other hand , the first curve is for annealed steel, where the yield point can be defined and it's the level at which the curve of stress-strain curve becomes horizontal. The yield strength is improved due to the influence of cold formed of steel ( cold work done into strain-hardening range ).Cold formed steel has a yield stress value in rage of 33 Ksi and 80 Ksi, and the values of Modulus of Elasticity ( E ) are approximately 30,000 ksi ( 207 GPa ), these values are considered in the design…

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…

made just for welding. Today sir humphreys tool has been modified and made into as we know today as the arc welder. Welding is more of an art than a job because you start with a pile of scrap metal and after hours of thinking and just a little bit of work you end up with a beautiful piece of art. (”http://www.gowelding.org/articles/history-of-welding/) there is over 800 jobs welding anything from cars, planes, and boats to skyscrapers. there is 30 jobs…

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…

brass, bronze, and even gold. GTAW can also weld dissimilar metals to one another such as copper to brass and stainless to mild steel. 1.3.1.2 Concentrated Arc The concentrated nature of the GTAW arc permits pin point control of heat input to the work-piece resulting in a narrow heat-affected zone. A high concentration of heat at point is an advantage when welding metals with high heat conductivity such as aluminum and copper. A narrow heat-affected zone is an advantage because this is where the…

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.…
