Minerals and their derived products are the foundation of many important industries. Mines and quarries can be found in almost every country all around the world. Mining industry products provide most of the needed energy, from electricity in homes and industries, to fuel in cars, machinery and tools Resources obtained from mines are also used as inputs for raw materials, consumer goods as well as for almost all services and processes provided by other industries, such as: manufacturing…

that had come before. Industrialism contributed to the growth of cities and railroads across the nation. One of the most important developments was the revolutionizing of iron and steel. The steel industry emerged around western Pennsylvania and eastern Ohio due to the fact that coal, which is used to fuel the furnaces, and iron, which is made into steel using a variety of methods, were found in abundance in that area. Pittsburg, P.A. became one of the centers of the steel world. New Jersey…

for the aluminum base. The adjustment knobs are based on thousandths. When it is time to break down each machine ,the stick machine uses a flux based rod. The flux is made of a carbon based compound. The welding rods can vary from brass, copper, cast iron, and stainless steel. All of these rods are made for a different type of…

Find out what you need to know about welding safety to get the job done One of the most significant dangers while welding is exposure to arc rays, known as arc flash. Arc flash is a burn off the outer layer of the eye. It’s because of intense exposure to UV radiation from electric welding arcs. It’s mainly like a sunburn, most useful in your eye. There are some approaches to protect yourself from arc flash. You’ll want the right defensive eyewear, which includes protection glasses and a…

On the site visit from 7th October there were many materials that were playing an important part in the development of the roadworks, including steel, concrete/cement and many more. Below I have selected three materials from the site visit and identified properties and uses. • Steel There are over 3000 different grades of steel all with unique physical and chemical properties. The production of steel is made in accordance with its application. Due to its high strength Steel is one of the most…

achieve the chemical reaction of Oxygen and Iron. Hypothesis: Independent Variables Dependent Variables Controlled Variables • Iron wool ball – When it is dipped in various types of liquid it may react to the oxygen in the liquid and chemical changes happen eg: Colour change = rusting • Thermometer – predicting the temperature of the iron wool ball below the room temperature • No substances or variable be kept the same If the off chance that the Iron wool ball is plunged in various…

1.2 Types of welding There are so many types of welding process to weld metal or non-metals are given below. Welding is generally two types: (i) Conventional (ii) Nonconventional 1.2.1. Conventional welding Arc welding (i) Shielded metal arc welding (SMAW), (ii) Gas metal arc welding (GMAW), (iii) Flux cored arc welding (FCAW), (iv)Gas tungsten arc welding (GTAW) or tungsten inert gas (TIG) welding (v) Submerged arc welding (SAW), (vi) Plasma Arc Welding, (vii) Carbon arc welding, (viii) Atomic…

Steel plate has become widely used in the construction and manufacturing industries, and projects cannot exist without it. What many people fail to realize is how not all steel plate has been created equal. In fact, a lot of steel plate grades have unique traits that will make them better for more specific applications. For example, structural steel grade A514 T-1 has been designed so that it has been heat treated. That means that you have higher strength capabilities, and it will weld better.…

hen you transfigure a source object into something else, you are changing the very structure of that object. At a microscopic level, the molecules (as Muggle scientists have named them) twist and distort and become different. For instance, if you are to transform a matchstick into a needle, the molecules of the matchstick will stretch and twist and transform into the molecules of the needle. When you look at the transfiguration with your human eyes, you will only see the matchstick changing into…
