A Method of Welding Seam Tracking for Arc-Welding Robot by Current
-
摘要: 本文介紹了弧焊機器人在進行"V"型坡口對接焊或角接焊時,為了跟蹤焊縫軌跡而進行的焊縫位置檢測方法-電流檢測法.通過對焊接電流信號的數字處理,提取了反映焊槍與焊縫相對位置的特征信號,定時向機器人控制器提供修正信號,從而使固定在機器人手臂上的焊槍準確地跟蹤焊縫.Abstract: This paper introduces a method of welding seam tracking when arc-welding robot is applied to welding of shape "V" or angle connection. By processing the current of welding with a way of digital signal processing,the feature signal which reflects the position of welding seam is abstracted. And then transmitted to the robot controler in order to trace the seam.
