Abstract (en)
[origin: WO2008056062A2] The invention relates to a device for automatic under-water welding for making a welding joint (3) on a surface (2), of the type comprising a welding torch (20) including an electrode (21) surrounded by a protection envelope (23) that defines together with said electrode (21) an annular channel (24) connected to means for supplying a protection gas. The welding torch (20) is provided axially at the centre of a set (30) of two concentric envelopes (31, 32), one of which at least is capable of axial displacement and can be adjusted relative to said surface (2), said envelopes defining between them an annular gap (34) for injecting a flow for drying the welding area and keeping it away from the water.
