CSIR perfects laser welding

May 2010 News

Researchers at the Council for Scientific and Industrial Research have demonstrated a world-first laser cladding system that offers a permanent solution to sealing leaks and repairing cracks at power stations.

The laser beam welding technology, which was developed for Eskom in collaboration with Eskom welding engineers, will aid in the maintenance of South Africa’s power stations, particularly in the sealing and repair of leaking water coolers in situ – without having to drain the coolers before conducting the repair work. The state-of-the-art system is mobile and able to reach multistorey heights with the laser power unit located on the ground from where the system is controlled remotely by an operator.

The technology breakthrough coincides with the 50th anniversary of the laser.
