Revolution in welding: Rostec enterprise creates a unique robot for welding in nuclear reactors

Developers say that this is the first welding unit of its kind - there are no analogues in the world

Despite the fact that Russia is not a world leader in machine tool building and the development of various machines for industry, the country creates more interesting devices than primitive locksmith and turning machines. Thus, the Research Technological Institute "Progress", which is part of the Rostec perimeter, has developed a unique CNC machine that can perform high-precision welding even in cramped conditions. For example, inside a nuclear reactor. It is logical that the first sample of the device was sent for testing to Rosatom.

The equipment can perform welding at high currents – up to 500 Amps – and for three hours without interruption. The technological process is fully automated – from regulating the arc voltage for welding to determining the joint of the parts to be joined. These characteristics make the robot irreplaceable for welding work in nuclear reactors.

Interestingly, the thickness of the parts to be welded is not limited. They are connected by argon-arc welding – that is, using an electric arc and an inert monatomic gas. It is assumed that the robot will be checked remotely – using a camera. An infrared pyrometer is also provided for determining the temperature of the product being welded.
