Here is analogy of my attempt. This just padding beads on 3/16" MS...not worried about making pretty welds... just trying all amperages, different gas flows, different travel speeds, different filler materials, letting it cool between passes, quenching...etc.. Anything I could think of to control heat and color. ER70 S2 had no color. I tried 347 SS...little bit of color, 309..little bit of color, 316..little bit of color.. 317...little bit of color..Color is achievable but is not controllable in any way, at least with what I tried. The flash washed out what little color was there but the SS fillers showed way more color than MS filler did but still nothing close to the fabulous colors those artists achieve. The micro torch theory is sounding a little more plausible.
