Liquid Penetrant Testing (PT) is one of the most common yet effective techniques detecting surface defects on wide range of materials and welds where the properties of the material limit the use of other NDT methods. PT is an effective means of locating and determining the severity of surface discontinuities in materials, including those that are not visible to the naked eye.

The process behind LP involves the application of penetrant on a tested asset, where it is allowed to dwell or soak for a determined amount of time. Once the part has had ample time for the penetrant to dwell it is removed carefully, and the developer is applied. The penetrant bleeds through the developer, which produces a visible or fluorescent indication that we evaluate to applicable codes, standards, and client specifications.
