Beschreibung
Zusammenfassung:	Apparatus for the underwater welding of metal structures comprising a hermetically sealed housing wherein are accommodated an electric motor and a reducing gear immersed in a lubricant which is dielectric material. In the housing there is provided a built-in membrane for transmitting the pressure of the environment onto the lubricant contained in the housing chamber so as to improve its hermetic sealing. A coil and rollers for winding an electrode wire and for feeding it into a flexible hose are arranged in an enclosure also made of a dielectric material. Means for electric motor control and a power supply source for the motor are situated outside the housing and the enclosure of the apparatus, being connected therewith via a chain of electric wires or cables.
