If the table cells corresponding to the scanned detection area 41 without defects are marked with red, the table cells corresponding to the scanned detection area 41 with defects are marked with green, and the table cells corresponding to the non-scanned detection area 41 are not color-marked. Thus, the operator can intuitively understand the detection result of the weld 101 in real time through the table displayed by the display unit 20. Of course, the detection report of this embodiment may also be represented by other forms, such as a region diagram, a line diagram, a histogram, and the like, and different detection results may also be distinguished in different forms, which is not described herein again.
Referring to fig. 4-6, all the detection areas 41 have the same size, and preferably, the detection areas 41 have the size of 10mm ＊ 10mm, so that all the detection areas 41 can subdivide the entire weld seam 101 into a plurality of parts corresponding to the sizes of the detection areas 41 one by one, the detection accuracy is improved, and when the weld seam 101 is found to have defects, the position of the defect can be quickly located by means of the location coordinate point 411 of the detection area 41.
