Friction Stir Welding Essay

It was hard to weld back in those times, but throughout time and progression welding became more of a phenom for the building of metal surfaces and structures. The American Welding Society (AWS) was founded in 1919, it was formed to advance the technology and science of welding. It put more detail and analysis on how to form the welds, how to control the weld puddle, The distance of the arc length from the electrode and the work piece. Welding is a special trade, it takes a person to have good near and far sight, steady arm and hand motion, and concentration. Welding has become great for a lot of amazing things like building automobiles, building structures, bridges. Their have been a lot of things that welding can be attributed to and is amazing for

Welding is a process used to join metal parts by producing a coalescence, called a weld, at a joint. Advances in welding technology have opened the way for innovative designs in structures and machinery. Of modern welding processes, the greatest number fall under the general classifications of arc welding, gas welding and cutting, resistance welding, and brazing.

Since its development in the middle of the 20th century, MIG welding has become commonplace in many manufacturing operations. For example, it is commonly used in the automobile industry because of its ability to produce clean welds, and the fact that it welds metals quickly.

Going on a few centuries to the 1890s C.L. Coffin a man from Detroit was credited the U.S. patent for the metal electrode. This was the first recorded passing of melted metal from the electrode through the arc onto the metal forming a weld. This process made the welds stronger than ever holding longer and looking better as well. They proved this point by having two steel beams one that was riveted and bolted vs welded. The put both through extreme bed test and the welded joints held a lot longer and proved there last. This showed the world that welding was a reliable way to join metals. This sparked a fire buildings were allowed to have more joints and curves opening up a new design for houses and commercial buildings. After this new styles were showed the demands for welding machines went through the roof and the needs for welders as well.

Usually bond two dissimilar metals are joined using this process of welding, especially to weld one metal over a base metal extending to large areas. Production of corrosion free sheets and plate stock for making processing equipment for different operations in the chemical industries and petroleum industries are the major applications. Explosion welding general requires no filling metals, and external agencies for production of heat are also not required. Diffusion does not occur during the processes. The metal parts are metallurgically bonded, in many cases it results in a mechanical interlocking that is occurred as locking formed by a rippled or wavy interfaces between the surface of metals. The process of welding one metal plate on another can be described with help of Figure

Welding is the process of joining pieces of metal or other parts by heating the surfaces to the point of melting using a blow torch, electric arc, or other means. This careers demand has skyrocketed in recent years. According to Tri-County Technical College, welding is ranked as one of the top ten fastest growing career fields in South Carolina by the US Department of Labor (“Welding Associate's Degree”). Welding is a very meticulous career, to be a welder you have to be focused, careful and you have to have an extensive knowledge of the field to be successful. Welding requires a variety of skill sets. If a person has a variety of skills and experience doors will open up for positions such as: shipbuilding, automotive repair, and construction.

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.

Welding must be done carefully to avoid contamination and machining must be done precisely. Titanium is very reactive to atmospheric gases and can result in degradation in the material. Titanium is weldable in annealing conditions but provide limited weld ductility and heat affected zone ductility. It can also be significantly strengthened by cold working.

The different gases produce a different weld because of the way the electricity flows through the arc contacting the base metal

Welding is evolving. It is adjusting, dynamic, and testing. It applies new information and logical standards, and it continually is growing its wildernesses.

If you want to be a welder, and actually have a career, you can go to a welding school and learn how to weld, or you can try to be a welders helper and just learn the trade. Welding can be a tough job if you don’t know what you are doing or you do not enjoy doing it. Welding is a fabrication or sculptural process that joins materials together (Modern Welding). This is the process that uses fuel gases and oxygen to make a molten pool of metal to fuse together two pieces of metal, called puddeling (oxy-fuel welding and cutting. Wikipedia). If you decide to weld as your profession, most welding school students have little trouble finding jobs and finding people certified to weld correctly (Welding.Wikipedia).

In most welding you will need to know how to study blueprints, sketches, or specification calculates. Welding is the best way of permanently joining metal parts because welding is used in building ships, buildings, and cars. Welding is good for repair because the welds will not come apart unless you cut it with a torch. Welding also is used to join steel beams in the construction of buildings, bridges, and other structures and to join pipes in pipelines. The work that welders do and the equipment they use all come from the company they work with.

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

The tensile strength, the percentage of elongation and hardness of weld joints were predicted by taking the parameters Tool rotation speed, material thickness and travel speed as a function. A comparison was made between measured and predicted data. Response surface methodology (RSM) also developed and the values obtained for the response Tensile strengths, the percentage of elongation and hardness are compared with
