Mature technology and advanced technology

23 years of experience in intelligent welding equipment technology R & D and manufacturing, multi-generation product process accumulation and upgrade,compact machine head and small in size, adopts elastic positioning mandrel and three-point support frame, which can be adjusted circumferentially, axially and radially, and the operation is fast. accuracy in positioning.

Imported motor, stable and reliable

The IGBT inverter is used to control the DC pulse current, the welding efficiency is high, the arc stability is strong, and the bead is beautifully formed.

Operating economy, efficient production

The TIG water-cooled welding torch is equipped with a 16-liter stainless steel water tank, which is not limited by the on-site water pressure and other conditions. The cooling is sufficient to ensure that the welding machine can work 24 hours a day.

Easy to operate

The program control system is easy to operate and can store up to 100 welding specifications. Each group can be divided into 1 to 16 segments. It can be operated with simple training without special foundation and special language. The truck-mounted integrated design is free to move and easy to use.



KHB 12-80 Tube Sheet 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 sheet with tube specification φ12～φ80 mm. 

KHB 12-80 could address the issue of operator error in gas tungsten arc welding(GTAW). 

KHB 12-80 is composed of the power supply with integrated computer control and the welding head.  

KHB 12-80 could process carbon steel, alloy steel, stainless steel and titanium alloy. 

KHB 12-80 Mainly used in chemical industry, boilers, heat ex-changers, pressure vessels and other industries.   .
 
KHB 12-80 could be used for 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. 




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. LCD touch screen, easy to input.

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

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

5.Easy operation. Equipped with the elastic positioning mandrel, three-point support frame, accurate positioning.

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

7.Car-integrated design, freedom of movement.

8.Small space of scientific design
