Welding Pastes are special chemicals used to clean and protect metal surfaces during welding operations. These fluxes are designed to prevent oxidation and ensure better bonding of metals during the welding process. Typically acidic or basic in nature, welding fluxes are applied to metal surfaces to aid in the removal of residues and contaminants. Additionally, they create a protective layer on the surface to enhance the flow of the weld. Welding fluxes are commonly used in the automotive, metalworking, and construction industries.
