Manufacturing Process I

Manufacturing Process I. Instructors: Prof. Inderdeep Singh, Dr. D. B. Karunakar, and Prof. D. K. Dwivedi, Department of Mechanical and Industrial Engineering, IIT Roorkee. The first part of this course taught by Prof. Inderdeep Singh begins with topics in powder metallurgy, and then deals with topics in sheet metal forming operations and machining processes. The second part of the course taught by Dr. D. B. Karunakar discusses topics in metal casting such as patterns, casting processes, melting furnaces and practice, and casting defects. The third and last part taught by Prof. D. K. Dwivedi covers topics in welding including shielded metal arc welding, submerged arc welding, gas metal arc welding, and tungsten inert gas welding.
