Tip：Tubular wire arc welding method
Tubular wire arc welding also uses the arc burning between the continuously fed welding wire and the workpiece as a heat source for welding, and can be considered a type of gas metal arc welding. The welding wire used is a tubular welding wire, and the tube is filled with flux of various components.
During welding, a shielding gas is added, mainly CO2. The flux decomposes or melts under heat, and plays the role of slag protection, alloy infiltration and arc stabilization.
In addition to the advantages of gas metal arc welding mentioned above, tubular wire arc welding has more advantages in metallurgy due to the effect of the flux in the tube. Tubular wire arc welding can be applied to the welding of various joints of most ferrous metals. Tubular wire arc welding has been widely used in some industrially advanced countries. "Tubular welding wire" is what is now called "flux-cored welding wire".
