Weldability of Ship Plates

Weldability refers to the ability of a material to be welded, meaning to be brought together by heating or melting and then allowing the parts to solidify into a single, strong joint. In the shipbuilding industry, welding is an essential method of joining various components of the hull, such as plates, frames, and stiffeners, to create a structurally sound and watertight vessel.
