Abstract

667,905. Uniting by fusion. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Feb. 16, 1950 [Feb. 19, 1949], No. 3989/50. Class 83 (iv). A coated welding-rod for electric arc welding comprises an iron core and a coating containing powdery iron so that the total amount of iron constitutes from 75 to 86 per cent of the total weight of the coated welding-rod and from 15 to 50 per cent by weight of this iron is contained as powdery iron in the coating, the'rest of the coating substantially being of the following composition by weight: titanium dioxide 10-50 per cent; carbohydrate 10-30 per cent; silicate 20-40 per cent; manganese alloy (e.g. ferromanganese) up to 10 per cent; manganese compound capable of evolving oxygen at welding temperatures 3-30 per cent. The manganese compound may be hausmannite, potassium permanganate and brownstone used singly or in combination. The manganese alloy may be omitted provided the coating contains 18-30 per cent by weight of carbohydrate and also manganese compound from 12-30 per cent. by weight of carbohydrate and also manganese compound from 12-30 per cent by weight of the non-ferrous constituents. The thickness of the coating is such that the diameter of the welding- rod is at least 1.3d+1.0 mm., where d is the diameter of the core.
