Linear friction welding

Linear friction welding is a pressure welding process. It follows the same principles as rotational friction welding. The difference: with this technology, the accelerated component oscillates with linear movements. This process is used primarily in the aerospace industry. 

Linear friction welding: the technology

In linear friction welding, one of the components to be joined is firmly clamped. The other component is accelerated with a linear movement. Then the two parts are pressed together with high pressure. This creates friction heat.

The two individual materials can thus be joined together. The resulting weld flash is trimmed off at the end.

Linear friction welding has proven successful particularly in the aviation industry. This is where integral rotors are made: so-called blisks

Automated friction welding

Automated linear friction welding is used primarily in the aerospace industry. But this process is becoming more popular even in medical technology and the automotive industry.

As a KUKA customer you get more than just high-quality machines and safe control software: you also benefit from many years of technical expertise.

Linear friction welding: the advantages

Unlike rotational friction welding, linear friction welding results in friction over the entire welding area. This means that

  • short welding times are achieved regardless of the size of the component,
  • difficult-to-process materials, such as titanium or nickel-based alloys and
  • asymmetrical components, can be joined easily.
