The processing methods and quality of T-joint directly affect the performance of stiffened panels. In this paper, firstly, a ten-six axis dual-beam laser welding system is constituted to research the T-joint welding process. Then, the ten-six axis controller in laser welding system is designed to achieve the accurate controlling for position and attitude of welding head during 3D welding of T-joint. In addition, the real-time measurement on both sides of T-joint is adopted to enable deformation compensation and precise tracking for welding seam. Finally, the T-joint welding tests are carried out and the results show that the welding seam errors are within allowable range. Consequently, the dual-beam laser welding and seam tracking control technology presented in this study can meet the processing requirements for T-joint.
