KHGK Small Caliper Orbital Pipe Welding Equipment

KHGK small caliper orbital pipe welding equipment is designed for full-position automatic welding of pipes with an outer diameter of 16mm to 300mm. Its open-type caliper allows for quick clamping and removal, making installation easy and flexible. This orbital pipe welding equipment also features a digital welding power source that supports constant current and pulsed TIG modes, with a welding current range of 5 to 200A, automatic arc length control, and parameter storage and recall.

Application:

KHGK small caliper orbital pipe welding equipment is widely used in industries such as petrochemicals, power generation, shipbuilding, and construction installation. It is particularly suitable for full-position automatic welding of pipes in prefabrication, large-diameter pipe joints, and space-constrained environments.

Advantages of KHGK small caliper orbital pipe welding equipment:

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.

Applicable industries and scope:

Feature:

1.To addresses the issue of operator error in GTAW . computer-controlled process runs with little intervention from the operator.

2.To guarantee high quality repeatable welding. a successful programming monitors variables and performs periodic samples during its test welding. TIG welding,LCD touch screen, easy to input.

3.Tiny welding head, very convenient to operate in narrow tube installation site.

4.Intelligent welding . 100 successful programming stored in PLC, just pick one.

5.High productivity. 2-3 times higher than conventional TIG welding.

6.Easy operation.Welding heads equipped with fixture device,easy going.

7.Scope of application.Suitable for various kinds of pipe-pipe joint and various groove form

8.10 hours continuous welding. qualified welding head and power and water cooling system make it.

9.Car-integrated design, freedom of movement.

10.Stable welding. Over 20 years development & improvement based on market.

Structure

KHGK small caliper orbital pipe welding equipment 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.
