Application Principle: The welding wire acts as an electrode, and the arc burning between the continuously fed welding wire and the workpiece serves as the heat source to melt the welding wire and base metal. During welding, shielding gas (such as Ar + 1~3% O?) is continuously delivered to the welding zone through the welding gun nozzle, protecting the arc, molten pool and adjacent base metal from harmful air. The welding wire melts continuously and transfers into the molten pool in droplet form, fuses with the molten base metal and solidifies to form a weld seam.
