I did that, instructor made us learn to weld overhead left handed.

Try it standing on your head with the hired man holding your legs in a 35 mph wind ;-)

7018 is a low hydrogen rod with 70.000 pound tensile strength. In my opinion, it's the best rod going for carbon steel. Good practice is welding an "I" beam butted into the flange of another beam. you get the Flat, Vertical, and Overhead positions covered. I spent 20 years welding cryogenic transport trailers, (Airco, Linde. Air Liquide) and even built pumper rigs for the fracking fields. Favorite process is Tig, stainless steel and aluminum. really relaxing! Just remember, if a dumb ass like me can do it, you can do it better.I couldn't have said it better,whatever the hell that meant

Wonder how much underwater welder are making these days??

May really consider that! Currently I don't own a welder and waiting until I really have a use and the $$ to buy a machine. I am traveling and with the 6 hours of class on Friday nights my time at home is too little. But may be able to help out when I can. Could always use more time under the hood ..

You did not run a 6011, 6010 or a P5 as a root bead?7018 is a low hydrogen rod with 70.000 pound tensile strength. In my opinion, it's the best rod going for carbon steel.

I saw a guy weld an entire trailer together with only 6011's about a year later I saw him. He said, well I should have run a pass over the 6011 with a 7018. Said in a few runs with the trailer going down the road it started coming apart. He had to flip the trailer upside down and re weld the entire thing with 7018's then!

This may sound odd but a great pipeline welder taught me this right out of welding school. Keep a pen or pencil in your truck. When ever your stuck in traffic or in line at a drive through. Take your trigger finger and middle finger and bend them in. Place the pen between them at the 2nd joint. Now practice welding strokes like a weave beed or a figure 8, or even a streight beed pushing your rod NOT pulling it as to pre heat your metal before the flux arrives. This will drastically improve your beeds. So practice welding your dash up!

Different techniques for different processes. Given the little experience I have 6010 electrodes are deeper penetrating and a good practice is a whip and pause.
With gtaw or tig welding where filler materialis used its about controlling the arc with the addition of the filler material.
My favorite so far is flux core wire fed with a cleaning gas produces a strong clean weld.
As far as why welds break especially with a deep penetration electrode can be caused by many factors porosity, slag inclusion etc... The 7018 usually provides a cover pass to seal the weld. Again I am only learning but I am soaking it up like a sponge

you are correct about the Mig. I run Flux core with 100% argon gas. it.s probably the easiest weld to master. First thing my welding teacher taught me was to braze plates together using Oxygen & Acetylene with a brass flux rod. then I moved to Arc, fist welding down then after that was mastered, to vertical then overhead. Then I moved to Tig using a rod brazing method, not a wire gun. Then last I learned to Mig. The course was 18 months. BTW, auto flash helmets at the end of the day will screw your eye's up. Specially if you are striking an arc alot. There is a slight hesitation from when you strike the arc to when the shield darkens. Over the corse of 7-8 hrs of welding you can actually burn your eye's. I use 2 helmets. One a old school pipeline hood. The other a pipeline hood mounted on a hard hat. I change out the lens from a #10 to a 14 depending on what style I am welding arc or tig. But Paul you will never flash blind yourself with the old pipeline hood. Just don't strike an arc before dropping your hood. One other thing is your gloves. Instead of the bulky welding gloves pay a little more money and get some elk hide. They cost about $20 more BUT, you have a better grip on your leeds. One other thing. If you get a arc welder get a stinger for the pos. leed 8' long.

When you can walk up to a job, pull the right rod knowing your metals, know when to gas, when to tig, when to mig, when to braze, you've made it half way. The last is penetration. Everything else is just a bead, IMO. I can't weld for shit, where I can almost braze. I love my tanks, my rosebud, and a fresh tube of braising rod bought a few months ago and already broken into.
Looking Really Good. Slow and steady. No fat buildup at any one spot. Lifer, how's penetration looking at it from your end? Heat [bluing] spread is narrow. Where bluing is a horror story right now going on. This poor guy had an old friend weld his wannabe replica bike. Bought a period kind of gusseting kit for the frame. When I saw the heat applied to that frame!!! And not even close to Paul's welds. Sad.
Anyone been to Barber? See the braising job on that Lotus frame hanging on that pillar? The britrivia goes; crash, I heat the braise and melt it off, replace the area with straight tubes again, go back out and race all in the same day.

I worked a pipeline one winter in 2 1/2 feet of snow with wind drifting snow.

No, just good bevel prep to edges .
