Some welding I did today

Got it, thanks

Couple questions
Splatter? What causes it and how can I eliminate or reduce it?

Ball on end of wire? Too fast wire speed or too little heat? or?

Should I be ashamed of these welds? At least around real welders?

Charley - weld spatter is caused by several variables, some of these are oil/foreign substance on the base material, position of electrode relative to the work piece, slope of current (amperage/voltage), and sometimes it just happens no matter what. I suggest try using different positions for the gun and change the amount of stick out.

Ball on the end sounds like you may have to much stick out or perhaps running to cold (low amperage) for the amount of stick out you are using.

Never be ashamed of anything you do but continue to learn all you can and strive to improve your talents everyday!

Not knowing what machine you are using are any of the particulars about the wire spec, size, amperage and voltage, it is hard to say exactly but I suggest trying different settings and practicing with different techniques such as forehand, backhand, pointed up and different speeds for any given material. The metal in the pictures is certainly heavy enough you could put many amps into it and as long as you are not undercutting the base metal you should be fine!
 
This is one of todays welds, didn't have time to take anymore. I'll get some more pics after they are tumbled too.

Charley,

Try slowing down just a tad on your oscillations and use a small circular motion that just overlaps the molten puddle over the frozen puddle as the weld progresses. All in all the weld looks more uniform than the first pictures and it would be way easier for me to show you what I am thinking than to tell you in writing so I hope you understand what I am trying to explain.

Good Luck,

I hope to be able to make welds like that someday with my Hobart 140 that the wife bought me for Christmas. :)

I'm not swirling as much as I'm going forward then backing up a little then advancing forward repeat. A guy came down over the weekend and welded a sample (wish I were there) Joey (the owner) said he just went forward and back like that, his weld looked as if were done by a robot. I will take a picture today & post it of his and some more of mine. Thanks for taking the time to help.


Roy, You will just takes some practice and guidance. That little Hobart is a pretty nice machine, I almost bought a bigger one a few months back but the guy wanted as much as I could buy a new one for. I have a Millermatic 140 and love it for it's intended purpose. I'm assuming yours is a gas version also. Weld some stuff & show us some pictures and somebody will help you.
 
Here are some more pics including some of the welder and another guys weld that's been welding his entire life, see if you can guess which one is his :lmao:
