Control Technology for Dual-Beam Laser Welding and Seam Tracking With Ten-Axis Six-Linkage CNC
T 型接头常见于大型构件的筋壁板,其加工方法和质量往往影响着整个结构件的性能。研制了十轴六联动双光束激光焊接机床,其中六轴联动控制单元实现了在三维激光焊接中对位置和姿态的控制,同时对T 型接头两侧进行实时焊缝测量,实现了对双侧焊缝的跟踪与补偿。通过对试验件的焊接,验证了十轴六联动双光束激光焊接及其跟踪控制系统满足大型结构件三维T 型接头加工要求。
Abstract
T type joints
which often affect the quality of the whole structural parts
are widely used in the stiffened wall plate of large components. In view of the above problems
a dual-beam laser welding platform is built to meet the welding requirements of large size structural parts. Then
the ten-axis six-linkage CNC system is designed to meet the needs of both sides welding of T type joint at the same time. While controlling the position and attitude of the 3D welding
the welding seam measurement and tracking compensation on both sides of the T type joint are realized simultaneously. Through the actual welding experiment
the control system of dual-beam laser welding and seam tracking with ten-axis sixlinkage is tested and the result shows it can meet the processing requirements for T type joints.
