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).

KHGC series enclosed type orbital weld head can be used for tube outer diameter from Ф3-Ф180mm tube to tube automatic welding at all positions. It is suitable for welding carbon steel, alloy steel, stainless steel, and titanium alloy thin-walled tubes. In addition, this orbital weld head uses a maxon servo motor that is suitable for small spaces. The welding head can rotate continuously without the need for spot welding.

KHGC closed head orbital tube welding machine is a specialized auto arc welding machine whereby the arc is rotated mechanically through 360° around a static work piece of tube to tube with tube specification φ3～φ114 mm and tube thickness 0.8～3mm.Its enclosed welding head fully protects the weld pool, minimizing oxidation and ensuring superior weld quality. This orbital tube welding machine features six welding heads to accommodate various tube sizes.

KH-315A 3-in-1 orbital automatic welding machine is equipped with both open and closed orbital welding head, enabling automatic welding of tube-to-tube, tube-to-tube, and tube-to-tubeplate. It utilizes an advanced inverter power supply, a proprietary control system, and corresponding control software. KH-315A orbital automatic welding machine is a 3-in-1 multifunctional machine suitable for 11 different types of orbital welding heads, including the KHGK, KHGC, and KHB12-80 series.

This khgk open-head orbital welding equipment for sale is designed for large-diameter and thick-walled pipes, as well as complex weld structures. Its open-head welding head allows for flexible operation in confined or irregular working conditions, supporting high-precision welding of a wide range of materials. KHGK open-head orbital welding equipment utilizes advanced arc control and constant heat input technology to ensure uniform weld formation and consistent quality. Its lightweight design facilitates installation and maintenance, while also offering excellent compatibility with a variety of power supply systems.

The KHGK Caliper-type orbital mig welding machine is designed for full-position automatic welding of pipes with an outer diameter of 16 to 300 mm. Developed independently by our company, the entire machine utilizes an advanced inverter DC pulsed TIG welding power source and a PLC module control system. This orbital MIG welding machine features a caliper-type structure, enabling rapid clamping and stable positioning of pipes, adapting to varying pipe diameters and complex working conditions.

This welding track carriage is an efficient, intelligent automated welding device designed specifically for curved circumferential welding. Mounted on a dedicated welding track, the welding carriage ensures the welding gun moves smoothly along a predetermined path, achieving uniform, continuous, and high-quality welds. Equipped with a variable speed drive system, the welding track carriage allows operators to flexibly adjust the travel speed to suit different materials, thicknesses, and welding processes.

This welding carriage has a built-in precise control system and supports multiple welding modes, such as straight welding and curved welding. Its powerful magnetic device can be firmly attached to any metal surface and is suitable for horizontal, vertical, inclined and curved surfaces. One person can operate multiple magnetic welding carriages at the same time, greatly reducing labor costs.

KHB12-80 Tube Sheet welding machine is a specialized auto arc welding machine whereby the arc is rotated mechanically through 360° around a static work piece of tube to tube sheet with tube specification φ12～φ80 mm.
