Circular welding machines KMO are specifi cally designed for welding the bottoms and tubes of containers. We have engineered a hydraulic clamping device that ensures precise and secure clamping of both the tube (cylinder) and the bottom. The clamping is done from the inside of the tube which ensures that it is round and also includes protection gas fl ow. That allows for automatic welding without the need for prior tack binding welds. The inner device is equipped with a built-in argon fan to protect the root of the weld.

The machine can be opened at its end for the insertion of tubes. The tube is supported on two sides. At the back there are bearing supports that can each be manually extended to fi t the required diameter. The bearings can also be moved longitudinally (motorized) depending on the tube length. The front support is the aforementioned hydraulic clamping device with copper rail, which can be replaced as needed based on the diameter of the tube.
