Liberation J6 heavy truck as a new upgraded product launched by FAW Group in 2007, has a great change in the product structure of the cab compared to the J5 series, in order to ensure the sealing, safety and stability of the cab products. And consistency requirements, but also made a great breakthrough in the selection of welding equipment, becoming an advanced model of the domestic cargo truck industry at that time.

The body welding is still based on spot welding, and the number of solder joints is around 4,000. Arc welding is used for the side rails, door hinges and parts that cannot be achieved by individual spot welding. The conventionally used seat type spot welding machine (with nut conveyor), integrated suspension spot welding machine, MIG welding machine, the automatic production line uses a large number of welding robots, which has poor weldability and labor intensity compared with manual welding. , the work environment is poor, the quality of welding is difficult to guarantee, etc., robot welding has considerable advantages.
At present, there are many models of product platform series, and the demand for flexibility of the production line is getting higher and higher. Through the software program programming of the robot and the vehicle management system control of the production line, it is easy to solve the welding problem of the multi-variety cab.
Servo torches are gradually being used in automobile manufacturers due to their excellent characteristics. In order to better understand the advantages of servo welding system, our factory purchased a set of ABB spot welding robots in the first half of 2011, equipped with Nanjing Xiaoyuan servo spot welding gun. After several months of production trial operation, we The advantages of the servo welding torch are mainly realized in the following aspects: 1 The impact of the electrode when contacting the workpiece is small, the electrode life can be significantly improved, and the noise of the working state is small. 2 The welding efficiency is high, and the efficiency of the power frequency welding torch can be increased by 30% to 40%. 3 welding spatter is small, the solder joint quality is good. 4 electrode wear automatic compensation, also guarantees welding efficiency and solder joint quality.
The spot welding robot matched by the servo welding gun and the pneumatic power frequency welding gun is different, including the hardware system and the software control system. In comparison, the previous investment of the servo welding gun is relatively large, but it does have the advantages that the conventional pneumatic welding machine cannot have. .
In short, through the practical application in the future production, the research on the performance, maintenance and energy saving of servo welding guns is believed to provide valuable reference and reference for future process planning.
