What do you call the end joint formed by adjoining plates in hull plating?

The end joint formed by adjoining plates in hull plating is referred to as a butt joint. This type of joint is characterized by the edges of two plates being aligned and joined together, typically using welding or bolting techniques. The primary reason this joint is utilized in hull plating is that it provides a strong connection that can effectively handle the stresses and loads experienced by the vessel's structure.

Butt joints are preferred in many applications due to their ability to produce a smooth and continuous surface, which is critical for maintaining the integrity of the hull and ensuring its hydrodynamic efficiency. Additionally, using a butt joint allows for better distribution of stress over the plates and facilitates repairs, as the joint can be accessed from both sides.

In maritime applications, ensuring a robust joint in hull plating is vital for safety, performance, and structural integrity, especially considering factors such as water pressure and environmental conditions.
