Tubular wire arc welding
Tubular wire arc welding also uses the arc burning between the continuously fed wire and the workpiece as the heat source for welding. It 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.
When welding, an external protective gas is added, mainly CO2. The flux decomposes or melts when heated, and plays the role of forming slag to protect the molten pool, infiltrating alloys, and stabilizing the arc.
In addition to the above-mentioned advantages of gas metal arc welding, tubular wire arc welding also has more advantages in metallurgy due to the effect of 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
