风电塔架全自动四丝窄间隙埋弧焊技术
Fully automatic four-wire narrow gap submerged arc welding technology for wind turbine towers
摘要
Abstract
To address issues such as low weld seam deviation recognition accuracy and poor adaptability of oscillation control in the multi-layer,multi-pass welding process of medium-thick plates for wind power towers,a comprehensive approach is adopted,integrating theoretical analysis,simulation,experimental validation,environmental construction,and industrial-scale application of ultra-large wind power tower structures(construction of ultra-large,high-reliability offshore wind power tower structures).This includes process feature extraction and modeling of four-wire narrow-gap submerged arc welding(SAW),hybrid seam tracking using arc and laser vision sensing,multi-layer tracking in narrow-gap SAW,and closed-loop real-time control.The research is specifically focused on developing a fully automatic four-wire narrow-gap SAW seam tracking technology that requires no teaching,a mathematical model that is capable of real-time compensation for changes in welding parameters,and dual-sensor integration of arc and visual sensing.Experiments are conducted on 80 mm-thick Q420MC steel plates using four-wire SAW.The results show that the weld surfaces are found to be uniformly formed,and macro-metallographic analysis shows no cracks,inclusions,or other defects.Welding efficiency is improved by 300％,and 100％of non-destructive tests are passed,providing effective technical support for the intelligent manufacturing of wind power tower structures.关键词
