| 摘 要： | 本文所叙述的钨极氩弧焊弧长自动调节装置,采用电弧电压闭环控制,电动机转速开环控制,结构简单、可靠.利用晶体管桥式电路对伺服电动机供电,可避免继电器触点所带来的不可靠性,从而使工作寿命大大地提高。系统的放大倍数在10~6以上。电压控制的精度可达±0.114伏以上。文中还分析了弧长自动调节的静态过程,提出了供这类机构设计的理论依据。两年的生产实践证明,弧长自动调节装置对改善钨极氩弧焊是十分重要的。

| Abstract: | The arc-length control device for TIG welding described in this paper has a closed-loop circuit voltage control and an open loop circuit servo-motor speed control.It is simple in construction and reliable in service.The servo-motor,powered by a transistor bridge,suffers no troudle from relay contactors and therefore makes the life of the device much longer.The amplification factor of this system is over 106 and the accuracy of voltage control is within ±0.114V.The static process of arc-length regulation has been analyzed,thus providing a theoretical basis for the design of apparatus of this kind.The production experience in the past two years has proved that this device is a very useful tool for TIG welding. |
