IPC: G01N27/72
Filed: 2000-10-26
Abstract: PROBLEM TO BE SOLVED: To simultaneously detect the position and direction of a weld line or a welding butt section readily by scanning the weld line or the welding butt section only once with one probe. SOLUTION: The probe 11 comprises an excitation coil, where two rectangular coils cross orthogonally and metals M1 and M2, and a pancake-type detection coil that is arranged at a position opposing the weld line W, and both the excitation coils generate a rotating magnetic field by excitation signals whose phases differ by 90 degrees and generates an eddy current Ie. The direction of the eddy current Ie changes, in synchronization with the rotary magnetic field as shown by a solid line for t=0 and a broke line for t=2T/8. When the probe 11 is scanned along a line L, the detected signal becomes zero at the center of the weld line W and reaches (+) and (-) maximum at both the ends. When the inclination of the probe 11 to the weld line W is changed, the phase angle of the detection signal changes. The position and direction of the weld line are detected from the zero value and the phase angle of the detection signal.
