Pin and Button Locators This is one of the common methods of pin locating. A round pin or button is used to support the job firmly and holds it in position.  The main difference between pins and buttons is in length.  Buttons are generally shorter...

WELDABILITY OF STAINLESS STEELS The most popular welding process used on Stainless Steel Weldability is Gas Tungsten Arc Welding (GTAW or TIG).  It is the most widely used process due to its versatility, high quality and aesthetic appearance of the finished weld.  Pure argon is...

WELDED JOINTS Welded joints are classified according to the relative positions of two components to be joined.  There are five basic welded joints types. Butt joints:      It is used to join the ends or edges of two plates.  The surfaces of plates are located in...

WDM - Wavelength Division Multiplexing A distinctive operational feature of an (WDM wavelength division multiplexing) optical fiber is that there is a wide spectral region in which optical signals can be transmitted efficiently.  For full- spectrum fibers this region includes the O-band through the L-band,...

UNDERWATER WELDING PROCESS Underwater welding process usually refers to the wet welding technique where there is no mechanical barrier that separates the welding are from water.  It is also known as submerged water arc welding.  For deep water welds and other applications where high strength...

INTRODUCTION TO DESIGN USING COMPENSATORS - Linear System Design The control systems are designed to perform specific tasks in linear system design. The requirements of a control system are usually specified as performance specifications. The specifications are generally related to accuracy, relative stability and speed...

Optical Receiver Operation Having discussed the characteristics and operation of photodetectors in the previous chapter, we now turn our attention to the optical receiver operation. An optical receiver consists of a photodetector, an amplifier, and signal-processing circuitry.  The receiver has the task of first converting...

INTROCDUCTION to THERMAL ENERGY BASED PROCESSES      In these methods, Thermal energy based process heat energy is concentrated on a small area of the workpiece to melt and vaporize the tiny bits of work material.  The required shape is obtained by the continued repetition of...

HYDRAULICS SYATEM The Hydraulics system of interest to control engineers may be classified into, Liquid Level system and Hydraulics devices The liquid level system consists of storage tanks and connecting pipes. The variables to be controlled are liquid height in tanks and flow rate in pipes....

Introduction Chemical Machining Process (CHM) In chemical energy methods, Chemical Machining Process the metal is removed from the workpiece through controlled etching of the workpiece material in contact with a chemical solution. Example: Chemical Matching (CHM) In Electro-chemical energy methods, material is removed by ion displacement of...
