Contact arc metal separating grinding is a thermal separation process for metal structures in the underwater area. A disc-shaped tool electrode is set in rotation via a water hydraulic drive and at the same time an electric current is conducted from an external welding power source to the tool electrode. After brief contact between the tool electrode and the workpiece to be cut, an arc is struck. The thermal energy of the arc leads to localised melting of the workpiece material and the rotation of the tool electrode creates a flushing effect, resulting in the kerf. The UWTH has an automated, remote-controlled cutting system and a hand-held device to use by divers.
