汽车车身焊接对螺柱焊接精度要求较高。在普通自动螺柱焊接系统基础上搭建测量设备，进行网络配置、校正参数设置和补偿算法设计，最终研制了一套TCP（Tool Center Point）自动校正系统。该系统有效补偿了机器人和螺柱焊枪的精度误差，大大提高了螺柱尺寸的稳定性和可靠性。该技术在焊接精度要求较高的其他场合也值得参考借鉴。

Automobile welding requires high precision of stud welding. Based on the common automatic stud welding system, the measurement device is established, and the network configuration, the calibration parameter option and the compensation algorithm design are carried out, to ultimately develop a set of TCP (Center Point Tool) automatic calibration system. This system effectively compensates for the error of robot and stud welding gun, greatly improving the stability and reliability of stud size. Such a technology has the potential to be popularized in other occasions where a high welding precision is required.
