im on overhead bevel plate useing a number 17 TIG rig with a #10 cup and gas shield 3/32 1.5 or 2% tungsten .plate is 3/8 running 120 amps scratch start i have tried every way to find the right spot short of standing on my head right now im laying on my back on the ground .im walking the cup and my problem is not enough rod or to much and i ram rod it im really thinking about useing my #9 flex head and free hand the thing to see if that helps any advice please before i blow my brains out
Reply:How about pushups ?It's tiring to keep your hands over your head like that, too easy to get tired and lose fine control
Reply:If it was easy anybody could do it and it wouldn't pay worth a dern. Welding is a skill that takes some considerable time to develop, you can't just pick up a TIG rig out of the blue and expect to be a golden arm in a week.

Reply:Tig welding is not difficult nor easy , like all other tig welding process has its own charm .with which wire diameter you weld ?
Reply:Blow your brains out. Scratch start is pretty tough, especially overhead. Then you have to break the arc and foul the rod, weld, and perhaps tungsten. I have done stainless steel vacuam chambers overhead with a customer's Miller Maxstar liftarc tig that way. I hated clipping the fouled filler every time, and having to grind out some of the contaminants at the break zone of the weld. Next time I showed up with my own Dynasty200 with 17 style torch, and CK finger control. Got the job in half the time, used less gas, and got paid the same. Walking the cup overhead, now that is talent.Weld like a "WELDOR", not a wel-"DERR" MillerDynasty700DX,Dynasty350DX4ea,Dynasty200DX,Li ncolnSW200-2ea.,MillerMatic350P,MillerMatic200w/spoolgun,MKCobraMig260,Lincoln SP-170T,PlasmaCam/Hypertherm1250,HFProTig2ea,MigMax1ea.
Reply:sory , but for that you begind with something you should think about how you should welding.a koker with 15 tig electrode in complete cut point , enough pieces of wire etcpreparation is half the work we say here by us
Reply:you act behave as if welding is very difficult , give me a monkey and I teach him the tricks of the welding and he is not complaining how difficult welding is .

Reply:overhead welding is tiring, you should look for a position where you can easily support your hands For example a chair, crate, or your back on the ground. make sure your back is always supported so you can easily relieve your hand. put your cup in the seam and the tungsten electrode should be deep in the back of the seam, if you add you have to add this in the back of the seam.I personally keep the wire into the meltingpool and start to peddle . First your meltingpool must be liquid. your toorst must be 80 to 90 degrees oriented. your wire has to have a leeway of about 2 mm compared to the opening, if your opening is larger your meltingpool wil go downwards and you do not want that.
Reply:Walking the cup in a bevel in any position is cake. Freehand is the more tedious in overhead (unless you've got a tig finger!) in my experience.If you're going north/south you're only making it harder (to position your hands, not to actually do the weld). Set up east/west or horizontally. Don't tack it so high that you're over extending your arms either. Right above your head to no more than 6-8" taller than you are is about right.It may help to "cheat" a bit and give the plate a slight 5 degree tilt upwards on the closer side. Make sure you're directly under the weld zone so when you look up, it's right in front of your eyes. Wrap your hose around your arm and go to town.I love scratch start. When you break the arc, obviously, do it off to the side on the bevel and not in the puddle. If you're sticking then shorten your stick out a hair, since you probably don't have room to angle the torch. Rest the side of your palm on the filler hand on the plate near the end of the weld zone where it's not so hot, hold the rod near the end and walk right over it. This is how I do it, anyways. May or may not help you. |
