I'm in the jungle of Venezuela and welding on a friend's metal boat. It's a canoe shaped boat make with an angle stock frame and then probably 3mm steel sheet bent over the frame and welded to the frame. The boat was neglected and in some spots about half the thickness of the steel has rusted in big flaky sheets and has come off. In the remaining metal where it's thin and also in some places where it's still full thickness the rust has eaten through in cone shaped pockets making small holes that I can usually weld around the edge some and then come across the pocket of rust to the other side and back to the center and fill it in with one quick weld. In some spots there's longer scratches which rusted deep so I'm needing to weld a bead which is a number of inches in length. In both types of welds I'm geting strange dimples or pockets and the bead is also thinner and flatter where I end the bead even if when I get to the end of the weld I do a few circles to fill in and finish the bead. I'm not a professional welder but I have some experience stick welding, mostly AC welding in the jungle with poorly stored rods but also some experience with a nice three phase 440v DC stick welder, boy that was a beauty. That machine made me look like a good welder, but it was the machine.
Anyway, I'm using a Lincoln AC welder with 1/8" E6011 rods with the welder set on 75 amps, sometimes going down to 60 or up to 90 amps as the work warrants.
I'd love it if people could tell me what I'm doing wrong. Be brutal. I want to know.
