Advances in Welding and Joining Technologies

About the course:
The progress of several welding and joining processes is ever increasing with the development of new materials and their application in modern technologies. The microjoining and nanojoining is even more challenging area with the development of miniature components. This course is primarily designed from fundamental understanding to the most recent advances in welding and joining technologies. The syllabus is oriented to the advancement of the joining technologies which is different from conventional welding and joining processes. The modules cover almost all the direction of joining technologies and it is blended with fundamental development to the recent technologies. Audience will be able to develop fundamental understanding on different perspective and recent development in this field through the lectures and reinforce their knowledge by solving assignments. This course is presented in a lucid and simplified way to make it enjoyable to the beginners.

About the Instructor:




Prof. Swarup Bag

The broad area of instructor’s teaching and research interest is materials and manufacturing processes through computational models and experiments. The instructor completed his Ph.D on “Development of bi-directional heat transfer and fluid flow model for reliable design of GTA and laser welding processes” from Indian Institute of Technology Bombay. Later he has worked at the Center for Material Forming (CEMEF), MINES Paris Tech, France in Metallurgy, Structure and Rheology (MSR) group. Soon after post-doctoral research experience, he joined in the Department of Mechanical Engineering, Indian Institute of Technology Guwahati as a faculty member. His primary area of research is fundamental process modeling of welding and joining technologies, optimization of manufacturing processes and recrystallization in metal forming processes. Dr. Bag has published about 43 journal papers, 38 Conference papers, and 8 book chapters related to welding and joining processes. He is the author of the book ‘Computational models for GTA and laser welding processes’ and recipient of ‘Royal Arc Award 2009’ from Indian Institute of Welding for the best PhD thesis in welding. The instructor is involved in teaching the subjects like ‘Physics of Manufacturing Processes’, ‘Engineering Materials’, ‘Mechanical Behavior of Materials’ and ‘Manufacturing Technology’ at IIT Guwahati. The subjects broadly covers the mechanical metallurgy, theory of plasticity, heat transfer in welding and machining processes, crystallography, dislocation mechanism, phase diagram and phase transformation and solidification.
