Ultrasonic Inspection This method is used to find internal defects by using ultrasonic inspection sound waves. Very minute defects such as cracks, porosity, blowholes etc. can be accurately detected in castings. Sound waves can pass through solids without any absorption. It can also be reflected from a surface. Hence, ultrasonic waves are used in this

Radiographic Inspection Radiography (X-ray) is an NDT method used to radiographic inspection material and components using the concept of differential adsorption of penetrating radiation. Each specimen under evaluation will have differences in density, thickness, shapes, sizes or absorption characteristics. Thus, the different amount of radiation is absorbed. The unabsorbed radiation that passes through the part

Liquid Penetrant Inspection Liquid penetrant inspection is used on nonporous metal and nonmetal components to find material discontinuities that are open to the surface and may not be evident to normal visual inspection. The dye penetrant method is frequently used for the detection of surface breaking flaws in non-ferromagnetic materials. The basic purpose of penetrant
