Downhand welds on Edges

by Rob
(Moose Jaw, Canada)

Where I work, we run a lot of downhand welds... more so than vertical up welds. Never on anything thicker tank gauge, unless it has a wicked gap or requires more than 3 fill passes (3/8'' wall plates gapped about 3/8''). On gauge it works well because you can catch the edges and watch it burn in real nice, without warping the material. On the heavier stuff though, don't even bother... I've actually gotten a scraper behind a downhand pass and peeled it out of there. Like you said, the weld puddle gets out of hand and kind of 'floats' away from the penetration point.

under cut with short welds
by: struggling

I have welded for over Five years mig stick flux , I have got my dream job now .but I am struggling with short welds with out cutting into the corners (undercut) all welds have to cosmetically perfect as well as strong of course . My trainer says all other welds are great . but the undercut could send me out the door if not fixed quickly . think of welding the end of 1/2 plate edge .and tying in the welds at the corners with out getting .01mm undercut is too much . should I build up corners before welding . any suggestions would be appreciated thanks ...
