KHGT Pipe To Pipe Butt Welding Machine

The KHGT pipe-to-pipe butt welding machine is designed for high-precision butt welding of pipes with diameters ranging from 19–80 mm. It is suitable for materials such as carbon steel, stainless steel, and alloy steel. The machine consists of a welding power source, control system, cooling system, wire feed mechanism, and welding head workstation. It features oscillation current control (OSC) and arc voltage control (AVC) functions, effectively eliminating manual operation errors. It utilizes a PLC intelligent control system and a touchscreen human-machine interface, and can store up to 100 welding programs, enabling fully automated intelligent welding.

Application:

The KHGT pipe-to-pipe butt welding machine is widely used for pipe prefabrication and assembly welding in high-purity welding applications such as the food, pharmaceutical, semiconductor, energy, and precision manufacturing industries.

Advantage

Advantages of the Kehui pipe-to-pipe butt welding machine:

1.High-precision control: Built-in OSC (oscillation control) and AVC (arc voltage control) systems enable automatic weld tracking and uniform weld penetration.

2.Fully automatic operation: PLC control and a touchscreen interface store 100 welding programs for ease of use.

3.Forced water cooling system: A 16L stainless steel cooling water tank ensures continuous welding for extended periods, unaffected by external water pressure.

4.Lightweight structure: Key welding head components are constructed of aviation-grade materials, ensuring low weight and high-temperature resistance.

5.Reliable drive: A stepper motor precisely controls wire feeding and drive, adapting to a variety of groove and pipe connection methods.
