Rationale:

Different materials go into the making of a ship. Cast iron is one of the major materials uses in manufacturing ships. Many parts of ships are cast in foundry. Parts of ships are joined by welding. Different types of welding methods are used in ships. Lathes are used in ships for different purposes.

Objectives:

At the end of the study of III Semester the student will be able to

• Know the various types of moulds and preparation of casting.
• Have knowledge on Welding & heat treatments.
• Know various operations that can be performed in lathe and allied machines
• To equip with the practical knowledge required in the core industries.
