| 摘 要： | 基于一个脉冲过渡一个熔滴且熔滴体积不变的思想,提出了在峰值电流和基值电流不变的条件下采用送丝速度预置和峰值弧压调节峰值时间与基值时间的控制方式。试验结果表明:采用这种控制方式,能够在不同送丝速度或不同干伸长下实现一个脉冲过渡一个熔滴且熔滴体积基本不变。

| Abstract: | From the viewpoint of transfer of one droplet per pulse and a constant droplet volume,the paper puts forward a control mode in which the peak current and background current are fixed,while peak timeand background time are presetted by the wire feed rate and adjusted by the peak arc voltage.The experimental results show that this control mode can realize the transfer of one droplet per pulse and keep the droplet volume constant though exist different wire feed rates or different wire extensions. |
