Welding - Introduction and Types

Welding – Introduction and Types

Life is made of ever so many partings welded together. -Charles Dickens Welding is a metal joining process that is used for joining two or more similar metallic workpieces (or thermoplastics) by the application of heat. It finds its application in a large number of industrial processes. Welding can be done either by melting and solidifying [...]

Tungsten Inert Gas Welding (TIG Welding)

Tungsten Inert Gas Welding (TIG Welding)

Tungsten Inert Gas Welding (TIG Welding), also known as Gas Tungsten Arc Welding (GTAW), is an arc welding method that uses a non-consumable tungsten electrode to weld two or more workpieces. It is very much similar to Metal Inert Gas (MIG) Welding. Diagram of Tungsten Inert Gas Welding: Components used in Tungsten Inert Gas Welding [...]

Metal Inert Gas Welding (MIG Welding)

Metal Inert Gas Welding (MIG Welding)

Metal Inert Gas (MIG) Welding (also known as Gas Metal Arc Welding [GMAW]) is an arc welding technique in which a consumable electrode is used to weld two or more workpieces. A diagrammatic representation of metal inert gas welding is shown below: Components used in Metal Inert Gas Welding (MIG Welding): Metal Inert Gas Welding [...]

Generalized Measurement System

Generalized Measurement System

Several measurement systems are in use today. Before measuring a physical quantity, it is necessary to understand the working of the measurement system used. Generalized measurement system is a system that is comprised of the typical elements of a measurement system. It helps to understand how a measurement system works. Block diagram of generalized measurement [...]

Derivation of mean effective pressure of Otto cycle

Derivation of mean effective pressure of Otto cycle

In my previous articles, I gave an introduction to Otto cycle and derived the air-standard efficiency of Otto cycle. In this article, I will derive the mean effective pressure (m.e.p) of Otto cycle. What is Mean Effective Pressure? Mean effective pressure is the ratio of work done (W) during the working stroke(s) of a cycle [...]
