[0002] Welding wire is a material that plays a key role in the welding process. The following is a detailed introduction to welding wire: Solid welding wire: Solid welding wire is a welding wire made of a single metal material, usually used for welding methods such as metal arc welding and tungsten inert gas welding. There are many types of solid welding wire, which can be divided into carbon steel welding wire, stainless steel welding wire, aluminum alloy welding wire, etc. according to different metal materials. Flux-cored welding wire: Flux-cored welding wire is a welding wire composed of a metal outer skin and an internal flux core. The flux core contains various alloying elements, slag forming agents, arc stabilizers, etc. required for welding. The welding performance of flux-cored welding wire is better than that of solid welding wire. It has the advantages of high welding efficiency, good weld quality, and strong adaptability. Flux-cored welding wire can be divided into basic flux-cored welding wire and acid flux-cored welding wire according to the type of flux core;
