Laser Tech To Repair Components
Scientists at IIT Bombay have devised a new laser technology for the repair and restoration of high-value components such as molds, turbine blades, and other aerospace components that require minimal human intervention. The existing repair techniques like welding and thermal spraying are ad hoc and do not provide accuracy and precision. Moreover, all the existing technologies are manual, and the quality of repair depends upon the skill set of the person. The novel technology uses a laser for excellent process control and is completely autonomous with minimal to zero human intervention. This ensures restoration with enhanced quality and repeatability. The defective component which requires repair will be scanned autonomously for damage detection via a laser scanner, and the deposition path will be determined based on certain algorithms. The laser-directed energy deposition (LDED) technique will be used to deposit the material, followed by finishing and automated inspection of the restored product.
