• In modern large-scale steel plant, whether it is heavy steel, light steel structure, or in buildings, equipment, ships, and other different steel industry, cutting material in the production chain are the first channel key manufacturing processes, "cutting and welding" Su Iron and steel tailor said, which mainly refers to the application of the wide range of large thermal cutting. Thermal cutting began in the beginning of the last century, acetylene gas cutting by hand in France, then in the world wide popularity of long-term follo

  • Cutting quality control plasma cutting machine, mainly refers to the inclination of the cutting surface finish. This paper describes the cutting speed, working pressure
    Relationship between cutting quality. CNC cutting machine according to the characteristics, combined with experimental data were analyzed and summarized, reached a different power cutting different thickness steel
    Optimum cutting parameters plate. To provide reference for improving cut quality CNC plasma cutting machine.

  • aiming at the reason that cutting piece comes into being distorted about the CNC plasma cutting machine,the analysistowards the distortion of cutting piece in this paper.according to the characteristic of CNC plasma cutting machine,it could improvethe process guality of cutting piece in effect for choosing proper technics,for example,cutting section point,aspect,seguence,speedetal during the period of processing,and elaborating towards the distortion control of single side piece, slightness piece,profiled pieceand particularity piece at th

  • In recent years, with the continuous improvement of the level of China's manufacturing industry, CNC plasma cutting machine in the industrial enterprises have been widely used to improve China's machinery manufacturing industry as a whole. As a result of CNC plasma cutting machine in the course of the use of a large number of smoke and dust, filled the entire manufacturing plant, not only endangering the health of employees, but also to the atmosphere pollution, so more and more enterprises attention and attention to modern industrial dust and

  • it will cause a lot of rework, waste of labor, waste materials; thin bulkhead deformation is also large, firework correction workload. This also increases the cost. Another method is the use of professional angle welding equipment. This method is fast, high efficiency; forming good, repair less; but the equipment is more expensive, equipment operation on the workers demanding, such as equipment damage repair more trouble, the high cost. Generally only in the demanding use of steel welding, the hull sub-production used, it is not worth. The pursuit o

  • Machine mainly by the welding car, solder tray, electric control box, wire tray, welding power supply and cylinder transfer tire composed of six parts. The working principle of submerged arc automatic welding machine for inner ring welding of boiler is shown in Fig.1. Welding car is the core part of the welding power supply, simplified tire and wire to send conventional equipment.

  • This article researched vertical fillet once forming welding technology,which including:a set of automatic control system which matching moltenpoor'rise velocity and the upward travel speed of welding tractor;fits for fillet weld and special water-cooled shde block sharped in forced cooling of weld;a set of reconditioner,which can adjust angle for welding fun and water-cooled shde block at horizontal plane.Wiht the help of electrogas welding technology。the vertical fillet once forming welding technology filled the
    gap in welding field.

  • The welding process is stable and the welding surface is clean and the welding quality is improved. Fast, reducing the welder for the electrode or change the posture or rest time, greatly improving the productivity; can be a one-time long-distance welding, welding process splash small, less smoke, one person can operate two devices, greatly reducing the labor intensity.

  • In the steel structure project is usually encountered H-shaped flange plate wide and smaller cross-section, door submerged arc welding arm and H-shaped steel wing
    Edge plate interference, the door submerged arc welding can not be normal welding; or the case of small cross-section can not normally use the door-type double wire submerged arc welding and other issues.
    In view of the above two types of components encountered in the welding problems, I have practical experience in the original gas shielded welding equipment to change

  • Welding as a special mode of operation, its harsh operating environment and high skill requirements, resulting in its employees have been short of high-skilled operators is "a carpets hard to find." In recent years due to the development of the industry and the domestic labor shortage of the environment, further exacerbated its employment gap, so the automation of welding operations is imperative. As a professional manufacturer of automatic welding equipment, we believe that based on the particularity of welding operations, welding a
