Abstract：Toaddress theproblems oflarge qualityfluctuationsandlowproduction eficiencyassociated with traditional manual welding of ultra-long and complex PV support frames，this study proposes a robotic automatic welding workstationsystem integrated with laser vision sensing.The system's control strategy combines ofline programming with path compensation;ituses laser scanning to obtain the 3D morphology of weld seams inrealtime，accuratelyidentifies weld characteristics，and dynamicall corrects the welding trajectory in a timely manner.Thecontrol system is builtonacollborativearchitectureofPLCand industrial robots，and integratesamulti-axis linkagecontrolalgorithm to precisely match the welding posture and process parameters.Based on the material properties of Q355B steel for the support frames and the groove form，process parameters such as welding current，voltage，speed，and layerdistribution were scientificallyoptimized，and process verification tests were carried out.The results showthat the system ensures high stabilityof weld formation quality，meting the GB/T19418 Grade B standard；meanwhile，the welding efficiency is improved by 69% ，demonstrating the technical feasibility of its popularization and application in intelligent welding production lines for steel structures.

光伏支撑架作为太阳能发电系统的关键承重结构，其焊接质量直接影响整体系统的安全性，但超长复杂钢结构件由于其存在尺寸偏差、装配累积误差、热变形等特征，导致传统“示教再现”型机器人难以适应实际焊接路径的动态变化，容易出现焊偏、未熔合等问题，严重限制焊接自动化进程。（剩余6081字）
