Finite Element Modeling of Welding Processes

This learning track covers a comprehensive understanding of various welding processes, techniques, and their applications. It begins with the fundamentals of finite element modelling of welding processes, exploring the different components, classifications, and the physics behind these processes. The track then delves into the basics of different welding processes, their properties, and the manufacturing processes involved. It also discusses the key physical and mechanical properties of materials, the importance of understanding these properties in developing numerical models, and the challenges in multi-scale modelling. The track concludes with an overview of data-driven modelling approaches, solid-state welding processes, including brazing and soldering, and the principles of diffusion welding, ultrasonic welding, explosive bonding, and electromagnetic pulse welding. The track also covers the advanced welding processes, including laser beam welding, electron beam welding, and micro welding. It provides a comprehensive understanding of the advantages, disadvantages, and factors influencing these processes, along with their applications in various industries. For instance, the track delves into the concept of wire additive manufacturing processes associated with laser beam welding, explaining the conduction mode and keyhole mode in laser welding. It also discusses the role of power density and its impact on the welding process. The track further explores the advancements in laser micro welding processes and their applications in the medical field, particularly in the manufacturing of medical devices. Additionally, it introduces the Finite Element Method (FEM) in modeling different aspects of fusion welding processes and the concept of elastic stress analysis.
