Radiographic Inspection

Radiographic Inspection Advantages and Limitation

Education, Mechanical /

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 or Dye Penetrant Inspection

Education, Mechanical /

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

Nondestructive Testing

Nondestructive Testing of Weldment (NDT)

Mechanical /

Nondestructive testing (NDT) is the examination of an object or material with technology that does not affect its future usefulness. It is an approach to testing that involves in evaluating the weld without causing physical damage. The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this

Welding Processes used in Aeronautical Industry

Mechanical /

Friction Welding (FRW) – Welding Processes used in Aeronautical Industry In this process (Welding Processes used in Aeronautical Industry), joining of the metals is achieved through mechanical deformation. Since there is no melting, defects associated with melting-solidification phenomena are not present and unions as strong as the base material can be made. This process can
