"It starts with an exciting field trip", sculptor Frank Andrews said when asked about his process for creating these welded copper petroglyph sculptures.
"I hike into prehistoric rock art sites in the desert Southwest, take photographs and make drawings, then convert them into sculpture patterns in my studio", he added. "My raw materials are copper tubing and copper welding rod. I bend different sizes of tubing to the image of my pattern, hammer the pieces flat on an anvil, then assemble the figure by welding the elements together with an oxy-acetylene welding torch. The design is then coated several times with copper welding rod to build up a texture that replicates the texture of the original stone image."
