实现了焊接过程中引弧、旋弧、顶锻的自动控制，操作简单方便。
The device could easily and automatically control arc ignition, arc rotation and upset.
影响闪光焊接头性能的最主要因素包括焊缝区域的温度场分布、闪光顶锻的工艺参数和焊缝区域出现的缺陷组织。
The quality of the FBW joint is mainly decided by temperature field distribution, process parameters during upsetting and the structure defects.
从而成功地实现了对气压焊的焊接压力、气体流量、顶锻位移量等焊接过程参数的控制，并使控制系统具有较快的动态响应速度和较高的控制精度。
So the control of the welding parameter such as welding pressure, gas flux, upsetting length is realized, and the system has a high dynamic response rapid and a high control precision.
