK so I have to do a root pass on 3/8" plate beveled at 30 degrees 1/8 land 1/8 gap with a 1/8 6011 rod.  How would you all suggest I run the root ?  I have been using a whip and pause motion at about 75 amps.
Reply:I ain't no pro.  My experience with 6011 is basicly.  Run it as hot as you dare, figure at what temp., and speed, causes a burn thru.  Modify.From what I understand, 6011 us a time honored rod known for pretty healthy penetration.  I never could master it.  Now I mostly use it for fast repairs on rusted metal.Speakin' of time honored.  Used to tease my dad, when he was alive.  Man, you guys were tough enough to win the war.  Had to be, runnin' in those damn boxer shorts."Any day above ground is a good day"http://www.farmersamm.com/

Reply:right your heat should be about 80 watch the keyhole keep it centered if it gets too large step out further or manipulate you drag angle to a push angle to take the heat off the root bead. or do a combination of both if too small increase your drag angle and travel slower.if welding 3g or 6 g use about a 5-10 degree work angle from the axis of your root this avoids undercut on the root pass, careful of suckback at tie in's at the tacks always feather edge tacks and stay long enough there to deposit weld metal. starts and stops burn in by holding a long arc at the start then push your rod in.oh and your land should be 3/32 and your gap 3/32 "nickel land nickel gap" a 1/8 land is going to give you hell if it's fit up that way turn your heat up to 100.Last edited by ian_s; 10-24-2008 at 02:42 PM.
Reply:another thing about uphill root passes if you step out into the root it works the only drawback is that you deposit weld metal into the root and it gets difficult to work your rod past it i can usually just melt through it but if it gives you too much problems then you can whip out onto the bevel up and to the right holding a long arc (so you don't carry any metal on the bevel) over the bevel while your root bead cools. if your welding 6g you want to go up and to the left because up and right is going to put your heat on the root.another thing that works is to bend your rod in 1/2 90 degrees and use the shorter rod you can use this with a hand position where one hand is on the pipe and the other holding the stinger is laced with the hand on the pipe at the thumbs this gives you good control of your work angles and your whip.Last edited by ian_s; 10-24-2008 at 03:25 PM.
