description The invention provides an alternating-current and direct-current dual-purpose high-blowing-force cellulose welding rod which comprises a welding core and a coating, and the coating comprises the following components in parts by weight, 2-9 parts of rutile, 30-55 parts of microcrystalline fibers, 3-9 parts of carboxymethyl fibers, 3-9 parts of iron sand, 3-9 parts of ilmenite, 3-12 parts of high-carbon ferromanganese, 2-7 parts of titanium carbide, 2-7 parts of titanium dioxide, 5-15 parts of marble and 10-17 parts of magnesium carbonate. The cellulose welding rod can meet the outdoor operation welding requirements of large long-distance pipelines, petroleum pipelines and the like, slag removal is easy, welding bead forming is attractive, welding arc blowing force and single-face welding double-face forming are guaranteed, the mechanical property of welding seams is excellent, the cellulose welding rod can be used for welding of the large long-distance pipelines, the petroleum pipelines and the like, and the w
