Rationale:

Lathe work is mainly used in ships when non standard nuts, bolts and threads need to be prepared. Cast iron is one of the major materials uses in manufacturing ships. Many parts of ships are cast in foundry. Cracks and breakages are formed in ships due to scale formation and corrosion. These damages are corrected by welding. In some cases pipes also need to be joined by welding.

Guidelines:

• Introduction of tools and equipments
• Introduction about lathe and its parts
• Types of patterns
• Types of sand
• Preparation of sand moulds
• Core sands, preparation of cores
• Introduction about welding equipments and accessories
• Types of welded joint
• Edge Preparation.
