Welding Metallurgy

By Prof. Pradeep Kumar Jha   |   IIT Roorkee
Learners enrolled: 185
The course focuses on understanding the metallurgy and solidification of weldments The course will make the students aware with the metallurgical aspects of welding. For getting a sound weld, the students are required to be aware of the science behind the welding phenomena, especially in the domain of weld metal solidification, heat transfer, heat treatment processes, strengthening mechanisms etc. The course will be useful for engineering graduates as well as professionals working in the area of welding.
