The invention relates to an underground composite wet process welding device which comprises a microwave generator, a microwave controller, a microwave irradiator, a waveguide tube, a mica plate, a welding gun clamping device and a welding gun. The microwave controller is connected with the microwave generator through a wire. One end of the microwave irradiator is connected with the microwave generator. The waveguide tube is located on the outer side of the microwave irradiator, and the mica plate is arranged at one end of the waveguide tube. The welding gun is installed on the welding gun clamping device. The end, provided with a contact tube, of the welding gun is located in the waveguide tube, and the contact tube penetrates through the mica plate. According to the underground composite wet process welding device, vibration heating is conducted on water through microwaves, water is warmed and vaporized, the influence of the water on welding is reduced, the microwaves have the compressing function on electric arcs, the energy density of the electric arcs can be improved through electric arc compressing, the depth of fusion of welding is increased, the welding quality is improved, and a weldment weld joint can be preheated and slowly cooled through microwave heating.
Description
technical field [0001] The invention relates to the technical field of underwater wet welding, in particular to an underwater composite wet welding device and method. Background technique [0002] Underwater welding is a key technology for submarine oil exploitation, marine engineering manufacturing, submarine pipeline maintenance, etc. At the same time, underwater welding is also an important application technology in national defense construction, and it is used for emergency repair and sea rescue of offshore ships. Underwater wet welding, due to the existence of water, leads to large heat loss and increased residual hydrogen, which ultimately leads to poor weld quality. The traditional underwater wet welding method cannot effectively avoid the influence of water. Contents of the invention [0003] In view of this, the object of the present invention is to provide an underwater composite wet welding device and method to solve the technical problems in the prior art.
