Description

technical field [0001] The invention relates to the technical field of thermal spraying, in particular to an Fe-Si-Mn-W welding layer material and a preparation method thereof. Background technique [0002] The visible light (arc light) during welding is called open arc welding, such as electrode arc welding, argon arc welding, and secondary welding. Submerged arc welding is performed under flux, not arc welding. The application of open arc welding and submerged arc welding has great potential. Its application characteristics can be summarized as the following four points: 1. The combination of surface engineering and a variety of composite materials has obvious advantages in material design; 2. The chemical composition of materials can be easily adjusted; 3. It can be dynamically formed with special structural properties 4. The combination of multiple materials and multiple technologies can obtain excellent performance. [0003] However, the development of submerged arc ...
