KHGC Closed Head Orbital Tube Welding Machine

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.

Application:

The KHGC closed-head orbital tube welding machine is widely used in industries such as pharmaceutical, food and beverage, semiconductor, and aerospace. It provides contamination-free, repeatable welds for pipelines, process systems, and critical fluid transport applications.

Advantage

Advantages of orbital tube welding machine:

1. Double clamping positioning, good positioning effect, no need to locate spot welding, improve welding efficiency.

2. Pulse power supply, closed design of the welding head, good protection effect, uniform and beautiful weld seam.

3. Lightweight structure design, suitable for assembly site with small space.

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

5.Beautiful welding beam with excellent seal performance. TIG welding, no feeding wire and closed welding space by welding head, together makes high seal performance without new impurity, so its welding beam looks beautiful.

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

7.To guarantee high quality repeatable welding. a successful programming monitors variables and performs periodic samples during its test welding. LCD touch screen, easy to input.
Intelligent welding . 100 successful programming stored in PLC, just pick one.

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

9.Easy operation. Clamp device to fix the two separated tubes tightly, no need for spot welding, precise positioning.

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

11.Portable, freedom of movement.

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

Structure

a) After completing the welding program setting on the control box panel, place the tube on the positioning cover, close the positioning cover, tighten the rotating sleeve, press the start button on the remote control, start to deliver air in advance, and fill the head cavity with argon.

b) After the gas forms a stable argon gas protection environment, the welder starts to arc, and the current gradually rises from the arcing current to the welding current. At this time, the welding moment does not rotate, and the purpose is to preheat the pipe, and the process can be input through.

c) The rise time parameter is used to control. When a stable molten pool is formed on the workpiece, the torch begins to rotate. During the rotation process, there will be flat welding, downslope welding, overhead welding, upslope welding at some time.

d) This welding machine allows the user to set any segmentation of 1~6 segments within 360° according to the situation, and set them separately. Each section of welding speed, current magnitude and other parameters make the weld as a whole consistent. When the welding torch rtates o365° (the lap angle can be set arbitrarily, the welder enters the attenuation program. At this time, the machine head continues to rotate, and the current gradually decreases from the welding current to the arcing current, forming a weld joint.

e) It can be controlled by entering the fall time parameter. The welding process of the entire nozzle is automatically completed according to the setting procedure after the start button is pressed.
