In the production of auto parts in China, manual welding and special plane welding have been the dominant position in welding production for many years. In recent years, due to the large number of applications of welding robots,The automation level and production efficiency of parts production are improved, and the production is more flexible, and the welding quality is guaranteed.

In the automobile body assembly welding process, spot welding technology is still in the leading position, the application of resistance spot welding technology has realized the mass production and automation of automobile body manufacturing.
Resistance spot welding equipment used in automobile body assembly welding production line mainly includes the following three types:
(1) Suspend spot welding machine is mainly used in positioning welding position on the body assembly welding production line.
Or it is used for welding parts with complex solder joint position (not suitable for automation). Manual work, low degree of automation.
② The advantages of multi-spot welding technology are high production efficiency and small welding deformation. Its disadvantage is that it can not adapt to the production of a variety of models, poor flexibility.
Spot welding robot spot welding robot is widely used in the modern body assembly and welding production line, can improve the degree of automation of assembly and welding production,
Reduce the labor intensity of operators, improve production efficiency, ensure the quality of welding. Spot welding robot is mainly used for body assembly welding repair welding station, body assembly welding station, etc.
Moreover, due to the use of spot welding robot, the flexible production mode of body assembly welding is realized, which is the mixed line production with many varieties and few batches.
Spot welding robot is usually composed of robot body, robot control device, spot welding pliers and resistance welding controller (time controller). The current spot welding robot system uses the following advanced technologies:
, the inverter welding power reduces the weight and volume of the welding transformer, and the transformer and welding tongs are made into an integrated robot spot welding tongs.
The application of integrated welding tongs is beneficial to the track movement and attitude change of spot welding robot within its motion range.
The use of inverter welding power source can also improve the electrical performance of the welding machine, improve the thermal efficiency of the power source, and achieve the purpose of energy saving.
Through the modular design, the connecting interface between the robot welding tongs and the primary side water and electricity piping can be standardized.
With several different types of welding tongs installed in the device, the spot welding robot is programmed to automatically replace them in a matter of seconds. Realize quick and automatic replacement of welding tongs,
To achieve the use of a spot welding robot can adapt to the requirements of various parts of the body welding, but also can adapt to the needs of the production of multiple models.
Thirdly, the robot control system can not only control the movement of the robot itself, but also automatically control the resistance welding controller.
Issue welding start command, automatically control and adjust welding parameters (voltage, current, pressure, time cycle), control the size of the spot welding clamp stroke and clamp release action.
At the same time, it also has the functions of automatic fault diagnosis and alarm, such as the fault alarm when the electrode is adhered to the welding parts and the compressed air pressure is too low.
(2) in the arc welding production of automobile body assembly welding, manual repair welding is mainly carried out in the main welding position of the frame and floor, etc., and the application of solitary welding robot is used in the welding station of the sub-frame assembly workpiece.
