[0002] Welding wire is also called powder core welding wire and tubular welding wire, which is made of low-carbon steel or low-alloy steel with good plasticity. The manufacturing method is to first roll the steel strip into a U-shaped cross-section, then fill the welding powder prepared according to the dosage into the U-shaped steel strip, and roll it tightly with a press roller. Finally, different specifications of welding wires are made by drawing.
