双语例句
- In this paper, the weld pool is excited by pulsating welding current which is produced by superimposing a certain frequency sine wave current on the straight polarity DC current, and the oscillating signals of weld pool can be detected through arc voltage signals in travelling TIG welding.
本文在恒定直流之上叠加定频率正弦波电流做为脉冲焊接电流激振熔池，在连续行走焊接时，通过电弧电压检测熔池振荡即熔池尺寸。
