ABSTRACT:
An apparatus comprises a conveyor for conveying works held to its support members with the desired surfaces of the works to be treated closely arranged in a low; preheating gas burners arranged below the path of travel of the desired work surfaces to heat the works from below during travel; a first metal spray nozzle, a second metal spray nozzle and a fusing nozzle which are arranged in such order above the path of travel of the work surfaces; and heat-resistant metal disks provided beside the metal spray nozzles respectively, each of the disk being rotatably supported and so inclined that the lower portion thereof exposes the desired work surface only and shields the other work portion from the metal spray nozzle. The disks are rotated during spraying operation by drive means. Melted metal such as self-fluxing alloy, etc. is sprayed onto the desired work surfaces only, while being prevented from deposition on the other work portions.
