Flux-cored wire, also called powder-cored wire, tubular wire, it is divided into two categories of gas protection and no gas protection. The surface of flux-cored wire is made of low carbon steel or low alloy steel. The manufacturing method is that the steel strip is first rolled into a U-shaped section shape, then the welding powder is added to the U-shaped steel strip according to the dosage, then pressed down by a press mill, and finally, the flux-cored wire of different specifications is made by drawing.Flux-cored wire, also called powder-cored wire, tubular wire, it is divided into two categories of gas protection and no gas protection.
