Problems solved by technology

However, with the development of science and technology and industrialization, the requirements for welding performance of weldment products are getting higher and higher. Traditional electrode additives still have shortcomings such as high arc voltage, large dust generation, and high sulfur and phosphorus content, which cannot meet this requirement. Therefore, the research and development of electrode additive materials with better performance has very important application prospects and outstanding significance.

Abstract

The invention provides an arc welding electrode additive and a preparation method thereof. The arc welding electrode additive is prepared from raw materials in parts by weight as follows: lanthanum nitrate, nickel carbonyl powder, iron acetylacetonate, corundum powder, indium powder, titanium hydride, praseodymium oxide, pentaerythritol stearate, sulfamic acid, formaldehyde modified lignin, polyisobutylene succinimide, potassium carbonate, methylnaphthalene, fumarate and tannic acid. The tensile strength and yield strength of an electrode prepared from the arc welding electrode additive are excellent, and the electrode has good impact resistance; besides, the arc welding electrode additive contains little sulfur and phosphorus, produces little dust, can improve the welding performance of the electrode and has excellent combination property.

Description

technical field [0001] The invention belongs to the field of metal materials, and in particular relates to an arc welding electrode additive and a preparation method thereof. Background technique [0002] The electrode for arc welding is mainly composed of two parts: the welding core and the coating. The welding rod is to apply the coating (coating) uniformly and centripetally on the welding core outside the metal welding core. The composition of the electrode core and the quality of the electrode will directly affect the chemical composition, mechanical properties and physical properties of the weld metal. In addition, the welding rod also has a great influence on the stability of the welding process, the appearance quality of the weld, and the welding productivity. [0003] In the preparation process of the electrode, some additives such as titanate are usually added to improve the welding performance of the electrode, reduce the splash of liquefied metal, and reduce the...
