| Abstract: | A method of weld detection and track control using prepositive sensor is introduced.The multiplex sensor is formed by GMR electric bridge and whirlpool sensor,in which GMR electric bridge is used to detect the height,and the differential measure coil of whirlpool sensor is used to detect the weld center deviation.It compensates the output signal of measures coil by compensating winding which eliminate the phasic and amplitude infection of the wrong brige,software method is used to correct the signal range change which caused by high variety.FIFO queue is founded to save the detection data between welding torch and prepositive sensor,and the method of clustering and lineal inset value is used to eliminate scar infection.Verified by experiment,it can meet the requirements of weld detection and track control in the different kinds of body pots. |
