It takes time, lots of time! Look at me, next Tuesday will be two whole weeks of welding!
Got any vertical up gems of knowledge?

For uphill welding you can practice moving your rod in a straight up and down motion without the welder on. Concentrate holding your rod steady and stepping up and then backdown into the puddle. You want to deposit some molten metal, then step up with slight long arc to allow the puddle to cool then back into it to deposit more metal, repeat. When you are comfortable with tracking your rod in a straight line with step method, then try it with the machine on.
In your photos, you are stepping out of the puddle too far. Try to tighten up the distance about half of what you are doing now. The ripples should be uniform and close together not more than 2 mm or about 1/16" apart. You want to step out just far enough for the puddle to cool just a bit.
Same thing with your weave on 7018 except dont step out of the puddle- just weave in zigzag method. Make your zigs and zags closer together. Most problems with 7018 are due to making 1 widezigzag rather than 2 or 3 in the same distance.

Practice just straight step up and down till you get the speed of travel down. That is the basic root pass and hot pass position for uphill 6010. The modified box (across and up the sides and back down) is a fill technique for filling a groove with 6010. If you are welding a large gap with a backer plate, then the box is your way to go. Dont go up too high on the sides, just enough to get out of the puddle then come down and back to the other side. Basically it isnt really a box but a horseshoe as the puddle droops a bit in the middle so it isnt really straight across bus a kind of half circle that you keep going back and forth and up a little on each pass about half the width of your rod up each time.
That is the hardest thing to learn with welding is the 3 dimensions that you have to control-- left to right, up and down and moving in all the time as your rod gets shorter and shorter. That is why MIG is so much easier. ROD length is always the same so you only have to work side to side and up.

It is hard to just tell someone how to weld. Best to find a good welder and watch him weld to see how he handles the rod, then let him watch you and correct you as you go. That is why welding schools exist. You need hands on and a pro to correct you just like in golfing. If you just keep on doing it without any instructions, you will get better to a point and then stall at that poin. You may develop some bad habits that likely will be hard to break later.
So if you cant go to a welding school, try to find a good welder that can spend just a few minutes with you on each technique. Welding schools start out with easiest position and progress to the hardest with 1) flat, then 2)horizontal 3)vertical and finally 4) overhead position. As you master one, then you move to the next difficult.

As a boilermaker, I would have to agree with Gary. We only use downhand 7018 for seal welds on skin casing. Welding is a process of function not cosmetics, some of the worst looking welds are still extremely strong, if you want pretty welds IMO use whatever you are most comfortable with and put a 5" cap on it(grinder)!
