This video will show the spray welding process I use to repair a badly worn bearing journal on a shaft out of a Decanter Centrifuge, used to extract edible oils from solids. The equipment I use is the Eutectic TeroDyn 2000 used with oxygen/acetylene, and the ProXon 21021 powder. I'll share the entire repair process including tig welding the groove that was cut into the shaft, setting up in the lathe, flame spraying, and finishing back to size.
