DEFINITION

Classification: 427/59

(under subclass 58) Processes for coating processes producing electrodes used in electric welding.

(1) Note. Many of the patents in this subclass are for processes of coating consumable metal electrodes with a flux coating. Where the coated welding rod may be used in either electric or gas welding processes, the process of coating is placed in this subclass unless all the claims are limited to the use in gas welding.
