锅炉集箱管座机器人焊接试验工作站的设计与实现

Design and Realization of Intelligent Welding Test Workstation for Tube Base of Boiler Header

集箱是电站锅炉系统的重要组成部分,为解决集箱材质众多、尺寸不一等问题,采用3D视觉技术,通过对焊道的定位,结合管座坡口的尺寸参数实现集箱的自动焊接,以提高锅炉集箱管座焊接试验效率和焊接质量。研制了针对集箱管座的智能焊接试验工作站,开发了包括三维图形界面显示、工艺智能规划等功能模块的工艺专家软件,并进行了φ54×9.5管座焊接试验,获得的焊缝成形良好。实际应用表明该焊接工作站智能程度较高,焊接质量满足工艺要求。

The header is an important part of the power station boiler system.In order to solve the problems of numerous materials and different sizes of the header,3D vision technology is adopted to realize the automatic welding of the header by positioning the bead and combining the size parameters of the pipe socket groove,so as to improve the efficiency and welding quality of the boiler header pipe socket welding test.Based on this,an intelligent welding test workstation is developed for the header pipe seat,and a process expert software is developed including 3D graphical interface display,process intelligent planning and other functional modules,and the welding of the header dense pipe joint is completed.The practical application shows that the welding workstation has a high degree of intelligence and the welding quality meets the process requirements.
