Product Description
The orbital weld head MWG series, which are impressive with a wide range of applications, are used where thin-walled stainless steel tubes are welded in tube installation. Due to the compact design and the equipped narrow weld head hosing, it is possible to weld even under narrow conditions.
The MWG 230 open head orbital welding machine with a welding range of 130-230 mm is applicable for tubes with a wall thickness of 2 -10 mm and applicable for V-shaped beveling. It can be used for tube installation in fields of pressure vessels, boilers, petrochemical engineering, etc.
Open Orbital Weld Head
This type of open orbital weld head allows you to make very high-quality welds in minimal space. There is a mechanical tracking system to keep a constant arc height. The torch can tilt to weld at an angle. This type of machine can be used to weld carbon steel and stainless steel tubes. The open head offers very wide welding possibilities thanks to the inclination of the torch and the addition of filler metal. The clamping range is achieved without the addition of jaws. All the parts in contact with the tube are made of stainless steel so as not to contaminate it.


Integrated Control Power Supply MWA-400
It is user-friendly to users, even the beginners. Only after a short period of learning, they can easily generate programs. Of course, the advanced functions are also available to advanced users who are looking to customize their programs. The facilitated access to parts makes our power sources robust and easy to maintain. The combination of an easy-to-use and sturdy package allows you to be competitive and makes this range the best choice for all your current or future projects.



* The equipment adopts a standard modular design, the replacement of spare parts is convenient.
* The rotation of the welding torch is more accurate and stable, and the angle of the welding seam is monitored in real-time, due to the speed measurement function with feedback.
* With automatic arc length and yaw function, it can meet the welding of pipe fittings of different sizes.
* The welding torch is cooled by circulating water, with a high-duty cycle. And it can work stably and reliably for a long time.
* Under the same condition, different pipe diameters can be welded without readjusting the welding parameters.
* The welding torch adopts the Haval fixture, which can be adjusted according to the diameter of the pipe fittings,so that the welding torch can firmly lock the pipe fittings.
