Mechanical Engineering
Research and development in the area of laser material processing, including welding of dissilar materials such as steel with titanium, surface hardening, remelting, alloying, cladding with metal ceramic composites, metal forming, water-jet assisted underwater cutting and additive manufacturing to develop a better understanding for process control and widen the scope of their applications. Development of engineering solutions employing these processes, such as functionally graded laser depositions for joining dissimilar metals , refurbishing parts, and fabricating friction stir welding tools for high temperature applications. Emphasis on the online process monitoring of laser processing and correlating the thermal history with the microstructures evolved and the mechanical properties. Understanding the mechanical behaviour of laser selective melted parts under dynamic loading conditions.
