More of an experiment with my iPhone video, to see if I can display weld beads better than using my still camera. Could not get it to upload in HD so I had to settle for standard definition. I realize the beads on the left side are probably slow and cold but I was slapping these beads on so that I could get some experiments done with my iPhone.

Reply:I think that worked quite well as far as getting a decent look at the beads overall. Only down side I might see is that I'm not sure how I'd capture a single pict if I wanted to make notes on something and post it. I know there's a way to do that, I just don't know how. I'd agree you could have run a bit faster on the left and tightened up your motions a bit more. Beads on flat plate, especially vertical always look a bit tall and humped though. consistency definitely needs work on the left bead. The toes don't look too bad, so I'm guessing your amps aren't too bad. Maybe a tad higher if you can handle it. It seems counter intuitive, but many times higher amps makes things a bit easier than when the amps are lower. I can't give you good numbers off the top of my head since we typically use 1/8" rods vs 3/32" ones. Right bead looks quite nice. Bottom is a bit colder looking than the top. My guess is this has more to do with your travel speed and rod angle/arc length than with amps at the very beginning, looking at the majority of the bead. Consistency is better than on the left hand bead. I'd like to see it a bit better, but I've seen a lot worse. It's tough to get really nice straight consistent beads without any references sometimes..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:When we were doing 6" Sch. 80 branch and header in school, we'd run a 1/8" 6010, but a 3/32" 7018. Amps were 95 for each, never changed. |
