Are my welds any good?
Yes they can. Visual inspection is a legitimate weld inspection as per the American Welding Society. Usually requires someone with no worse than 20/40 vision. Though welding gauges do help.I'm not the nice guy in the bunch, I'm not the expert welder, but.....can anyone who REALLY KNOWS WELDING.....see sufficient penetration?
Looks like a surface bead of crap to me.

What rods you using? As much as I hate stick welding, I usually use 6013. At times I would like a 7018, but since that's a low Hydrogen rod, a 7014 will be off the same strength.
using 6013 rods, i dont think they make 7018 1/16 inch rods but i could be wrong, i know ive never seen them though. ill probably pick some more rods up tomorrow, someone bought my kart for 250 so i can get steel too.
Yeah I know. We did that with all our rods in college regardless if they were low Hydrogen or not. But to me 70,000 strength is 70,000 regardless of composition. That's why I said a 7014 and 7018 besides being a bit different for all intents and purposes they are close enough. Also if one does use a low Hydrogen rod and not heat it constantly for storage, they should only buy the smallest amount they can and use it up, other wise in a way it does become like a 7014, at least that's what my instructor told me in college.Based on just the photos provided, I'd tend to agree; if it was a properly prep'ed V joint we'd see a root penetration bead on the underside. I'm willing to cut the OP some slack though, because he's A] being polite, and B] he's trying to learn.
7018 is stronger than 7014 due to the fact that it's low hydrogen. That being said, it takes a lot of effort to keep 7018's rating if you don't use it every day, the most important being keeping it dry. Not "I store it on a shelf in the garage" dry, try "I keep my rod in the rod oven at at least 250°F at all time's to drive off moisture" dry.
That being said, I'll take 7014 over 6013 anytime. The only thing 6013 has going for it is ease of striking and keeping an arc going. Its cleaning action is non existent, its penetration action is almost as bad, and it excels at slag inclusions.
Crash course in welding rod size selection; when using a small machine on small cross sections of material, USE EVEN SMALLER DIA. RODS!!!!! Case in point, 1/8" thick material, use 1/16" (or smaller) dia. rod. You have to match the rod size to what your material thickness, as well as your machines output and your actual skill set.
^^^^ This is why I'd never claim to be a welder.
I can usually stick two things together though.
But I'd be willing to bet, a guy would have a heck of a time knocking the OP's bead off with a hammer.
