The invention concerns a welding electrode consisting of a core and a coating. The core wire consists of an austenitic stainless steel, which contains in weight %: 0.001-0.03 C, 0.01-0.3 Si, 0.5-2.5 Mn, 19-21 Cr, 9-12 Ni, 0.01-0.2 N. The coating contains in weight %: 6-10 CaCO3, 2-5 F, 10-30 SiO2, 4-10 Al2O3, 25-35 TiO2, 7-12 Fe, max 5 CrN, max 5 Ni, max 10 Cr, max 5 Mn, balance essentially only sodium- and potassium compounds existing as components and natural minerals; binding agents; and unavoidable impurities. The invention also relates to a welded article of an austenitic stainless steel, a new austenitic stainless steel and a welding wire made of such steel. |
