摘　　要：针对现有管板群缝焊接设备存在自动化程度低、重复定位不稳定等问题,开发了一套管板群缝数字化焊接控制系统,以运动控制器为基础,负责设备整体焊接流程,并配合上位机软件与相机联合运行,为控制器提供焊接参数与运动参数。该控制系统重复定位精度满足设备焊接使用要求,X,Y,Z方向极差分别为0.06,0.05,0.167 mm;不填丝自熔焊接与填丝焊接均无气孔、焊接未熔合与管壁烧穿等现象,且满足外观检测、渗透检测与角焊缝厚度检测要求,为全自动、智能化焊接设备提供研究基础。For the problems of low automation degree and unstable repeated positioning on the existing welding equipment for tubesheet group seams, a digital welding control system for tube sheet group seams was developed.The system is based on the motion controller and is responsible for the overall welding process of the equipment, and cooperates with the host computer software and the camera to provide welding parameters and motion parameters for the controller.The repeated positioning accuracy of the control system meets the requirements of equipment welding, and the ranges in X,Y,Z direction are 0.06 mm, 0.05 mm and 0.167 mm, respectively;There is no phenomenon of pores and incomplete fusion, etc.for self-fusion welding without filler wire and welding with filler wire.The system meets the requirements of appearance detection, penetrant inspection and fillet weld thickness detection, which provides a basis for research of automatic and intelligent welding equipment.
