Well folks, had a chance to mess around with this whole thing a bit more today. GTAW didn't have results even close to the GMAW application. Couldn't get it to puddle up on top of the SS at all, instead, it just sheened off like water on a RainX'd window. Tried AC, DCEN, and DCEP, still pretty much the same result, wire is apparently the way to go if you're looking to have any way to control the deposits. Found out something else, if I increased the size of the pattern much the bead cracked into pieces. I was using .035 ER-5356 filler, this could very likely have contributed to the cracking issues. When I get a bit more time I'll try the same thing with ER-4043, a rough guess tells me that the cracking issue might go away. If not, I may need to apply a bit of preheat to the SS backing material so that it doesn't cool so quickly and maybe helps to limit the cracking.
I was able to weld various pieces of this together with very little trouble with GTAW, so this might support my intent to make up some 3D type stuff from various pieces. If I come up with something else I'll include it on here for you folks to laugh at. Best regards, Allan
