Inquiry (采购产品): large alum welding Hi, My name is steven osolin, I am an NC programmer at a Fab-Machining house in Massachusetts named Ranor, Inc. I was wondering if you had ever welded large diameter (in the 10 ft range) thick (4-5 inch wall) aluminum rings or cylinders and if so what was your experience with shrinkage. Any and all technical information you could supply me with in this area would be greatly apprecieted, thanks in advance, steveo. **** Hidden Message ***** steven osolin 1 Bella dr. westminster, MA 01473 USA Company: Ranor, Inc.
