Liquid Penetrant Testing

PT Inspections
Since 1967, ATS has been a leading NDT company offering a wide variety of services to many industries.

One of Applied Technical Services (ATS) most popular inspection methods is dye penetrant testing. Many of our customers request this method because it is highly sensitivity to small surface flaws and discontinuities. It also can be used on a wide variety of shapes and materials ranging from metals, plastics, and rubbers. PT is a cost effective approach to rapidly inspect large objects or a high quantity of items.

ATS is capable of detecting common and uncommon discontinuities open to the materials surface. Some of the most common discoveries are fatigue cracks, grinding cracks, overload and impact fractures, and weld discontinuities.
