This, combined with accumulating surface penetrant due to roughness, geometry, insufficient wash off, etc. makes it challenging to train an automated inspection system capable of distinguishing ...

Liquid penetrant inspection, which can locate surface-breaking defects in non-porous materials; Magnetic particle inspection, which can detect surface and slightly subsurface discontinuities in ...

Liquid penetrant testing is a non-destructive method used to detect surface breaking defects in any nonporous material. Liquid penetrant is applied to the surface and is drawn into defects by ...

Nondestructive testing (NDT) is the process of evaluating the quality and integrity of a manufactured part without harming its usability. There are six common NDT methods: visual testing, liquid ...
