This welding head is a special welding head specially designed for tube/pipe TIG welding, suitable for automatic welding of tube/pipe in the form of narrow spacing. It can weld various pipes/pipes such as carbon steel and stainless steel. The diameter of the tube ranges fromΦ32 to Φ51mm, and two methods of wire filling or self-melting can be selected. The arc length and yaw function can be adjusted automatically. It can precisely realize all-position TIG tube/tube welding, with high reproducibility of welding results and ideal welding results. Mainly used in chemical, food, boiler, military and nuclear power industries.
