After the installation of the transformer , the sealing points will be guaranteed without leakage and the correct readings of every instruments until the handover is up to the grade 6变压器安装完毕后，保证各密封点焊缝无渗漏，各表计准确无误，各项交接试验合格。
A technique of 3 - point positioning of welding seams with structure - light visual sensor is presented . with this technique , arc - welding robots can cope with the location variation of weld seams each time in batched manufacturing . on the base of suitable mathematical description , the localization problem is transformed into determining a displacement transformation matrix 在此系统中利用机器人结构光视觉三点焊缝定位技术，使弧焊机器人可以适应批量生产中每次焊缝位置的变化，通过适当的数学描述，将焊缝定位问题转化为确定位姿变换矩阵。
