I'm just beginning to play around with silicon bronze. I tried TIG welding some sheet (.065") and noticed that the bronze does not behave like any other metals I have welded (steel, stainless, copper). The molten bronze seems to be much more viscous with a much higher surface tension; it doesn't flow nearly as readily as the other metals and it has a tendency to pull itself into blobs. Is this just the nature of the beast, or should I be doing something different, like using a flux, or a different shielding gas (argon), or a higher gas flow rate (15 cfh)? Any tips or tricks? Or do I just need to practice more and learn how to compensate for these characteristics? Thanks for any suggestions.
