Hey all,
I'm contemplating a sculpture that will involve one component fabricated from sheet Silicon Bronze... for those not in the know, this particular bronze usually comes in 24" x 120", although I HEAR that I can order it from time to time in a 4' wide dimension.
This piece may have a total dimension of 15' high by 5 or 6 feet wide and I don't see doing it without seams. The trouble is, Silicon Bronze distorts like nobody's business when under the torch (even Pulse TIG). I'm afraid that even if I stitch weld it together using
1/4" length welds and let it cool between passes, it's STILL going to warp.If I DO make this in the size I want, I can go with 3/16 or 1/4 inch material, if the total cost doesn't scare the client away.
Any suggestions on keeping this sculpture from twisting into a knot when I weld it up?
Thanks,
James, Seattle
