New laser-based technology for autonomous repair of high value components in defence

An Indian scientist has developed technology that autonomously repairs and restores high-value components such as moulds, turbine blades and other aerospace components with minimal human intervention.

The technology has immense scope in defence and aviation sectors.

Repair techniques being used at present like welding and thermal spraying are ad hoc and do not provide the desired level of accuracy and precision.

Moreover, they are manual and the quality of work depends upon the skill of the technician.

The technology, developed by Prof Ramesh Kumar Singh, from the Indian Institute of Technology, Bombay, uses a laser for a high level of process control and is totally autonomous, which ensures repair or restoration with better quality and repeatability.
