Climax Portable Machining and Welding Systems says its AutoClad machine is an innovative system for cladding the inside diameter of nozzles, tubes and other circumferential components for protection against corrosion from caustic chemicals, or erosion from slurries.

Usually manufactured from mild steel, these components can be clad with a protective material such as stainless steel or a nickel alloy to provide corrosion resistance. Although most welding processes leave voids where corrosion can damage the base metal, AutoClad provides void-free welds by combining GMAW welding with automated axial feed and rotation of chuckable parts. Work pieces can be clad with stainless steel, Iconel, or other exotic metals at a rate of up to 5 lb (2.3 kg) of metal per hour, reducing weld times. The machine rotates the work piece, features an automated axial feed that uses a “step” process for precision bead placement and complete weld coverage, offers independently adjustable parameters that allow the user to control the bead thickness, and permits the travel carriage to be disengaged for rapid re-positioning. www.cpmt.com
