Automatic Tube to Tube Sheet Orbital Welder for Heat Exchanger and Boiler

Product Description

. . Product Description KHB12-80 Tube - Tube Sheet Orbital Welder
KHB12-80 could address the issue of operator error in gas tungsten arc welding(GTAW/TIG).
KHB12-80 is composed of the power supply with integrated computer control and the welding
head.
KHB12-80 could process carbon steel, alloy steel, stainless steel, titanium and other alloy.
KHB12-80 Mainly used in boilers, heat ex-changers, pressure vessels, chemical industry and
other industries.
KHB12-80 could be used for Tube-tube sheet joint forms as following pictures showing:
flat head butting (fusion welding), external extension angle joint (external angle welding),
indent angle joint (internal angle welding) and so on, with or without wire feeding.
Features:
1. To addresses the issue of operator error in GTAW / TIG . PLC-controlled process runs with little
intervention from the operator.
2. Famous Panasonic brand welding source & Switzerland Maxon motor rather than Chinese brand.
3. 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.
4. Intelligent welding . 100 groups of successful programming stored in PLC, just pick one.
5 High productivity. 2-3 times higher than conventional TIG welding.
6. Easy operation. Equipped with the elastic positioning mandrel, three-point support frame, accurate
positioning.
7. 24 hours continuous welding. qualified welding head and power and water cooling system make it.
8. Car-integrated design, freedom of movement.
9. Small space of scientific design.
Weld heads
1. Tube to tube sheet orbital weld head.
2. Narrow design and Portable type with less weight only 6.5kg. And There is a spring balancer which can handle the weld head.
3. Can automatic return back after finishing welding work.
4. Water cooling channels running through the entire weld heads body have provided for excellent heat dissipation that enable the weld heads to work continuously for long time even at high welding currents and intensive load.
5. The enclosed design and the insert gas management system of the heads ensure a permanent infiltration of the weld seam during welding work.
6. Insert wire feeder system.
Different sizes of Mandrels & Elastic positioning tools:
1. Mandrels is normal size, can supply for kinds of Elastic centering tools
2. Each set of Elastic centering tools includes 2 pcs. And each size of Elastic centering tools suit for one pipe size.
3. Quick removable centering tools.
Remote Control Box:
1. Humanized designing and layout, easy operation
2. Shortcut buttons with English language labels
3. 5m cables(can be customized)
4. Can adjust the welding parameters during welding work
