Finite Element Modeling of Weld Deposition Based Additive Manufacturing.
Masters thesis, Indian Institute of Technology Hyderabad.
Abstract
Additive Manufacturing (AM) is an early design exploration and validation process, in which executable models of a system are created that reflect some subset of properties of interest. It is a process that automatically creates a physical prototype from a three dimensional computer aided design (CAD) model, in a short period of time. It is an indispensable tool for shortening product design and development time cycles. Amongst these, the methods to create metallic prototypes are of special interest
to the industrial community and thus research on employing direct metal deposition for the fabrication of fully functional parts and tooling has generated significant interest in recent years. Amongst the deposition based methods using laser, electron beam, arc as the energy source, arc based methods like weld-deposition using Gas Metal Arc Welding (GMAW) are quite suitable for applications requiring high deposition rates.
