I want to make some wire shapes/sculptures, mainly out of straight pieces of wire, galvanised probably (can you weld that?) with a few pre-made circles out of the same material. Is it a matter of securing the pieces together and then tacking it together with the welder? Besides the usual safety measures is there anything I need to be aware of? Metals to avoid, or don't weld, easier to weld?
I'm only thinking of welding as I'd like to them powder coated after to finish them.
