As show alive bound economy (ì of J ī Ng J) flying development, of happen by chance of people life division accelerate ceaselessly, increasingly quick traffic means method more and more the pressing demand that makes people. Laser makes mark machine is to use the corporeal face that washs beam of light to be in all sorts of differring to make permanent number. The effect that makes bid is carry surface layer material evaporate show deep-seated matter, the chemical physics that perhaps brings about surface layer material through light energy changes and quarter " of " gives a mark, perhaps carry material of part of light energy burn-up, show the design that requires quarter corrode, character. Railroad and people live daily be closely bound up (Related) , it is one of main component of traffic hub, it is the infrastructure with important country () of ī of Sh è Sh, the personal interest that matters to people directly (Benefit) . To improve the operation efficiency of railroad effectively, railroad development is main now forward the way such as van of burden of car of high speed passenger car, subway passenger car, light rail, high speed develops, want to realize these demand, must undertake to train light quantify processing () of ǐ of Ch ǔ L. Commonner now practice is the production process in the passenger car (aluminium alloy data is used in Ng) of é of Gu ò Ch (Material) , because aluminium alloy material has quality light, be able to bear or endure corrupt erode, the exterior is smooth, OK create complex curved surface, more advanced than intensity character, can reduce passenger car obstruction and quality effectively thereby, increase burden. To improve the treatment efficiency of aluminium alloy material and the safety that ensure a passenger car effectively, the treatment means method that changes a tradition with respect to need uses laser technology to undertake machining production. Laser technology creates medium applied field in railroad passenger car now basically is stock of seam of the makings below plank and profile, crucial part, automatic product line carry and mark the place such as transplanting, have treatment rate fast, workpiece is out of shape small, precision is OK and tall, economic material (the character such as Material) . Laser makes mark machine is to use the corporeal face that washs beam of light to be in all sorts of differring to make permanent number. The effect that makes bid is carry surface layer material evaporate show deep-seated matter, the chemical physics that perhaps brings about surface layer material through light energy changes and quarter " of " gives a mark, perhaps carry material of part of light energy burn-up, show the design that requires quarter corrode, character. Laser beam welding is received machine 70 time basically use 20 centuries at soldering Bao Bicai expects and low speed solders, solder the process belongs to heat to conduct model, stimulate ray radiation to heat namely workpiece surface, exterior quantity of heat conducts inward ministry to diffuse through heat, power of the width that passes control laser pulse, energy, peak value and repeat the parameter such as frequency, make workpiece fused, form specific bath. As a result of its distinct advantage, in applying the nicety of Yu Wei, small-sized spare parts successfully already to solder. Laser makes mark machine is to use the corporeal face that washs beam of light to be in all sorts of differring to make permanent number. Laser hits sign chance to differ according to laser can divide for CO2 laser laser of the machine that make bid, semiconductor hits laser of sign chance, YAG to hit sign chance, fiber-optic laser to make mark machine. Computer control system is whole laser control of the engine that make bid and commanding center, also be the carrier that software installs at the same time. Laser hits sign chance to should be in as far as possible without dirt, 10 ℃ - use in the environment of 35 ℃ , carry optical parts of an apparatus or appliance dry, without dirt. Laser hits sign chance to basically apply at a few circumstances that ask more careful, precision is taller. Laser beam welding is received machine it is the machine that laser material treatment uses, often call laser welder, laser welder again, by its working way often can be divided burn welder for laser mould (the hand is moved solder machine) , automatic laser beam welding receives machine of machine, laser spot welding, fiber-optic transmission laser beam welding machine, light solders is the laser pulse that uses high-energy amount undertake the local heating inside small area to material, laser radiant energy passes the interior of oriented material to diffuse through heat, the purpose that specific bath forms to solder in order to achieve after material is fused. Use present laser technology to undertake machining not only OK and effective assurance the firm sex of orbit train, use computer to undertake controlling at the same time (the fine rate that Control) can control treatment workpiece effectively, the process that still has treatment (in Ng) of é of Gu ò Ch won't the surface of loss treatment workpiece, the exterior is elegant, different measurement can be controlled accurately. Break up like present laser machine (utility: Metallic cut, metalloid cut) , laser beam welding receives machine, laser to hit sign chance, fiber-optic laser to make mark machine, apply in present railroad treatment industry extensive, as now the constant change of orbit train demand, the orbit train of diverse demand is developing different type ceaselessly, to satisfy the treatment requirement of these diversification, use present high pay to machine means method to undertake machining production with respect to need, and the application of laser technology is a kind among them. Believe to be in before long a travel that orbit train will allow people in the future is more convenient, safe, efficient, and the laser technology application in orbit train production industry also is met more close together.
