摘　　要：通过设计一种对汽车侧围裙边进行移动式多点自动焊接的PLC系统,解决了由于汽车车身的侧围裙边材料薄、壳体体积大、形状复杂等情况导致手工焊接带来的生产效率低和焊接质量不稳定等问题。Aprons edge material of car side is thin, large and complex shape. So it＇s hard to be spot weld by hand due to the spot compression, little edge and narrow workspace. This problem can be solved by a PLC system of mobile multi-point auto- matic welding on the car side apron edge. The system can easily be modified on the part of the welding parameters. The prob- lems of low productivity of manual and some automatic spot welding systems lack of positioning accuracy are solved.
