flux cored wire

Rolled into a round or shaped steel tube with a thin strip of steel, filled with a certain amount of powdered medicine, made by pulling a cored wire, or a seamless flux cored wire made by filling the tube with a powder (see figure). With this kind of welding wire, the welding efficiency is high, the adaptability to steel products is good, and the trial production period is short, so its usage and use range are continuously expanding. This welding wire is mainly used for carbon dioxide gas shielded welding, submerged arc welding and electroslag welding. The powder composition in the flux cored wire is generally similar to that of the electrode coating. The flux-cored wire containing slagging, gas generation and arc-stabilizing components does not require shielding gas during welding. It is called self-shielded flux-cored welding wire and is suitable for the construction of large-scale welded structural projects.
