Art Casting With Sculptor David Perrett - Part 3

This video covers day 3 of working on a big art casting project with/for local sculptor David Perrett @davidperrett4164. David's sculpture will be a boulder that has been chopped into 20 blocks and reassembled, with half of its stone parts replaced with cast aluminum, in a checkerboard pattern. I'm helping out with the molding and casting side of it.

What's the really dark sand, is it burnt petrobond or something else? Have y'all welded al. castings before? I heard it can be rly hard? Regardless, very impressive work 😊

The black sand is just well-used petrobond. I haven't welded anything other than mild steel using a fluxcore welder, personally. But you can see here that David is able to TIG weld the cast aluminum somewhat, without even really cleaning it very carefully. He says it is indeed difficult, but so far so good. He'd gotten one full block successfully welded together so far, last I saw.
