Description
Welding is the permanent joining process that is used to produce weldments between two similar and dissimilar materials with or without the application of heat or pressure. This course focuses on the theoretical aspects of various welding processes in a detailed manner. Welding processes such as arc welding, laser beam welding, atomic hydrogen welding, resistance welding, projection welding, etc. Learners who like to enroll in this course should be familiar with some basics of mechanical engineering and material science domain.
