英文摘要	This essay based on X-ray digital automatic detection as a starting point, and then to deal the typical X-ray digital image with median filtering and histogram threshold processing, with the help of a column gray method to extract respective column of each weld image gray scale curve, this essay tries to analyze the defect signal characteristics and discuss the extraction methods. In this essay, the author compiles the image preprocessing procedure, columns, gray-scale extraction procedure and defect alarm procedures; and also tries the X-ray weld defect detection of digital rapid recognition and prompt functions. Thorough the analysis we can draw the conclusion that column gray method can be used as a dynamic test basis of automatic alarm decision.
