This course focuses on understanding the metallurgical principles and concepts of welding processes. Students are required to be aware of the science and engineering behind welding phenomena especially in the domain of weld metal solidification, heat transfer, heat treatment processes, strengthening mechanisms, formation of heat affected zones etc. The course will be useful for engineering graduates as well as professionals working in the area of welding.

The course requires an introductory knowledge of basic manufacturing processes, material science and engineering. It broadly includes the following topics such as introduction to welding metallurgy, phase diagrams, phase transformation, heat treatment processes, metal strengthening approaches, heat flow and pressure distribution in welding, concept of solidification and heat affected zones in welding, residual stresses and distortion and solidification cracking.

  • I learned a lot. Very knowledgeable Course. I am preparing for CSWIP 3.1 Exams and I am confident to pass after learning this course
  • It is very informative and nice course. With the help of this course one should understand the meaning of welding Matellurgy.
  • Corey Leblanc
    This is a awesome course to take it helped me learn and have a better understanding about metal and welding how it combined to Form one complete work piece.i recommend this class to anyone who is interested in learning how to weld.
  • Motsoeneng Molohadi Precious
    One of the best and easiest courses I have ever enrolled for. The lecturer throughly explains everything so that it is easy to follow and learn.
  • Princely Chukwuemeka J. Akanegbu
    Thanks so so very much Prof K. Jho for the inside knowledge of welding metallurgy, this will help me allot. During my inspection process and documentation

    This course is a good course to take provided that you can remain self-motivated throughout the semester. There are various ways to learn the material, and freedom to work when you have time and not in a highly structured environment. The longer assignments will take more effort, but on a whole a consistent amount of work is required skill improvement
