Analysis and Modeling of Welding

ABOUT THE COURSE

Welding is an important fabrication process in manufacturing industries. Complex parts fabricated using forming, machining and metal removal processes are assembled into a larger part using welding. The welding process involves a number of physical processes that play a role in determining the performance of the joint. With newer and dissimilar combinations required to be joined as the technological advances take place in the area of manufacturing, it is important for practicing engineers, graduate students and prospective researchers to understand welding to take advantage of the developments taking place. This course offers detailed analysis and modeling techniques that apply to the different physical phenomena that take place during welding.

INTENDED AUDIENCE

Students who have completed undergraduate studies in Engineering or Science will be in a better position to benefit from this course.
