This orbital tube welding machines adopts a high-precision servo control system to achieve 360° full-position automatic welding. Suitable for a variety of materials such as carbon steel and stainless steel, the welding speed is adjustable (50-300mm/min), and the repeat positioning accuracy is ±0.05mm, ensuring that the weld is uniform and defect-free. This orbital tube welding machines is equipped with an intelligent parameter memory function and a gas protection system, supports pulse welding technology, and significantly improves the welding qualification rate of thin-walled tubes (starting from 3mm).
