Nautical Term: Close butt
Definition of Close butt
Close butt refers to a type of joint fit where the parts are ground to a very close fit. Once ground to the desired fit, the parts are then pulled tight using clips or other retaining mechanisms. Finally, the joint is welded to ensure a strong and secure connection.
For example, during the construction of a new ship, the hull plates are prepared and fitted together using the close butt method. This ensures that the hull plates are firmly and securely connected, creating a strong and watertight structure for the ship.
