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 in length than pins and are generally used for vertical

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 is necessary, dry water welding is most commonly used. It

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 this process. Example: Electron Beam Machining (EBM) Laser Beam Machining

Solid state welding is a group of welding processes which produces coalescence at temperature below the melting point of base materials being welded without the addition of brazing filler metal. Metallurgical bond is created without melting the base metals. In this welding, heat may or may not be applied. These processes are sometimes called solid

What is Resistance Welding In ancient times, metal welding was done in the form of forge resistance welding (metals heated up to melting point are pressed together) and brazing (weld using alloy of low melting point). FUNDAMENTALS OF RESISTANCE WELDING Resistance welding processes are pressure welding processes in which heavy current is passed for short
