NDT methods like ultrasonic testing, radiographic testing, magnetic particle testing and visual inspection are often employed for these tasks without causing any lasting harm to materials or structures being tested.
Ultrasonic testing is used to detect internal defects in materials and components such as cracks, voids, or inclusions by transmitting ultrasonic waves through them and measuring their reflections. It has become an indispensable technique in industries including aerospace, automotive, manufacturing, construction for inspecting metal, plastic composite material welded/bonded joints as well as metal/plastic combinations with joints that need inspection.
Radiographic testing is an efficient method for detecting internal defects such as cracks, voids and inclusions in materials and components by subjecting them to X-rays or gamma rays and recording their images onto film or digital detectors. Radiographic testing has become widespread use across industries including oil and gas, nuclear energy and aerospace for inspecting welds, castings, forgings and composite materials.
Magnetic particle testing is used to detect surface and near-surface defects such as cracks, laps, and seams in ferrous materials and components by applying a magnetic field and magnetic particles onto their surfaces. It has wide use across industries such as automotive manufacturing and construction for inspecting steel, iron and other ferrous materials.
Visual inspection is used to detect surface defects in materials and components by visually inspecting them using light sources, magnifying glasses, or borescopes. Visual inspection has become popularly utilized across industries including construction, manufacturing and aerospace in order to inspect welds, coatings and assemblies.
Other Nondestructive Testing (NDT) methods, including eddy current testing, dye penetrant testing, acoustic emission testing and thermal imaging are widely employed across industries for inspecting materials, products and structures. These non-destructive methods offer non-destructive yet reliable ways of detecting defects as well as flaws within critical components while upholding quality, safety and reliability standards of materials and structures.
