...system is a “lathe” where the torch replaces the tool post. Automatic part handling and computer control of the torch can be used to improve the production rate and quality of the coating. Both processes are usually done in air, although the non-transferred arc process can be done under vacuum or inert gas for powders and/or components which oxidise readily. Processes...
