Aqualified Qualifications

 

Submarine NDI requires special expertise. Our team of inspectors are primarily retired military personnel who have experience in nuclear environments, government, Department of Defense, technical orders, and procedures. Our NAVSEA T9074-AD-GIB-010/1688 and NAVSEA S9074-AR-GIB-010/278 Level II qualified inspectors are prepared for your NDI needs.They are all certified with NAVSEA T9074-AS-GIB-010/271 on a 3 year interval with annual eye exams and a 7 year SS trace. We are also JCP Joint certified for our Canadian friends. Testing methods used NDI Submarine inspections are listed below:

Visual testing is simply stated as looking at a component with your eyes. VT testing can be performed with flashlights, optical prisms, microscopes, comparators, borescopes & video probes.

Liquid penetrant also known as dye penetrant is a fluid usually used to find small openings at the surface of a material that is nonporous.

Magnetic particle inspection is used primarily to detect cracks on ferrous materials.

In the industrial sector record retention of x-rays is just as important as the inspection itself.

Ultrasound (UT) is also called ultrasonics, UT straight beam (longitudinal), UT shear wave, UT immersion testing, UT phased array and UTT for ultrasonic thickness.

Eddy Current (ET) is also called electromagnetic induction and can be broken up into four subgroups: AC Field Measurement, Flux Leakage, Remote Field and Eddy Current.
