• C. Drilling, cutting, and stitching
• D. Plastics, adhesives, and sewing

Answer: (B)

The techniques commonly used for joining ship materials include welding, riveting, and bolting, each of which serves a specific purpose in ship construction.

Welding is a widely used method that involves melting the base materials together to create a strong joint. This technique is crucial for joining metal structures, providing high strength and resistance to stresses encountered at sea. Different types of welding, such as arc welding and gas welding, can be employed depending on the materials and the construction requirements.

Riveting is another traditional method that involves driving a metal pin through overlapping pieces of material and then deforming the end of the pin to secure the joint. This technique was historically significant in shipbuilding, providing structural integrity before the advent of welding became more common.

Bolting involves the use of bolts and nuts to fasten materials together. This method allows for easy assembly and disassembly, making it a practical choice for components that may need to be removed for maintenance or repair. Bolts can effectively connect various ship components, from hull sections to deck fittings, ensuring structural stability.

These joining techniques are essential for constructing a robust and durable vessel that can withstand the harsh conditions of marine environments.
