Additive Manufacturing

Wire and Arc Additive manufacturing (WAAM) technology is a wire-based direct energy deposition (DED) technique which utilizes an electric arc for melting feedstock material. WAAM technology consists of complex physical phenomena during the deposition of material like heat transfer, metallurgical transformations, and non-equilibrium solidification. Multi-layer deposition of material causes repeated thermal cycles which in turn affects the microstructural and mechanical properties. Our current research interest focuses on the numerical modelling of various WAAM processes.

Current Interest:

1. Development of novel Induction based WAAM process.

2. Development of FE-based numerical model for thermal, mechanical, and metallurgical analysis of the additively manufactured component.

3. Development of FE-based numerical model for additive manufacturing of FGMs.
