Typical Application of Automatic Welding in Automobile Field

    Looking at the welding status of the whole automotive industry, it is not difficult to analyze the welding development trend of the automotive industry as follows: the development of automated flexible production system. Industrial robots, due to the characteristics of automation and flexible production, have been widely and rapidly used in car production in recent years. In the field of welding, spot welding robots and arc welding robots are mainly used. Especially in recent years, automobile manufacturers attach great importance to welding automation. For example, the automation rate of 13 production lines of JETA body welding workshop imported by FAW is over 80%, and each line is controlled by computer (programmable controller PLC-3), which can automatically complete the transmission and welding of workpieces. The welding is carried out by 61 R30 coordinate robots and G60 elbow robots. The robot drive is controlled by a computer, and the input and output programs of the tape recorder are displayed numerically and literally. The robot adopts point-to-point sequential trajectory, which has a high level of welding automation. It not only improves working conditions, improves product quality and productivity, but also reduces material consumption.

    Ultrasonic automobile welding equipment is mainly used in automobile door welding, automobile instrument welding, automobile lamp mirror welding, sunshade welding, interior decoration welding, filter welding, reflective material welding, reflective track nail welding, bumper welding, cable welding, motorcycle plastic filter welding, radiator welding, manufacturing. Dynamic tank welding, oil cup welding, water tank welding, oil tank ultrasonic welding, wind pipe ultrasonic welding, tail gas purifier ultrasonic welding, tray filter plate ultrasonic welding and so on.


Application Trend of Welding Robot in Automotive Industry

    With the development of automobile industry and the continuous improvement of automation level, it provides a good opportunity for the rapid growth of welding robot market. It is expected that the demand for welding robots will increase by more than 30% in domestic enterprises. From the perspective of the development trend of robotics technology, welding robots continue to develop in the direction of intellectualization, perfectly realizing the group coordination and integrated control of robots in the production system, so as to achieve higher reliability and security. The automobile manufacturing enterprises using welding robots will surely achieve rapid development under the conditions of high technology, high quality and low cost, and will also bring new vitality to the development of the automobile industry.

Ultrasonic welding characteristics:

- The welding speed is fast, the welding strength is high and the sealing is good.

- Instead of the traditional welding/bonding process, it has the advantages of low cost, clean, pollution-free and no damage to the workpiece.

- The welding process is stable. All welding parameters can be tracked and monitored by software system. Once the faults are found, they can be easily removed and maintained.
