Learn about the physics of welding processes. The course is divided in seven parts. It will cover the entire spectrum of welding processes that are commonly used for engineering applications. It begins with a general survey and classification of welding processes based on various methodologies with discussions on heat source and the principles behind heat generation. There will be discussions on the most widely used arc welding process and the physics behind Arc. What is arc and how is heat generated in Arc? What are the reactions in an arc? The course will further move to discuss the processes such as gas tungsten arc welding, the physics and the application of such a process and parameters that would affect the stability of these process. The course will proceed with discussions about consumable welding processes with its focus on Gas Metal Arc Welding and the variants of this process. Learners will also see how the process characteristics change the metal transfer characteristics and its behaviour. The course will talk about Laser and Electron Beam Welding and end with solid state welding processes such as friction welding, ultrasonic welding and explosive welding, which does not involve melting     Read more
