Measurement of micro weld joint position based on magneto-optical imaging
Measurement of micro weld joint position based on magneto-optical imaging |
| Fig.#cod#x00A0;7. Different intensity of magnetic field corresponds to MO images and voltages of magnetic field excitation setup. a Original MO image of weld joint, b clipped middle 300 columns of the original MO image, c grayscale image, d grayscale corresponding to the intensity of magnetic field. e#cod#x2013;i Intensity of magnetic field corresponding to ordinate of MO images. Weld joint widths are e 0#cod#x00A0;mm, f 0.05#cod#x00A0;mm, g 0.10#cod#x00A0;mm, h 0.15#cod#x00A0;mm, and i 0.20#cod#x00A0;mm, respectively. |
