Welding material

Welding material

Welding materials include over 200 types in three major series (solid welding wire, flux cored welding wire and welding rod). Products are developed to high-strength steel, heat resistant steel, stainless steel, nonferrous metal and other special welding materials on the basis of conventional application. Products are widely applied to steel structure, ship, pressure vessel, petroleum pipe, rail transit, marine engineering, nuclear power and other industries.
