Description
Laser Welding has gained fast-paced applications in most of the industrial applications.

The advantages of Laser welding includes resulting in a high strength welds, using a low heat application, it gives an ultimate precision and it is also responsible for creating a complicated joint. In this MOOC learners will face some basic topics regarding laser welding such as the concept of the keyhole welding process, the parameters which affect the laser beam welding process, and the various methods which can be adapted to increase the laser beam welding efficiency. The MOOC is divided into three sections represented below:SECTION 1: Basics of Laser Beam WeldingSECTION 2: Laser and Process EfficienciesSECTION 3: Methods to improve efficiency
