K2's NDT training classes for Level I and Level II:
Visual Inspection Testing (VT)
Most NDT inspections start with a Visual Inspection. Performed using the human eye, it is the most common and readily available inspection. Often, the inspector is trained to look for certain clues that might indicate defects or flaws.
Liquid Penetrant Testing (PT)
Liquid Penetrant Testing, which is also known as dye penetrant testing (DPI) or liquid penetrant inspection (LPI), is one of the most cost effective NDT methods for testing non-ferrous material.
It locates surface defects in non-porous material when you apply a fluorescent or non-fluorescent dye penetrant to the surface. This method can detect cracks, fatigue cracks, forging and casting defects
Magnetic Particle Testing (MT)
This common NDT method is capable of detecting surface and sub-surface defects in ferrous materials.
It involves the induction of a magnetic field to or around the test specimen. If the material has a surface or near-surface flaw, it will create a magnetic flux which will attract small magnetic particles to the flaw area, making it detectable.
Ultrasonic Testing (UT)
Ultrasonic Testing takes place when a short ultrasonic pulse-wave is sent into a material to detect internal flaws or identify different types of material. This method is also commonly used to determine the thickness of material. UT testing can be used on alloys, steel, concrete, wood and composites.
Radiographic Testing (RT)
This NDT inspection method uses electromagnetic radiation wavelengths to penetrate various materials to detect flaws. This x-ray detection can be used on lead and steel to detect external and internal flaws, but cannot be used on plastic.
Radiation safety is very important when using this testing method due to possible exposure to strong gamma sources in remote sites.
Eddy Current Testing (ET)
Eddy Current Testing uses electromagnet induction in conductive materials to detect flaws. This method can detect very small flaws in or near the surface of the material. Its application is limited to a conductive material where the surface is accessible.
Eddy Current Testing (ET)
Alternating Current Field Measurement Testing (ACFM) is an electromagnetic technique for detecting and sizing surface breaking defects in metals. ACFM is particularly suited for inspecting painted and/or welded structures underwater and in suspected fatigue crack locations.
