Stainless steel welding rod improving vertical welding process performance

The invention provides a stainless steel welding rod improving vertical welding process performance. The stainless steel welding rod comprises a stainless steel core wire and a coating wrapping the surface of the stainless steel core wire, the coating is prepared from the following raw materials, in parts by weight, 30-40 parts of rutile, 3-8 parts of zircon quartz, 5-10 parts of feldspar, 10-18 parts of marble, 2-6 parts of fluorite, 2-8 parts of dolomite, 1-5 parts of magnesia, 1-5 parts of aluminum oxide, 5-10 parts of electrolytic manganese metal, 5-10 parts of chromium metal, 3-6 parts of ferrotitanium, 2-7 parts of iron powder, 1-2 parts of sodium alginate and 1-2 parts of microcrystalline cellulose. According to the stainless steel welding rod improving the vertical welding process performance, the excellent flat welding process performance of an acid coating stainless steel welding rod is reserved, meanwhile, by designing the coating of the welding rod, the welding rod melting rate is reduced, the sla
