Abstract

The invention discloses a potassium titanate welding rod material and a preparation method thereof. The welding rod material is mainly composed of components of, by weight, 50 parts of potassium carbonate, 40-60 parts of titanium dioxide, 1-7 parts of carbon nano tubes, 5-15 parts of kieselguhr, 1-9 parts of tungsten carbide, 2-8 parts of chromium carbide and 0.5-1.5 parts of nano silica. Compared with the prior art, the welding rod material is used as an additive of welding chemicals, the advantages of both good mobility and high anti-moisture absorption property in the prior art are achieved, most importantly, arc voltage can be reduced apparently, arcs are stabilized, spattering is reduced, and the content of sulphur and phosphorus of the welding rod material is reduced apparently.

Description

technical field [0001] The invention relates to a potassium titanate electrode material and a preparation method thereof, belonging to the technical field of new materials. Background technique [0002] Various filler metals in the welding process and additional protective substances to improve welding quality are collectively referred to as welding materials. In terms of the use of electrodes, the United States currently mainly uses titanium-type, high-fiber and low-hydrogen electrodes. In order to improve the deposition efficiency, a certain amount of iron powder is added to the coating of titanium-type and low-hydrogen electrodes. In Europe, there are mainly titanium-type, titanium-calcium-type and low-hydrogen electrodes, but the proportion of low-hydrogen electrodes in Northern Europe is relatively high, and like the United States, high-efficiency iron powder electrodes are developed. The electrode coating types used for low carbon steel in Japan are mainly ilmenite ty...
