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

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 stream of hydrogen through an electric arc struck between two tungsten electrodes. The arc supplies the energy for

Structures for InGaAs To improve the performance of structures for InGaAs APDs, various complex device architectures have been devised. One widely used structure is the separate-absorption-and-multiplication (SAM) APD configuration. Image shows, this structure uses different materials in the absorption and multiplication regions, with each region being optimized for a particular function. Here, light enters the

A power system is said to be well designed if it gives a good quality of reliable supply. Voltage level maintained within reasonable limits is referred as good quality. If reactive power and voltage control variation is more than specified value, the performance of equipment suffers and also the life of equipment is sacrificed. When

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 respond to the presence of all types of objects, be it larger, small, transparent or opaque, shiny or dull, static or

Nature and Definition of Tort The word tort has been derived from the Latin term ‘tortum’, which means ‘to twist’. Thus, Nature and definition of tort means “a conduct which is not straight or lawful, but, on the other hand, twisted, crooked or unlawful.” It is equivalent to the English term ‘wrong’. The Law of

Defects in Welding Process A welding defect is any flaw that compromises, the usefulness of a weldment. The improper welding parameters, base metal and selection of method introduce defects in the weld metal. So, the defective weld causes failure in service conditions and damages to the properties the defects in weld depending on thickness, load,
