摘要 2016年的春天,一场焊接行业盛会将在中国经济、金融、贸易、航运中心——上海激情上演。这是一个凝聚人心的时刻:中国焊接博览会重回春季,与中国国际五金展资源整合、联秧举行,30年的焊博会将迎来大放异彩的先进焊接技术、精彩纷呈的智能装备;"焊博会30周年"和"重器脊梁焊接铸就"纪念颁奖活动,将充分彰显焊接行业永续进步、核心价值、品牌实力和成就国之重器中华脊梁的自豪和骄傲; Aceurate seam tracking is prerequisite for laser welding.During butt joint laser welding,the laser focus must be controlled to follow the weld trajectory accurately.An approach to detect the micro-gap weld seam (seam width less than 0.05 mm) based on the magneto-optical imaging is proposed. The weldments were magnetized by using an excitation magnetic field.Meanwhile ,a magneto optical sensor based on the principle of Faraday magneto effect was applied to acquire the magneto optical images of weld seam.By analyzing the magneto-optical images of weld seam, the weld seam center position could be extracted and was used for the state vector.Then the state equation and measurement equation based on the weld seam center position were established.In order to eliminate the interference of process noises, the Kalman filter algorithm was applied to get the optimal estimation of the seam center position.Experimental results indicated that the Kalman filter could effectively reduce the noise interference,and improve the accuracy of seam tracking during laser welding.
