foot pedal, and I made the mistake of wearing skecher shape ups on day one. none of my welds were sticking or I was burning stuff up.

Well if you want to see mine you can see the slider thread or wait until I get something that is 100% mine, other folks did the welding on those, I was busy cutting and fitting and my buddy was helping with that too so it would be credit for others work if I put it here.

Why bother posting? Because there is a lot of pipe to plate work in this thread that is VERY impressive. I employ several welders and they are all more gifted and talented than I am by far. I got myself certified way back in the 80's and with a bit of warm up I can get it done, but I struggled a LOT with pipe to plate and I know what it takes to develop that talent and just wanted to say kudo's to those posting them up, some seriously respectable talent involved!

I'm running a build thread and some commented on this one from my build. I had to replace a frame section. These are 3/16 plates at a 90 degree angle. Miller 210 w/ .030 wire. I did run the sandblaster over it so it has a silver look to it.

Hello, Can I get some feedback on my welds? I think I've almost got them down but I'm not sure what I want to be looking at.

Base 3/16" with the T being 1/8"

Also, I am following the directions on the side of the machine exactly, in fact I was one 'thickness' higher (using Hobart) for more heat than suggested (with wire speed turned up according to the chart also), and it looks like I'm getting exessive splatter. That is a sign of voltage too high, correct? Either increase wire speed or decrease voltage to fix the problem?

Some of the 'bulges,' which are most apparent in the 'normal' speed stringers were tack welds that I ran the bead over.

Here are three groups:

Stringer, normal speed:






Stringer, slow speed:









Dimes, not tack tack tack, more like stop go stop go:







The 'slow' stringers look the best but I feel that I'm just moving way too slow.

The 'normal' stringers look alright, they have more of a convex profile than the 'slow' strings, but don't look as good.

The dimes look alright, Honestly I'm not a big fan of them, if I'm correct, they are more for looks right? What of the 3 types of beads do I have, have the best penetration in general? Do dimes have the worst penetration? Do the dimes have the least amount of strength? Thanks!

They all look pretty good if you feel like your moving to slow you can turn your machine up voltage/amps and wire speed and still keep the same quality weld..., the chart on the welder is just to get you close to the proper heat/wire speed... Just about every weldor will have different settings for the same weld it's just all what your comfortable with...
The "dime" welds are mainly just for looks but can be done with good penetration as well... You might want to try a few different weave patterns.... J's, circles, c's, whipping there are a bunch of different patterns you can try to get different looking welds....
They look good keep practicing

All of the welds look strong, some stronger than others. The "dimes" are the least strong, but probably strong enough for that particular thickness of metal. Of course, you can improve your technique on those, as youngjeepr stated.

The stringer beads, regular speed, aren't bad welds, but if we're splitting hairs, here, the travel speed is a little too fast. You can tell this by the shape of the "freeze lines". Those are the individual little curved lined that form as the liquid puddle is cooling. The freeze lines on these particular beads are a little > shaped, and should be a little more ) shaped. Slowing down will correct this.

The best quality welds, in my opinion, are pics 6,7, and 8. The freeze lines are the correct shape, the toes of the bead have good penetration into the base metal.

Like I said, they're all good. Just that some are better than others.

Keep on welding !

Various stuff i have welded. Two of them are weld tests the pipe is an AWS certification test i took just the other week (yes it passed) the other is just a layout test. some of those piece are 64ths in difference that kind of layout test.

Those are first class welds! Nice job!

One question, though, is that pipe test done? It looks like it needs another bead in the center.

No its not done it had to cool down it couldnt go over 400 degrees interpass temp. If you look close on the right side you can see where there was a temp stick mark on it that had melted on a 375 degree stick.

Gotcha...when we use temp sticks (I'm a nuclear pipewelder), we have to check the metal a minimum of 1", to a maximum of 3", away from the edge of the joint.
