KH series orbital welding machine, with open and closed welding heads, it can automatic welding pipe to pipe, tube to tube, tube to tubesheet, etc. It adopts advanced inverter power supply, self-designed control system and accordingly control software.

The closed-head orbital welding machine adopts advanced pulsed TIG (argon arc) welding technology to achieve precise, high-quality welding of enclosed pipes and fittings. With intelligent control of heat input and arc stability, it minimizes material deformation while ensuring smooth, uniform welds. The closed welding head provides excellent gas protection, preventing oxidation and guaranteeing clean, aesthetic seams. Designed for high efficiency and repeatability, this closed-head orbital welding machine is ideal for fully automated pipe welding operations that demand accuracy and consistency.

This closed head orbital welding uses a modular sealed welding head to achieve zero-defect welding in an inert gas protection environment. It supports pipe diameters of 10-200mm, welding thickness of 0.5-8mm, and uniform inner wall molding without oxidation. In addition, the weld seam Ra of this closed head orbital welding is ≤0.4μm, which meets the 3A hygiene standard. An optional remote monitoring module can be used to record the welding data chain in real time.

This pipe welding machine utilizes pulse argon arc welding technology, ensuring precise and efficient welding of closed pipes. The automated pulse function allows for controlled heat input, reducing distortion and ensuring excellent weld quality.
