Critique these welds

admin

Ok guys, I'm posting these because I think it's an accurate reflection of what I can do at this point. I'm not saying they are great, but I think they look ok, aside from penetration. By looking at them, i think there may not be adequate penetration, but I want some feedback please. I used the circular motion on these, except on the fillet, which I think I dragged back and forth. Welded on a lincoln power mig 140c maxed out with wire speed just below 3 of 10. C25, .030 wire. Thanks in advance. And I won't be sensitive to the criticism.
Reply:first and third look good. Second is very cold, with minimal penetration at the begining of the weld. Might have some penetration at the end of the weld when the material finally heated up.There are no problems. There are only solutions. It's your duty to determine the right one.Hobart Handler 210Airco 225 Amp MSM Stinger
Reply:Thanks. Would turning down the wire speed be enough to give me more heat on the fillet?
Reply:I notice you did remove the millscale from the on the angle where the weld was going..But the angle that was welded to the clean piece was not cleaned on the edge where the weld goes.Clean everywhere a weld will be..Look at it like it's welded before you start and figure out where the weld will be and clean those areas.You will see improvement....zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:Thanks guys. I cleaned better and upped the wire speed a tad actually, but tried to steady my motion. How's this?
