Man with an industrial boiler suite and laser protective goggles using an industrial laser cleaning machine to clean rust from the hull of a ship. The laser leaves behind it bands of clean metal. The laser machine comprises a small handheld optic tool connected with a conduit to a short electronic rack on a wheeled trolley. The man holds the optic tool approximately 200mm from the surface of the ship that he is cleaning. The beam is yellow but barely visible. The beam makes a line of intense brightness on the metal surface of the ship vertical to the direction that the worker is cleaning the surface of the ship. The ship is suspended in a dry dock. Other refurbishment and painting operations are happening on the ship in the background. Mehr sehen
