Hall effect sensor work is a type of magnetic sensor. A Hall effect sensor is a transducer that varies its output voltage in response to changes in magnetic field. In 1879 Edwin Hall discovered that: ‘when a conductor or...
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...
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...
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...
Principle – Magnetic Particle Inspection Magnetic particle inspection is a method of detecting invisible cracks and other defects in ferromagnetic materials such as iron and steel. It is not applicable to nonmagnetic...
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...
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...
Atomic Hydrogen Welding (AHW) Atomic Hydrogen Welding (AHW) is a combination of electric are and gas welding technique. It is a thermo-chemical arc welding process in which the workpieces are joined by heat obtained on passing a...
Photoelectric sensor A photoelectric sensor is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared or LED, and a photoelectric receiver. Photoelectric sensors...
