Scientific Principles
Penetrant solution is applied to the surface of a precleaned component. The liquid is pulled in to surface breaking defects by capillary action. Excess penetrant material is carefully cleaned from the surface. A developer is applied to pull the trapped penetrant back to the surface where it is spread out and forms an indication. The indication is much easier to see than the actual defect.
Main Uses
Used to locate cracks, porosity and other defects that break the surface of a material and have enough volume to trap and hold the penetrant material. Liquid penetrant testing is used to inspect large areas very efficiently and will work on most nonporous materials.
Main Advantages
- Large surface areas or large volumes of parts/materials can be inspected rapidly and at low cost.
- Parts with complex geometry are routinely inspected.
- Indications are produced directly on surface of the part providing a visual image of the discontinuity.
- Equipment investment is minimal.
Disadvantages
- Detects only surface breaking defects. Surface preparation is critical as contaminants can mask defects.
- Requires a relatively smooth and nonporous surface.
- Post cleaning is necessary to remove chemicals.
- Requires multiple operations under controlled conditions.
- Chemical handling precautions are necessary (toxicity, fire, waste).
Target Audience
Level I: NDT Operators, NDT Salesmen, Anyone seeking the Basic NDT Principles and Practices.
Level II: Engineers & QA/QC Personnel, Welding Supervisors & Inspectors, NDT Technicians & Practitioners, Qualified NDT Level I individuals who want to be qualified as Level II.
Award
Delegates attending and successfully completing both the practical and written assessments will be awarded a certificate showing compliance with SNT – TC – 1A.
