REPAIRING WORN-OUT RUDDER BEARING HUB AND PROPELLER BY MEANS OF BUILT UP WELDING
Abstract
The proposed article describes the process of repairing worn-out rudder bearing hub by means of built up welding by the electrode subfusion welding method, as well as, the repair of propeller blades by semi-automatic MIG welding. The technological sequence of the recovery process is described, the used consumables are listed, as well as the technological modes of welding. The main steps of the process are illustrated.
