Welding Electrode Sodium Carboxymethyl Cellulose used as glaze slurry in the ceramic coating of electric welding rod, so the ceramic has the good bond property and brushability, meanwhile, CMC can be burnt under the high temperature without residue. Welding electrode CMC is added to the mixture of welding flux components to act as a binder. Welding flux is a chemical cleaning agent, flowing agent, or purifying agent. It is used in welding to facilitate the welding process by removing impurities from the welding surface and protecting the weld pool from atmospheric contamination. It can improve the appearance quality and eccentricity of the welding rod and reduce its damage rate.
