Dye penetrant testing is a non-destructive test method, which is widely used in the detection of surface-discontinuity defects in metals and non-porous materials. This is an inspection technique to determine cracks, porosity, seams, and leakages, which can affect the structural integrity. Dye penetrant test has been highly demanded in quality control in marine and offshore, manufacturing, and industry, where the elements are to meet safety and compliance criteria with minimum downtime and repair.
