the competition of stainless steel quality

The preliminary design, the overall layout of production line for welding of stainless steel laser cutting and 3D laser cutting technology and production line cutting unit were studied. First of all, this production line of the research object - door structure and process analysis, two kinds of welding method, carried out the introduction; this production line cutting unit and the welding unit of the main devices, respectively, carried out the selection, at the same time based on the production line flexibility and security considerations, the overall design of the overall layout of the production line. Secondly, it discusses laser cutting principle and main cutting, lists the three important factors that affect the three-dimensional laser cutting is different from two-dimensional laser cutting, gravity, space curvature radius and workpiece thermal conditions, and a brief description. The focus of some laser pointer can be adjustable.
The three-dimensional laser cutting programming methods and processes; three main difficulties in the three-dimensional laser cutting, the cutting head collision, deformation of the workpiece, the corner had burned, and gives the main method to solve these difficulties. Finally, the three-dimensional laser cutting process carried out in-depth study, the design of the orthogonal experiment, selected several major factors that affect the quality of 3D laser cutting, that is, cutting type, laser power, cutting speed, assist gas type and pressure, and select a cutting width, cutting the surface roughness, surface dross as laser cutting quality assessment parameters. Processing and analysis of experimental data, summed up the influence of process parameters on cutting quality, and provides an effective method to solve the corner burnt. The focus of some laser pointer is fixed which can not be adjusted manually. It is a very sweet and considerate design of  laser pointer for the customer
Keywords: 3D laser cutting; stainless steel box; production line; laser technology; process preface laser cutting and welding technology as an important technology for a country, plays a decisive role in national economic development, its level of a certain sense, can reflect a country industrial level of Stainless steel industry, competition is the competition of stainless steel quality, production costs, competition, economic competition. Therefore, the use of different process parameters of laser cut stainless steel plate, gap size and surface roughness of the stainless steel plate laser cutting of laser process parameters. The adjustable focus of laser pointer can concentrate all energy of the laser beam light emitted by the laser point into a very small dot.
