ABSTRACT:
A non-destructive inspection arrangement for ferrous and non-ferrous metallic workpieces. The inspection arrangement employs a liquid crystal indicator medium and electrical current flow through the workpiece to develop potential differences across work surface flaws that are to be detected. The concepts of direct application of the liquid crystal medium to the work area surface and containment of the liquid cyrstal medium within a viewing device are also included.
