I need some help with inside corner welds with a stick welder, for the welding class I'm taking. Does any one have some tips tricks or advise?
What kind of material? How thick? Right angles? What kind of rod are they letting you burn? Most schools make you use 6010 when you first start out. That rod sucks but you learn technique fast. I prefer 7018 myself. Do you have to weld uphill in these corners or are the welds flat and straight out?

Thanks for steping up Scott, we gotta help the boy!
This is at the high point, now I'm just being cocky... Having coffee 25' up on a ladder in the mud. I was trying to show my employees that stuff has got to get done, one way or the other.

I usually use a 3/32 or 1/16(don't know for sure) inch thick steel plate held at a 90* angle with a right angle magnet. I usually use a 6013 rod, and I usually keep the rod at a 45* to 60* angle.

3/32 seems a little small for 1" plate
6013 is a farly smooth burning rod but I prefer 7014

With 6013, I would strike the arc and then touch down with the rod until you can feel the material that you are working on (this needs to happen within a second or two) and then drag the rod out from the inside of the corner. Drag it just fast enough to make the weld puddle look like a half moon. Too fast and it gets pointy, you don't want that. One thing that might help you since you are just starting out, take a rod and cut it in the middle or burn it down half way and then weld your parts. A new, long piece of rod is more difficult for a new welder to control. The half lengths are easier to steady and will help you get your control down. After a while you won't think about it and you'll move to long pieces and have no problems.
If you can get them to let you burn 7018, you will throw rocks at the 6013 salesman the next time you see him. Burning 7018 is like riding in a Cadillac.

I've fallen from nearly that high before (20') when a ladder pretty much like you're on kicked out at the bottom. The rubber feet were worn off and I had no business using it. It was 6:45 in the morning and I was on the job all by myself. Broke my pelvis in 5 places and had numerous other injuries. After I got my nail bags off, I lit a cigarette and thought, man are you ever in trouble. After about 10 minutes I got up and tried to walk to my truck. Yeah, right!! You do not walk with a broken pelvis.
Ouch Mark, that has got to be painful. I watched my roofer fall from just 8 feet, and broke his shoulder and pelvis. He screamed so loud... I could almost feel his pain.

I think my teacher has 7018 I will have to try that because Friday is the end of the quarter and I got 2 more inside corner welds to do. It took me the whole class priod to get 1 inside corner weld done. Would welding closer to the corner on the joint help much?
