PROBLEM TO BE SOLVED: To provide a weld visual inspection device for visually inspecting welds arranged annularly, configured to set a window according to variation of positions of the welds.SOLUTION: A weld visual inspection device includes image processing means 13c for processing a development image 20 formed by linearly developing welds 1b arranged annularly. The image processing means 13c repeats: window setting processing S120 which sets a window W1 so as to include a plurality of welds 1b in a development direction X of the welds 1b; pitch calculation processing S130 which calculates a pitch Px in the development direction X of the welds 1b included in the window W1 set by the window setting processing S120; and window position determination processing S140 which determines the next position of the window W1, on the basis of the pitch Px calculated in the pitch calculation processing S130. |
