Bend test is one of the commonly used destructive tests to determine the ductility and soundness (for the presence porosity, inclusion, penetration and other macro size internal weld discontinuities) of the weld joint produced using under one set of welding conditions. There are following two types of bend test: Free bend test Guided bend test

Mechatronics engineering is a word originated in Japan in 1980s to denote the combination of technologies which go together to produce industrial robots. The word, mechatronics, is composed of “mecha” from mechanism and the “tronics” from electronics. In other words, technologies and developed products will be incorporating electronics more and more into mechanism, intimately and

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

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 the most popular shielding gas but argon rich mixtures with

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
