KHGK Open Head series Orbital Welders Tube to Pipe Automatic Pulse Argon Arc Welding Machine
Warm Prompt: Different Model has different price.
When you inquiry, we quote for you.
KHGK could do auto welding of tube to tube, tube to flange, tube to elbow and tube to tee.
KHGK Open heads have OSC/AVC functions - with oscillation OSC and arc voltage control AVC.
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.
Pipe joints beveling requirement:
Applicable industries and scope:
Features:
1. To addresses the issue of operator error in GTAW/TIG . computer-controlled process runs with little
intervention from the operator.
2. We use Famous Panasonic brand welding source rather than Chinese brand.
3. 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.
4. Weld heads have OSC/AVC functions - with oscillation OSC and arc voltage control AVC, to ensure the arc length is kept at a constant and stable welding.
5. Tiny welding head, very convenient to operate in narrow tube installation site.
6. Intelligent welding . 100 groups welding programs are stored in PLC system, just pick one.
7. High productivity. 2-3 times higher than conventional TIG welding.
8. Easy operation.Welding heads equipped with fixture device,easy going.
9. Scope of application.Suitable for various kinds of pipe-pipe joint and various groove form
10. 24 hours continuous welding. qualified welding head and power and water cooling system make it.
11. Trolley-integrated design with wheels, freedom of movement.
12. Stable welding. Over 28 years development & improvement based on market.
13. Suits for beveling type of V, Y, J/U, and others compound beveling shape, pipe joint beveling angle 0 - 90°
Technical Specifications:
Total 5 models of welding heads, the dimension sizes of welding heads as below:
Weld heads:
1. Can be used with and without cold wire attachment, as the cold wire feed nozzle; can be adjusted exactly in both a vertical and horizontal direction via an adjustment unit.
2. Weld heads have OSC/AVC functions - with oscillation OSC and arc voltage control AVC. The arc length is kept at a constant gap mechanically.
3. The water-cooled TIG Torch head can be swiveled in any direction and allows fillet welds or short hollowed out tubes to be welded. TIG Torch head is secured to a slide unit that allows the position of the electrodes to be finely adjusted with great accuracy even during welding.
4. Smaller built-in wire feeder on weld heads(excludes KHGK16-40 & KHGK36-90 model), can supply for wire 1kg/2kg.
5. Bigger separate external wire feeder, can supply for wire 15kg at least.
6. With a simple to operate control knob, it is possible to adjust the clamping area across the welding head's entire nominal range.
7. The weld heads with removable clamping shells made from tool steel ensures optimum retention to the tube's surface (very good grip properties).
8. The welding heads are easily centered to the tube and are clamped in place with the help of a tension lever. No additional remote control is required thanks to the keys integrated directly into the welding head housing.
Removable inner clamping shells set:
1. Each set of clamping shells includes 2 pcs. And each size of clamping shells suit for one pipe size.
2. Quick removable inner clamping shells.
