摘　　要：通过对GMAW_P焊过程的研究 ,设计了以单片机为核心的逆变GMAW_P焊系统 ,介绍了该系统的总体结构及其工作原理、控制电路的组成、控制精度的提高和系统控制软件 ,实验结果表明该系统具有系统结构简单、可调参数多的特点 。An inverter GMAW_P welding system is designed in which the microchip is adopted as the central controller through studying the GMAW_P welding process. The structure and working principle of the system and the makeup of the control circuit are discussed in detail. The method of improving the control precision and the system software are also introduced. The result shows that the system has simple structure and many adjustable parameters, which can control the GMAW_P welding process precisely.
