中文摘要：实时检测焊枪的前后倾角,实现焊枪姿态的及时校正,是保证焊缝跟踪精度与焊缝质量的重要因素。通过建立带倾角的旋转电弧弧长数学模型,提出一种带收敛系数的积分差值法来实时检测焊枪相对于焊缝的前后倾角。最后,通过Matlab/Simulink仿真和试验对该方法的正确性和有效性进行了论证。
英文摘要： In order to get good precision of welding tracking and weld quality. The pre and post dip of welding torch should be detected real-timely, and the posture of welding torch may be corrected. The mathematical model for arc rotating with dip was built. To detect the pre and post dip angel between the welding torch and welding seam, the integral difference with contraction coefficient was proposed. At last, the validity and efficiency of the method was proved by Matlab/Simulink simulations and experiments.
