Flux-cored welding wire is a promising new type of welding material. In recent years, the types and dosages of domestic flux-cored welding wire have been increasing. Compared with solid wire, flux-cored wire has the following advantages and disadvantages.
1) The welding wire manufacturing process is complicated
2) When welding, it is difficult to feed wire with solid wire
3) The wire surface is easily rusted and the powder absorbs moisture. Therefore, the management of the flux cored wire is more strict.
