over head welding - Pirate4x4.Com : 4x4 and Off-Road Forum

iwishihad1 · 07-07-2010, 07:01 PM

hey everybody

Ive been working on some projects lately, and in a couple nights im doing some welding on a buddies jeep. ive gotten fairly decent at most positions I run into but have almost no experience with overhead stuff. any good pointers or videos i should watch

thanks

How critical is the weld? I would do the tack tack tack method (pulling the trigger for a good long count and make a circle motion, not just a quick tack), turn the welder up a couple settings past what you need and it will burn in good. I've done a lot of welding like that. A lot of people will say this method is shit but unless you are an excellent welder overhead welding is probably the hardest to do, especially if you are using a mig welder with gas. Or you can try small stitches, just try and stay away from long slow passes (tends to booger up and drip molten metal down your neck). Just my $.02.

most overhead welding I have done was about 40-60 minutes solid, one bead.

I ended up turning it up a little more and speeding up a little. Otherwise, welded like normal.

Just practice on some steel first.

Unless the wire speed and heat are money on my Linclon SP175plus, I get molten dripped on.

iwishihad1 · 07-07-2010, 09:07 PM

the weld is going to be for the frame end upper control arm brackets for a rear 4 link. ive done the front 3 link, tube fenders, and the rest of the rear, but these brackets are the last ones to go....saved the hardest for last i guess.

thanks for the help

Welded upside down with my MIG once, still have the 2 holes in my shoulder where I got goobered on with molten slag...

From then on out I just vowed to only weld looking down. Just flip the project over.

Or TIG.

Bump the wire-speed a smidgen, and watch the puddle. People overthink overhead welding, and it's just not that hard, don't get tripped up in your head.

I am seen and heard many people call anything that they have to reach above there head overhead .

Overhead is just flat welding turned upside down.

For any but the littlest amount it is time to break out the leathers.

Good luck it just takes a little practice.

yep that is the best way to say it i have never had a problem with any welds overhead or in the welding world 4F or 4G

LazyDog · 07-08-2010, 10:28 AM

turn up the wire speed just a little bit and push the puddle.

Having already burnt myself today, I'll say it's always time to break out the leather. Even in near 100 degree heat.

Take lots of breaks, stay hydrated.

Leave the voltage and wire the same as you would for flat. Only in overhead running dualshield flux core, I turn the wire up a bit.

sn0border88 · 07-08-2010, 08:03 PM

Your probably going to want to turn your volts up .5-1.5 from what you normally run, other than that its just like welding flat. The hardest part is getting in a good position.

You welded constantly for an hour overhead? On what? Ive got to wave a flag on this one. Its hard on the body to weld intermittent overhead for 15 min.

MC · 07-09-2010, 08:39 AM

We turn up the heat a little for overhead MIG.

stimie · 07-09-2010, 07:13 PM

What works for me welding uphill is an upside down V pattern and holding for a second on each side of the gap. But like others have stated your voltage and wire speed has got to be spot on hope this helps

johnmcd · 07-10-2010, 10:54 AM

Its a jeep, roll it over.

Booger Weldz · 07-10-2010, 12:36 PM

make sure the metal is clean(ground clean of mill scale, paint, oil, etc, etc) and the hot molten drippins will drastically be reduced...i push when welding over head, weaving a bit from side to side(not as drastic as vert up) and dont position myself directly under the weld. leathers are a given for your arms and shoulders, but my settings are identical to flat and horizontal welding. only when welding vert up do i change settings for a given weld type MIG process(i drop wire speed just a bit)

iwishihad1 · 07-10-2010, 05:34 PM

thanks for the suggestions

looks like ill be needing to find some protective clothing for this one

JeffsJeep04 · 07-12-2010, 03:46 PM

When I learned to properly overhead with an arc welder, my mig overhead that I never could get down magically just worked out...watch the puddle, relax your arm. Wear ear plugs.
