Abstract

1503050 Detecting flaws magnetically M FORSTER 13 Oct 1976 [13 Dec 1975] 42593/76 Heading G1N An arrangement for magnetographic defect inspection of non-flat surfaces of ferromagnetic bodies comprises a frame 9 movable over a surface of the body 1 under test, two spaced magnet units 79 for magnetising the surface of the body and a feed unit 5 carried by frame 9 and including a pressure wheel 39 arranged to apply a magnetic recording medium (tape) 53 to the magnetised surface between the two magnet units 79. At least one of the magnet units 79 is carried on an arm 7 pivoted to the frame 9 so that the radius of curvature of an arc through the two magnet units 79 and the region therebetween at which the pressure wheel 39 applies tape 53 to the magnetised surface is variable. The magnet units 79 may be mounted on a supporting structure 65 which is pivoted for two degrees of movement on arm 7.
