KHGK Tube-Tube Automatic Welding Machine(Open Head Orbital Welder)
KHGK Tube-Tube Automatic Welding Machine(Open Head Orbital Welder) 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 φ16~φ300 mm and thickness 15~20mm..

Application:

KHGK orbital welder is widely adopted in the installation of plants such as water /oil/gas plant, food& alcohol plant,chemical industry, medicine and other industries.

Parameter:

Wire feed speed adjustment: 0.1-1.5m/min;
insert memory: 100 welding manner;
Pipe diameter: φ16 mm ~φ300 mm.
Advantage
KHGK Open Head Tube Orbital Welder is 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 φ16~φ300 mm and thickness 15~20mm..

KHGK could address the issue of operator error in gas tungsten arc welding(GTAW).

KHGK is composed of the power supply,control system,cooling system and the welding head. 

KHGK could process carbon steel, alloy steel, stainless steel and titanium alloy.

KHGK could do auto welding of tube to tube, tube to flange, tube to elbow and tube to tee.

KHGK is designed with tiny welding head, very convenient to operate in narrow tube installation site. Meanwhile, its TIG welding makes high seal performance.
 
Therefore, KHGK orbital welder is widely adopted in the installation of plants such as water /oil/gas plant, food& alcohol plant,chemical industry, medicine and other industries.

Structure

KHGK series consists of power, control system, cooling system, remote control and welding head, and etc;
Separated design for the equipment, makes it not only convenient to operation and management, but also facilitate for production workshop or production site to move freely and easily.

The KHGK series of equipment is divided into five models, which are suitable for different pipe diameters. According to the user's pipe diameter and the space condition, different types of equipment can be selected. The control system of the equipment is compatible from large to small. It is convenient for users to purchase a set of control systems in small batch production. When equipped with other welding heads, it saves costs.
