More about this course

The course focuses on understanding the science behind technology of primary production processes namely casting, forming and welding. Conventionally, the courses on manufacturing processes deal with study of operational procedures
It is desirable to know how any process occurs and the products are finally manufactured, the basic principles behind these processes are required to be highlighted
The course will make the students aware with the theoretical aspects of the different manufacturing processes mentioned above
The course has been divided into three sections namely casting, forming and welding, each being covered in 4 weeks of time
The underlying principles of solidification, fluidity, gating, risering, melting etc. will be covered in casting section whereas mechanics of metalworking, analysis of different metal working processes will be covered in the second section i.e. forming
In the third section i.e. welding, principles of welding processes, thermal effects, weldability etc. will be covered
The course will enable the students be conversant with working principles so that they can use the knowledge gained towards increasing the productivity of manufacturing industries in the long run
