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 weld quality” (Page 4). This process can be used for many variations of work including root welds, joints, T’s, butts, laps, and many more applications. Even though its used for many practices, it is not recommended to use this method for repair work because of the quality of the welds. “ It’s easy to use and it is inexpensive to afford now with 110v machines. But you cannot weld for a long time like a 220v machines would produce. Both have different duty cycles” (Parag. 7). M.I.G is something anyone can learn easily, it’s inexpensive to afford. 110v machines don't bring out the best power to weld, because these machines do not have a good duty cycle. Most people prefer 220v machines because they produce more work, even if they are more expensive. GMAW is the cheapest most reliable process for welding.
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...

scientific experiments (Go welding: history of welding 1). Conventional welding is most easily explained as arc welding processes. Some arc welding processes are TIG welding, Stick Welding(SMAW), and MIG welding. TIG stands for Tungsten Inert Gas welding this means that using tungsten as a electrode and an inert gas, which is usually argon, the weld is produced by creating an arc between the piece being welded and the tungsten electrode. SMAW or stick welding utilizes a stick electrode held in a clamp surrounded by a powdered substance to weld. Mig welding uses a machine that holds a wire feeder within it, the wire feeder feeds the wire electrode through a tube to a gun that slowly sends out the wire as well as a steady flow of inert gas. These and other processes classified as conventional welding processes are the best processes for welding jobs because they are more cost effective, more...
Friction stir welding is a solid state welding process; this remarkable up-gradation of friction welding was invented in 1991 in The Welding Institute [1]. Figure 1 shows the schematic representation of the Friction Stir Welding process. The process starts with clamping the plates to be welded to a backing plate, so that the plates do not fly away during the welding process. A rotating wear resistant tool is plunged on the interface between the plates to a predetermined depth and moved forward in the interface between the plates to form the weld. The external tool has a probe and shoulder which stirs the material to be joined and forges the surface. FSW comes together with forging and extrusion processes. The probe and shoulder extrudes the material by stirring and the shoulder alone forges the material surface to be joined.
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
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.
The first evidence of welding dated all the way back to the bronze age. The first people that found out how to weld were the Egyptians the Egyptians were smart enough to figure out how to weld. In the 19th century they figured out they could use acetylene for welding. A Englishman named Edmund Davy is the one that discovered acetylene in 1836. Then in 1880 Auguste De Meritens figured out how to fuse two lead plates together from the heat generated by an arc. Then in 1890 C.L Coffin discovered carbon arc welding which is one of the most common welding process used in today's world. Then in 1900 is were welding got introduced to a lot more advanced welding such as, seam welding, spot welding, flash butt welding, projection welding, and also electrodes were invented at the same time. A electrode is a piece of metal coated in lime to make the arc much more stable which results in better welding turn out. Then in 1919 CJ Holstag discovered alternating current. Then in 1920 P.O Nobel invented automatic welding which is a big thing in today's world. Then in 1930 New York Navy Yard developed stud welding which is used mainly for the construction industry. Then in the 1960s more welding techniques were developed such as, dualshield welding, innershield welding, and electroslag welding were
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
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.
If I do choose to be a welder, several welding positions do not provide good benefits. I will need to make sure that I can afford healthcare, but also invest and save money to have for retirement. Welding could be a lifelong skill or hobby for me. I could use my abilities to work on my own personal projects at home like rebuilding cars, or I could use them to create or build parts. Possibly invent and build a part or tool to patent and sell, becoming an

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

There is different types of rods and different types of ways to weld. You need a lot of training for it. There are many schools and colleges you can go to receive welding education. The most common welding processes are Gas Metal Arc Welding, Flux Core Arc Welding, Gas Tungsten Arc Welding and Shielded Metal Arc Welding. The easiest of these is the Gas Metal Arc Welding. Welding options are stick, flux core, tig, and mig. The pipeline tig and stick welds a lot more than the other .The pipeline use many types of techniques but, the most common on the pipeline is downhill root pass and the up hill pass. The median annual wage of welders, cutters, solderers, and brazers is
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
