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-Tube Welding Machine is a specialized automatic orbital tube welding machine, It can automatic welding 360 degrees around the tube, There are 6 welding heads at the same time, which can adapt to the welding of different sizes of tubes.

KH auto pulse argon arc orbital welder can realize auto welding of KHGK Caliper tube - tube, KHGC closed tube-tube and KHB12-80 suspension tube plate. It adopts advanced inverter power supply, self-designed control system and accordingly control software.

The KHPP Magnetic Type Orbital Pipe Welding Machine is a customized machine, which is used for fabricated tube orbital welding projects - the pipe is fixed, welding carriage do all-position welding around the tube with the efficiency-cost MIG welding process. Suiting for large sizes tube Diameter≥140mm (≥5 inch), thickness 4 - 60mm.

This large orbital pipe automatic welding machine enables high-precision welding operations with the help of advanced sensors and control systems. The welding position, welding angle and welding seam quality can all meet national standards.

This trackless welding carriage is an intelligent welding device that does not require additional track installation, which enables flexible movement and efficient welding. This trackless welding carriage is equipped with a high-quality wheeled chassis and can travel freely on flat or slightly irregular metal surfaces. The equipment has a built-in intelligent navigation system and precise path control, supporting straight, curved and multi-angle welding.

The open weld head is designed as a tool for filler wire orbital TIG welding. This series of welding heads has AVC/OSC functions and is commonly used for thick-wall (1.5mm - 20mm) pipe-to-pipe/elbow/flange welding. The full range of welding heads covers the pipe outer diameter range from 16mm to 324mm. Tube-to-tube welds are a form of caliper design,pipes can be easily clamped and easily adjusted to accommodate pipes of different diameters.

KHGK series pipe-to-pipe fully automatic pulse argon arc welding machine is specially designed for all-position automatic welding of pipes with an outer diameter of 16 to 300mm. The entire set of equipment is independently developed by our company. It adopts advanced inverter DC pulse argon arc welding power supply, vehicle-mounted integrated design, touch screen data input, and PLC module control system.

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.
