Laser beam welding receives a technology to make medium application in American ship vessel

5mm less than, need to repeat treatment scarcely, saved many and artificial. The United States uses the laser beam welding of HY-130 alloy steel to receive an experiment to make clear to submarine compression housing, the mechanical function of contact, if rupture intensity, percentage elongation, the performance that compares connect of solder of place of other and groovy method is superior. Concussion test result makes clear, the trends that laser beam welding receives contact is torn off can be close to mother capable person, pound capable person of tenacity excel mother. Current, the laser welder that butt welding receives is in boat board solders the respect already got applied, dockyard of home of know exactly about sth used this kind of welder. Laser beam welding receives large ship board product line, need to deploy commonly: Profile machine treatment and finishing equipment, include horn to roll arenaceous machine of press, successive gush, ink jet to mark implement, plasma cut equipment, deferent system, roll stage, storeroom to wait; Laser operating system, include optics of face of laser source, lens control of stage of system, numerical control, system and testing system; Bracket system, include cut stage to wear, solder stage wearing, remove condole implement, clamping apparatus. The United States dockyard uses Fuketeli collect cut and solder the compositive solution that is an organic whole, built to solder boat board product line, can realize 12m×12m big board butt joint cut and solder, improved manufacturing efficiency thereby, reduced make cost. The advantage that adopts this kind of compositive plan is: When laser beam machining receives a province than blaze cut and arc welding; Space of laser beam machining is little, have big deep wide than; Hot input is very small, because this laser beam machining is not had basically,be out of shape; Stimulate beam of light to be able to come true cut and solder unifinication. 2, marine the laser beam welding of profile receives the United States to be used the earliest large-scale solder of profile is CG-47 class chaser. To reduce the weight of naval ships of this one level, the HSLA-80 that used length to exceed 7km solders profile, replace advocate the hot-rolling profile that uses on housing. The United States had used two kinds of laser beam welding to receive T profile at least on surface ship vessel, they produce in job shops: The laser beam welding that shipbuilding branch produces with HSLA-80 steel receives Yinggeersi T profile, as go instead of light-duty cruiser strengthen costal region board; Company of Ba Sigang iron differs a few kinds sectional profile, the profile that be like horn, T profile and crossed profile use at bracket of missile of chaser air defence. Use laser beam welding to receive profile to will be opposite the shipping design, major effect that creates kimono battle life to produce the following fields: Because get sort of profile of be confined to no longer, it is main consideration element with function, optimize a design around what the target has structural member; Wright can depend on complex three-dimensional component part the deformation outside its to be relatively simple 2 dimension component part, solder accurately more quickly with high power laser for an organic whole, reduce thereby make charge, reduce finishing workload, reduce light-duty ability weight; Right the person that use, use solder profile can reduce operation cost substantially; Because life of component part exhaustion machines precision to rise, solder juncture decreases and get extension, space of ship vessel interior is allocated afresh according to the need of weaponry easily, specific fuel consumption is reduced etc. 3, since covering with tiles arris board laser beam welding receives rolled steel to be used at shipbuilding gently character, to improve the structural efficiency of armor plate, people uses arc solder framework to strengthen all the time board, as board and cabin clapboard. These clapboard ply are opposite thinner, make an appointment with 6~8mm, unless undertake quality is controlled be buildinged strictly, 2 times correctional treatment waste is made an appointment with of 25% build man-hour. Although the twist of large component part and mounting error are OK advanced CAD, production technology and mathematical cut technique undertake have the aid of overcome, but although such, when using arc solder craft to be together single component solder, want to use many welding line metal, welding line metal produces very great leftover stress when caky systole, can bring about be out of shape. use laser beam welding to receive technology, welding line is narrow, solder rate is rapidder, but a few fill or not metal of fill welding line, leftover stress and be out of shape small also. American navy begins laser beam welding to receive ripple to place core board from 1987 (LASCOR) applied research, basically use 0.

6 ～ 1.

The stainless steel plank of 6mm ply. Include to use laser beam welding to receive ripple to place core plate in the solution that the project group that with American navy metallic machining center heads offers to reduce hull weight. Be in early 2003, metallic machining center made 78×240 successfully inch laser beam welding of large corrosion-resisting steel accepts the moire plate that place core, the performance that receives plate of moire with filling to be used at ship vessel to laser beam welding had comprehensive research, include small proportion model test, fire prevention, noise and corrode an experiment, curve intensity of function, compression, shear strength and fatigue function test, solid a light boat applies an experiment to wait. Test result makes clear, use this kind of interlining board to be able to reduce the fireproof, insulation property that increases board or cabin clapboard and structural heft, flatness substantially, apply oiled lacquer and coat easily; And can reduce life period to maintain cost, increase cabin to be able to use a space. Make in the light of what laser beam welding receives ripple to place core board with application, the research that the American navy that American navy started 2004 makes technical laser beam welding receive ripple to place core board plans what acquire 11.8 million dollar in all to aid financially, the data that receives ripple to place core board to laser beam welding, treatment, laser beam welding is received, structural region defends function and cost undertake optimizing study, the purpose is to be American navy to be in CVN21 of aircraft carrier of new-style nuclear power and missile destroyer DDG1000 use laser beam welding to receive ripple to place core board to undertake basic research is mixed offer a technology to support. The base that carries this item uses research, the platform of security personnel of 93 board brim that laser beam welding receives ripple to place core to harden compose already was used at DDG1000 naval vessel and personnel protect protective screen, among them, close half already passed a test, making by AppliedThermalSciences company. Clapboard of the elevator gate that at the same time laser beam welding accepts ripple to place core board technology to will be used in CVN21 of aircraft carrier of new-style nuclear power, cabin, inside the place such as splint, can reduce weight 200 tons reduce production cost. In addition, american navy returns plan general LASCOR board use at CVN-78 class aircraft carrier. LASCOR board will be used at island of watertight door, board, naval vessel, bulkhead to wait. Laser beam welding of machining center of American naval metal accepts plate of moire pod heart 4, every aircraft carrier has the other application United States that laser beam welding receives 4 ejector, every ejector has many 100 to guide about a cover board, the chamfer of cover board area has side of bearing of scroll of an emissive shuttle, emissive shuttle makes the plane is in 3 seconds, when quickening 256km/h, bearing range can occur roll. With chamfer of HY-100 steel control and guide, work in the harsh environment of saline mist and high temperature air current, wear away the surface has corrosion product to generate, these corrosion product have abrasive effect between wheel and orbit, of surface of meeting aggravate orbit wear away. Should guide wear extent exceeds a cover board surface 1.

When 23mm, be about to use guide newly wear cover board to undertake changing. Tatty guides wearing cover board is cannot solder with what have of methodological rehabilitate, using laser frit spread can be feasible, its charge wears the 50%~60% of cover board to guide newly. Current, american navy already received CO2 laser beam welding the technology to be used at guiding to wear the rehabilitate of cover board. CNC Milling CNC Machining
