【Abstract】 A three-dimensional welding line detect sensor is designed based on integration technology.In order to settle the real-time tracking along the welding line during automatic welding manufacture industry,the GMR sensor,welding line detect sensor and proper microprocessor are integrated together,which miniaturizes and intelligentizes the integrated sensor.Due to the problem of nonlinear,levity and the welding is interfered easily by interfere resource such as crator in the welding process,intelligent controlling strategy are used for realizing three-dimensional welding line detect,so the blind fields of detecting are reduced.The experimental result shows this sensor can check three-dimensional space welding line,it has high tracking accuracy,and it can reach the designed technical requirement.更多还原
