1、The application in the field of sheet cutting

    Laser cutting with the help of laser oscillator output laser beam, under the action of the focusing mirror to produce high density energy, and then melt evaporation on the material, and then achieve the cutting effect, because the energy per unit area can be used to cut slit smaller high-precision products.  Such as an enterprise of fine plasma cutting, plate groove cutting, fiber laser cutting, tube nozzle-vessel junction line drill cut compound all-in-one for John Deere materials, such as komatsu construction machinery manufacturers at home and abroad, including the enterprise of the two-dimensional laser cutting machine, 3d laser cutting machine cutting thickness of the product for 1 to 25 mm of the sheet or shaped,  Cutting material range from pu Q235A to 1000MPa high strength plate, can be cut 20,000 tons per year.  The current construction machinery plate processing industry mainly uses laser cutting machine for carbon dioxide laser cutting machine and optical fiber laser cutting machine, among which carbon dioxide laser cutting machine is an early product, the wavelength is about 1/10 of the optical fiber, in the transmission process and the isolation of the air optical path synchronization.  Fiber laser in the propagation process of higher energy number, better passability makes the heat influence and cutting range smaller, is conducive to improve the utilization rate of sheet metal and cutting efficiency.  

2、The application in welding field

    Traditional engineering machinery welding technology with submerged arc welding, argon arc welding, gas shielded welding form is given priority to, such as welding splash and large deformation problems in the product, and the welding arc and dust will pose a threat to operating personnel health, with technology development, industrial enterprises in improving the quality of welding, reduce operation were studied,  The concept of robotic welding and flexible manufacturing is increasingly used in the automotive industry.  In recent years, some universities in our country for a large number of thick plate welding technology in research, to form the compound, high power laser deep penetration welding, arc ultra narrow gap multilayer wire filling welding and other welding methods, which used in engineering machinery lifting beam composite laser arc welding technique is very successful, such as in automobile crane boom in the welding of high strength steel used.  Compared with the traditional welding method, laser-double wire MAG composite welding can effectively improve the welding adaptability, and can be used in high reflection and difficult to weld dissimilar materials, effectively improve the stability of welding, eliminate welding quality defects, welding efficiency increased by 300%.  Compared with the welding method of single heat source, the welding depth of composite welding is increased by 50%, and the welding speed is faster, and the welding wire consumption can be saved by 30%.  

3、Application in the field of quality management

    In the ISO9000 quality management system put forward the requirements of parts process monitoring, to ensure traceability, so the construction machinery manufacturers in order to trace the quality and use of parts need to develop a permanent identification of the supplier, which includes the name, manufacturer, material number, figure number, production date.  Traditional marking technology using cylinder uninterrupted mechanical shock objects will be under the sign of legacy trajectory, and the operation process of large noise, prone to blur and plate deformation problems of laser marking technology without contact processing using laser beam in workpiece surface moving, product processing is achieved through controlling the movement of the laser path.  Compared with the traditional method, the speed can be increased by 1 times, and the font is clearer, and the complex patterns and symbols can be displayed.  In addition, environmental pollution can be reduced in the contactless processing environment.
