Basic Welding 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 it.” (Bowditch, Bowditch and Bowditch 259). Oxyfuel gas welding is commonly referred to as “flame cutting” because the flame of the oxygen and acetylene melts the metal enough to cut it. The ignition temperature of steel is 1500 Fahrenheit, which is definitely something to think about before playing with a cutting torch. After lighting the cutting torch, the oxygen and gas must be adjusted until a neutral flame appears, then the metal to be cut …show more content…
The tungsten electrode does not melt or become part of the weld. Therefore it is considered a nonconsumable electrode.” (Bowditch, Bowditch and Bowditch 163). Gas tungsten arc welding is often referred to as TIG welding, which means tungsten inert gas welding. This is slang for the actual name to be used, because the gas (argon) that is used is not an inert gas. Tig welding is the cleanest welding process of all, because there are not many undesirable byproducts. However, tig welding is still a very dangerous process, just like any other welding process. Many other welding processes rely on heat alone to transfer metal, which causes fumes and undesirable spatter. Gas tungsten arc welding uses electricity to transfer heat from the electrode to the base metal, which causes less fumes and no spatter, so that means not having to worry about nasty little burn marks on the
There is a type of welding that utilizes hydrogen, called Atomic Hydrogen Welding. The welding tool is two tungsten steel rods, acting as electrodes, through which passes an arc of electricity. Hydrogen gas is pump through the arc, and the temperature of the arc disassociates the gas into individual molecules, which absorb an incredible amount of heat. When the gas passes through the arc, it reassembles itself, and burns ordinarily, and using oxygen in the air. This is the hottest type of welding process yet; with a flame of over 7232 degrees F. it was invented in 1926, and was used extensively in Germany during WWII.
Plasma cutting is a method of cutting through metals by means of an accelerated jet of hot plasma, using a plasma torch. It is a process that is extremely essential for the shaping of metals through cutting away unwanted parts.
Welding is a dangerous job because you can hurt your eyes from the flash if you don’t wear eye protection. Yes pipeline welding dangerous, but it is wrong because it is only dangerous when proper safety precautions aren’t taking place. Welding is dangerous because pieces of metal can fall on you and you can get flash burn. And you can be exposed to gases, fires, explosions, and electric shock. But the only way these things happen is when safety measures are ignored.
Welding is a very important job in today’s society. With new building designs, and bridges to every day metal products, welders are needed to do these tasks. Almost everything that you use every day has some sort of weld to it.
Scuba diving itself can be challenging at times. Imagine having a difficult task, like welding, to perform at the same time as scuba diving. This is a task that can cost you your life if not done correctly and as safely as possible.
To begin with, Study.com tells that the lowest level of education required is a high school diploma or equivalent. Many employers may require an employer- based welding test. Some employers look for a certificate or undergraduate degree from a technical school (Study.com). Next, it is important to note where training is available. WATC.edu states, that they offer a welding program. WATC is located in Wichita Kansas. Their welding program allows students to gain knowledge and skills in cutting, shielded metal arc welding, gas metal arc welding, gas tungsten arc welding, and provides some exposure to oxy-acetylene cutting and welding (WATC.edu). In addition, the length and cost of the training is an important consideration. WATC.edu shares, that there are 5 different degree and certificate options. The one I would be interested in is the Welding Technical Certificate option. This one would be a total of 46 credit hours and would cost a total of $10,524. Finally, this job requires certain traits, talents and interests. The Occupational Handbook adds, that welders often must work in awkward positions using tools, so they need to be able to put up with that. A lot of times, overtime will be present. So you would have to be available for overtime if needed. Welders are required to lift heavy objects sometimes. So a welder should be fairly strong (The OCO). I think that being a welder would be hard work. I feel that I would be able to work hard enough to be a welder. I now know what traits a person should have, in order to be a welder. In summary, there are educational and personal qualifications to consider if I want to become a
Welders can use hand held welders or even robotic welders to produce welds. Both equally requiring a incredible amount of knowledge. They can also fill holes, produce structures and build custom parts for automotive race shops. Welders often work fulltime on shipyards, oil rigs, and pipelines or anywhere else where a specific job is needed. Welders are often required to interpret blueprints or sketches and weld accordingly to fulfill job duties. Arc welding is the most common type of welding today and is what most welders use. (bls) There are over 100 different welding processes that a welder can learn how to use however, Stick, Tig and Mig are the 3 most common used in the industry. These are used most to maintain equipment
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 was from the bronze age when metal boxes were made by “pressure welding lap joints together.” In medieval times welding was used by hammer to forge weapons of different types. “It was actually not until the late 1800’s that traditional welding
The recruiter told me Tig welding would be the best choice for me but I don’t know if I’m sure on that. I did a little research on pipe line welding but I couldn’t find too much of noting on the website I was on. The recruiter also told me Tig welding will be the hardest and take the longest to learn. I aren’t even tripping about that though because I know that in order for me to succeed something have to be hard alone the way, nothing comes easy for nobody.
When oxy cutting, you must switch tips before starting. This from of cutting happens when you use the torch to heat the metal to its extreme temperature. stream of oxygen is then pushed upon the metal, burning it into a metal oxide to cut through the metal. The torches used do not mix oxygen and fuel together they instead go through two different hoses to then come out through the tip. Combined syetems of single tanks are not oxy fuel torches, when can be recognized because oxy torches have two tanks others like just acetylene torches used in brazing and soldering is a single tank, which is suitable and works well for that type of work but not for welding. The uses for oxy- gas torches would be welding metals, cutting metals, stone working in jewellery production for “water welding”, auto mechanic repairs to remove seized bolts
Welding is a very important tool used in our daily lives. Welding is the process of joining two metal pieces together by applying heat. A filler helps to make the joint. Everything we use from trucks to houses have some type of welding in them. There are many types of welding careers to choose from. There is a great demand for welders today. My project was to build a table and candelabra out of metal. Most of the metal I gathered came from junk yards and had to be cleaned of rust.
In past few years, companies and industries of various sizes have become aware that they need to improve business processes such as product development, order fulfilment, planning, distribution, and customer service. So everybody is now focusing on doing process improvement or redesigning.
Welding is an art, science, and high paying career all in one. Welding is the most effective way to join two pieces of metal, it is the only way to join them so they act as one. Numerous things in our daily lives has been welded from coffeepots to skyscrapers. Welding can be done almost anywhere outdoors, indoors, underwater, and even space (“Welding Basics”). It is practically
T.I.G ( Tungsten Inert Gas) is a challenging process to learn. Jonathan Atteberry claims that “ T.I.G welding is difficult to learn and requires an elaborate welding rig of skills. It also uses a lot of electricity to make the welds clean and spatter less” (Parag 5). T.I.G welding is hard to learn because of people having different hand coordination. Most people would expect a long time to weld TIG because it is hard and requires a lot...
