Abstract: In order to detect can weld side-seam flaws or defects an infrared sensitive detector head is used. A collimator fiber optics or an optical mask are used to give a higher resolution. Optical fibers may have a second coating of EMA or an occasional optically absorbent fiber may be placed parallel to the optic fibers in order to cut down crosstalk and introduce an absorbent medium between the fibers. Coherent fiber optics may be used.
Abstract translation: 为了检测可以焊接侧缝缺陷或缺陷，使用红外敏感检测器头。 使用准直器光纤或光掩模来提供更高的分辨率。 光纤可以具有EMA的第二涂层，或者可以平行于光纤放置偶尔的光吸收性纤维，以便减少串扰并在纤维之间引入吸收介质。 可以使用相干光纤。

Abstract: An electronic circuit for receiving the output of one or more detector units which may pick up the infrared emission from a welded seam as it passes by the detector unit or units. The circuit sorts out high and low signals to give an indication of hot or cold spots which indicate deficient welding. The signal is used to operate indicators, counters, and a weld reject mechanism or marking means.
