Want to go deep sea diving? Want to go to outer space? Want to travel the world? Anywhere anything is being built, welders are required- and that means just about anywhere you can imagine(Institute For Career Research). Welders build the bones of our society. The welding process creates a stronger jion than just bolts or rivets. What I will be talking about in this paper is explaining the nature of work, the working conditions, what training and education is needed. How much welders make and their
Many people may enjoy the smell of burning metal fumes but i most certainly do not!? This can be one of many problems when one is pipeline welding. I should do welding manufacturing over pipeline welding. Pipeline welding has many more disadvantages than welding manufacturing has on my body, social, and family life. What is welding some may ask. “Welding is the use of brazing or soldering to join together or split apart pieces of metal.” Says miller electric inc. The First recorded forms of welding
Aryan Jones Ms. Ensley and Mrs.Noe World Literature and Composition 31 march 2017 Welding Hello, my name is Aryan Jones and I am a junior at Fannin County High School.I want to be an underwater welder or a “normal” welder. In fact, I actually had an interview with a few welders and they gave me some tips and facts about welding. With this I gained a few skills during my time. In addition, I used to be a Boy Scout, which means I know how to be a team leader and be responsible. Also I have good communication
Welding is a versatile and extremely useful career that is very important in today’s world. The versatile nature of welding allows it to be done either indoors or out and many different places and environments ranging from scaffolding hundreds of feet above a city street as well as deep below the surface of the ocean. A professional welder has the ability to work in an open setting or in a confined space equally well. The ability to weld in any environment and at any time makes an individual an
Everyday metal is being used to create new buildings, pipelines, cars, custom fabrication, and even submarines. Welding is used to bond the metal used in these everyday applications. I chose that I would become a welder because I love to work with my hands and there is something about the whole process of welding and melting metal together to make a finished product that gives me satisfaction. This is a trade and a skill that will be around until there is no metal left on this earth. There are
Gas metal arc welding, or most commonly referred to as MIG welding is a very common and sometimes preferred method of welding. Gas metal arc is personally one of the easiest and controllable welding types there is. Gas metal arc welding was originally made for weld materials such as aluminum, copper, brass, tin and lead. It was also used on steels, but shielding gases were highly expensive in the early 1900s limiting GMAW’s use on steel. It wasn’t till the mid 1900’s for GMAW to really take off
GMAW (Gas Metal Arc Welding) is more economic; Springer reports that “ GMAW is an economic process because it has higher speeds and higher deposition rates than manual arc welding. There is also no need to constantly change electrodes” ( Page 11). GMAW has a higher speed, which means that you can get the job done faster. It also has high deposition rates which makes the weld look clean and smooth.” This method can be used for a high range of work, but it is not suited for repair work because of it’s
Processes Some of the very basic processes of welding include: Gas metal arc welding, shielded metal arc welding, gas tungsten arc welding, and oxyfuel gas cutting. These processes are so unique in certain ways that it is easy to forget about all the dangers that come with welding. When there is a finished weld that is so beautiful from a process that is not really desirable, that is when it is easy to forget. “Oxyfuel gas cutting (OFC) is a process used to cut metal by rapidly oxidizing
including cast iron, steel, nickel and aluminum” (“Welding”). In other welding processes you must use a shielding gas to protect the weld zone from the surrounding atmosphere. When using shielded
because the push-pull gun is about the same size as a regular MIG gun. TIG welding is the next type of welding. TIG stands for Tungsten Inert Gas. TIG is formally known as GTAW (Gas Tungsten Arc Welding) (“Learn how to TIG weld!”). There are three main parts to a TIG welder: the torch, the foot pedal, and the filler rod. The torch houses the Tungsten and the inert gas shield. The foot pedal controls the amperage for better control of the weld, as well as the best amount of penetration into the base metal
Tomorrows Welders Thomas Jefferson said, “I find that the harder I work, the less I call it work”. I have often found myself in situations where I needed to fix something but could not because it is metal. I believe this might be why I began to show interest in welding. There is great satisfaction in being able to create or fix a metal object on your own. As a Certified Welder, I will be able to combine my hardworking drive with my personal interest in metal working to be a successful welder. This
Welding whether its tungsten inert gas, metal inert gas, stick electrode arc, or oxyacetylene torch welding, welding is an incredibly freeing art. Welding allows you to create unlike any other form or sculpting or building process. It is not only an art it is also a building method and is very commonly used in the construction industry to build very strong rigid structures. Welding is the process of melting metals together to form a bond. There are usually three pieces of metal you must fuse to

down hydrogen peroxide because hydrogen peroxide is poisonous and is a product when the liver breaks down waste therefore enzymes (catalase) must be made in order to deal with it. When the enzyme catalase is added to hydrogen peroxide, oxygen gas is

In chemistry there are many renowned scientists. One of the more well-known scientists is John Dalton. He revolutionized the way we view chemistry through his observations and theories. He had many theories that still affect us in the present day. One that stands out in particular is his atomic theory. Without all of his contributions our modern world could not thrive like it is currently. John Dalton from a very young age was intelligent. Born in 1766 Cumberland, England he grew up with his family
Nozzle A nozzle is often a pipe or tube of varying cross sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). Nozzles are frequently used to control the rate of flow, speed, direction, mass, shape, and/or the pressure of the stream that emerges from them. In nozzle velocity of fluid increases on the expense of its pressure energy with decreasing pressure. Nozzle have many types and each of them has special uses. The nozzle types are high velocity, propelling
storage tank, hot oil expansion drum, hot oil circulation pumps and hot oil heater. Hot oil is first circulated by Hot Oil Circulation Pumps (P-1301A/B) through Hot Oil Heater (H-1301) where temperature of hot oil rises to 135°C. Low-pressure (LP) fuel gas is used in burners of hot oil heater. The hot oil outlet temperature of H-1301 is controlled by adjusting heater burner firing. From hot oil heater the hot oil is passed through column reboilers, providing the required heat duty and then back to the
non-linear partial differential equations that describes the spatiotemporal evolution of a fluid (gas). Both equations are derived from conservative principles and they model the behavior of some macroscopic variables namely: mass density, velocity and temperature. The evolution of a fluid (gas) can also be described by the exact dynamics of the individual particles that constitutes the fluid (gas) in terms of Newton equations. However, this is complicated in the sense that in order to compute the
This number can be used to determine the thermal conductivity of gases at high temperature and it also delivers us the information about the thickness of thermal and hydrodynamic boundary layer. 2.5 Reynolds Number In fluid mechanics, the dimensionless quantity, fraction of inertial forces to viscous forces, is known as Reynolds Number. Reynolds number can be shown as ,
