NDT is particularly more effective in testing continuities or mapping material characteristics as compared to destructive test which is usually done on a limited number of sampling test. Today modern nondestructive tests are used in different field such as construction, manufacturing, fabrication and in-service inspections for different purposes such as product integrity & uniformity, mapping of materials, localization of defects, health and quality of structures.[/vc_column_text][vc_custom_heading text=”NDT Test Methods” font_container=”tag:h2|text_align:left|color:%23000000″ use_theme_fonts=”yes” font_weight=”400″ text_transform=”none” sub_heading_character_color=”rgba(0,0,0,0.4)”][vc_column_text]Test method names often refer to the type of penetrating medium or the equipment used to perform that test. The increasing popular NDT method are mainly Ground Penetrating Radar (GPR) and Ultrasonic Testing (UT). One being sensitive towards metallic objects and another for voids due to the nature of the emitting source.
There are others NDT methods being developed for different usage including:
- Acoustic Emission Testing (AE),
- Electromagnetic Testing (ET),
- Guided Wave Testing (GW),
- Laser Testing Methods (LM),
- Leak Testing (LT),
- Magnetic Flux Leakage (MFL),
- Microwave Testing, Liquid Penetrant Testing (PT),
- Magnetic Particle Testing (MT),
- Neutron Radiographic Testing (NR),
- Radiographic Testing (RT),
- Thermal/Infrared Testing (IR),
- Vibration Analysis (VA) and
- Visual Testing (VT).
