Magnetographic quality control testing device e.g. for weld seam

The device uses a magnetic recording support (4) applied to the workpiece (1) being tested which is then magnetised to obtain a magnetogram which can be evaluated to verify the workpiece quality. The intensity of the magnetisation field is adjusted in dependence on the max curvature of a liquid drop...

description The device uses a magnetic recording support (4) applied to the workpiece (1) being tested which is then magnetised to obtain a magnetogram which can be evaluated to verify the workpiece quality. The intensity of the magnetisation field is adjusted in dependence on the max curvature of a liquid drop deposited on the workpiece surface. Pref. a magnetic substance (8) is inserted between the workpiece (1) and the recording support (4) for smoothing the workpiece surface. The magnetic substance (8) pref. comprises an adhesive containing dispersed magnetic particles. The magnetisation is pref. effected via. a series of partial coils (11) around a magnetic conductor (9) applied to the workpiece (1).
