全位置自动焊管设备可编程序控制系统

Programmable Control System For Tube All Position Automatic Welding Michine

介绍了全位置脉冲钨极氩弧自动爆的工艺过程，设计了PLC的接口电路和编程软件。本系统采用SIEMENS7－200系列PLC进行控制，具有孤长控制和摆动功能，焊接参数四个区间可调，存贮10个程序，可以通过编程器现场编程。

The technical process of all position pulsed argon arc automatic welding is introduced, the interface circuit and control programs are designed. With the arc-control and swing-control functions, the system which is controlled by SIMEN S7-200 PIC has 4 parameter regions and stores 10 programs'and documents programs with the Programming Device on the spot.
