Torchmann, a good gas weld is nearly indistinguishable from a good TIG weld. A "stack of nickles" is not necessary, but it is nice. Every once in a while when I've got a weld in a particularly visual place, I go for pretty, and usually get it. If you want to play with something, I stumbled on a pretty unique method for getting nearly completely flush "Nickle Rolls" and excellent penetration on thicker material...I call it the "Drip Method". This takes TONS of practice, and I find it only happens right for me when I'm in "zen-weld" mode. Using an aggressive and broad flame, I pre-heat and begin to feed the pool with direct contact of the filler rod as would be normal. Now, as the surrounding metal begins to really absorb the heat, and the bead speeds up,I begin to pull the filler rod back away from the pool while still keeping it at the edge of the hottest part of the flame. Now, I walk the pool forward while maintaining a steady drip from the filler rod. The timing and coordination have to be DEAD on, but the results are nothing short of art. I did joints like this on a square tubing engine cradle I built for a buddy of mine, and without any grinding or touch-ups, once the cradle was painted with a coat of black Rustolium the beads were nearly completely invisible.
