Abstract: The CFB boiler cyclone separator tube panels stud welding mainly adopts manual porcelain ring stud welding or manual gas stud welding, the low degree of intelligence, workers labor intensity, welding quality is not stable. Based on the deficiencies, this paper introduces a cyclone separator tube panels stud robot welding equipment and technology, through the tube panels laser scanning and 3d reconstruction, single tube accurate scanning, welding trajectory planning and other technology research, complete the cyclone separator tube panels stud intelligent robot welding control system software development, so as to realize CFB boiler cyclone separator tube panels stud intelligent welding.The stud weld is beautiful, stable quality, no defect welding and welding tumor.
