Penetrant and Magnetic-Particle Inspection for Material Integrity

摘要

The Nondestructive Evaluation Section at Lawrence Livermore provides penetrant and magnetic-particle inspection services. These two techniques are used on materials and fabricated parts to test for surface or near-surface cracks and defects that may limit serviceability. The use of these methods assures a trouble-free service life, improves safety, and is cost-effective. The inspection of material at appropriate stages of fabrication can result in real saving of time and effort by detecting potentially unusable material before extensive machining and finishing have been performed.
