Background technology
The welding method kind of current application is very various, to adapt to various connection states and to the welding of different materials.Friction welding is under pressure, friction by interface to be welded raises interface and near temperature thereof, the distortion of materials drag reduces, plasticity improves, the oxide-film fragmentation at interface, be accompanied by the material production plastic deformation and flow, by the diffusion on the interface and again the crystallization metallurgical reaction realize the solid welding method that connects.Connection, production efficiency height, dimensional accuracy height, equipment that friction welding possesses joint quality height, suitable foreign material are easy to outstanding advantages such as automatic and mechanical, clean environment.Especially, for some occasion of arc welding application difficult, for example underwater steel construction reparation, the friction welding that belongs to Solid-phase welding possesses unique environmental adaptation advantage.
Alternative method of attachment under water is divided into 3 classes, i.e. mechanical connector, arc welding and Solid-phase welding.Mechanical connector is simple in structure, relatively cheap, install rapidly and quality of connection has nothing to do with the depth of water, but the existence still of its this tender subject of long-term reliability makes its application be restricted.Arc welding is divided into WET WELDING, local dry-type welding, dry-type high-voltage welding and the welding of dry type normal pressure.WET WELDING, local dry-type quality of weld joint are lower, are generally used for shallow water, non-important structure reparation.The dry-type high-voltage welding can obtain high-quality weld seam, and the underwater dry-type maintenance system of extensive use at present adopts the welding of rail mounted tungsten argon arc, but because arc stability reduces, is generally used for the 300m depth of water with shallow.The variation mode PLASMA ARC WELDING of tungsten argon arc welding and gas metal-arc welding connect can realize that the 1000m depth of water is with the welding under the dark pressure; but; implementation cost is high, it is full-automatic to be difficult to realize, and is difficult to be applied to the maintenance of other steel constructions such as ocean platform outside the submarine pipeline.The dry type normal pressure welding then cost than the dry-type high-voltage welding is higher, is difficult to apply.Belong to the explosive welding of Solid-phase welding, because, fail to apply for implementing the worry that safety is given birth to.Belong to the friction welding of Solid-phase welding equally, then obtained more widely using among ocean engineering, for example, the friction stub soldering equipment is under water under the support of remote-controlled robot, finished the depth of water near 400 meters sea risers anode annex welding.But this friction welding can only be finished the simple task that similar double-screw bolt connects, and can not finish complex tasks such as submarine pipeline breakage, ocean platform Crack repair.
In order to reduce the underwater maintenance operating cost, to improve repairing quality, particularly adapt to the needs that marine petroleum development has entered super deepwater field, the utility model proposes the friction stitch welding experimental provision that is used for friction stitch welding research.
