About LinkBacksWas practicing with some scrap tonight... about to head back out there. Right now my biggest issue by far is porosity. I've been griding all the steel quite well, I think it's my technique. More practice!

Your bead form looks good looks to me you are moving a lil slow and putting in to much heat
what size cup and gas flow are you using ? amperage ?
you can wipe the surface down with acetone to remove any surface contaminants

3/32" Lanthanated with #6 cup @ 15cfm. Not sure on amperage as I wasn't able to set the max on the pedal (working on this).Originally Posted by WeldingWookie
The steel pictured is around 1/4" thick. I don't think it was undercut at all, but I could be wrong.

i don't see any undercut.. what i meant by to much heat is the weld color from to much hang time in the puddle before moving forward

Ah, I see. This is the kind of advice I need
Just heading out now. I'm going to try some new things - it's just so hard to change just ONE thing and keep everything else the same :S
Keep the criticism coming!

also if you leave the torch over the weld zone as the post flow timer runs it will shield the weld as it cools leaving no heat marks

steady and fairly consistent..... the porosity that yer seein right up front seems to be surface contaminants. a squirt of either rubbin alcohol or acetone and a wire brushin will help to clarify that...
