Integration Between Artificial Neural Networks And Responses Surfaces Methodology For Modeling Of Friction Stir Welding

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

In stainless steel industry, TIG welding has an important role on joining thin sheets, tubes and pipes. Depending on this important role, the mechanical behaviours of TIG welded joints

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.

Even though the probability of failure of stub axle is higher due to impact failure of weld joints. Which may cause the serious safety effect.

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.

the next thing you need is to use the right technique. with the right use of the right technique you can reduce most all the distortion in the weld. distortion is the under cut, porosity the wrong doing of the bead. if you have distortion you have a weld that is no good. the z weave technique is where you move the rod side to side and pause 2 seconds at the corners of the weld. there is also the stringer bead where you move in small tight circles in the direction of your weld. both techniques are good it all depends on the welder those are the two biggest techniques used on the pipeline. after you learn all this your training will be sufficient the next thing you need to do is go get your certifications.

The skills needed for welding are a steady hand for clean weldings, a stable head for welding in difficult or stressful positions, you need to be able to do at least basic math, also endurance, and problem solving.

Anything that's not bolted together is probably welded. Cars, planes, bikes, buildings, computers, medical devices, and even amusement park rides require welders to cut, assemble, and join all kinds of materials, including nonmetallic ones. Plastics and composites, for example, can be welded using high frequency vibration. The method is called ultrasonic welding, and it's one of many high tech subspecialties available in a field that needs workers badly. A shortage of 250,000 welding professionals is expected by 2010, according to the U.S. Department of Labor. Not enough new people are entering the field to replace retiring welders. Trained welders entering the field are likely to find good jobs. Welding can be learned in high school industrial arts programs, trade schools, and community colleges. The programs run from a couple of weeks to two-year associate degree programs. To prepare for the field, students should take drafting and as much math as

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).

Explosion welding is unique, because it is the only kind of welding that can join any metal together into a single piece known as clad. Two metals are placed together with an explosive powder in between. When designated about 2 million pounds of downward force join the two pieces together. Originated in World War I and II, after strap metal became welded onto pieces armor.

College, pay rate, and the long topics of availability. These are things common people know you will need, so why not actually learn about welding. Here are some basics and simple elements used in welding. “Shielded Metal Arc Welding” (SMAW) – Shielded Metal Arc Welding is also known as “SMAW” or as “stick welding.” The stick in question refers to the electrode, which is coated in a protectant flux. An electrode holder holds the “stick” in place and an electric arc is created using either direct or alternating

Being a welder is not just a job, it’s a life style dedicated to the many things they do. “Welders use hand held or remotely controlled equipment to join or cut metal parts. They also fill holes, indentations or seams in metal products” (BLS.Gov). Basically, welding is a job for an individual to cut metal to the size needed whether by hand or electronic equipment. After the metal is cut, it is properly welded where it needs to be based on what the blueprint says. “Welding is the most common way of permanently joining metal parts. In this process, heat is applied to metal pieces, melting and fusing them to form a permanent bond.” (BLS.Gov) In other words, welding is just a way of putting metal together just like gluing paper.

The first process examined uses the Lablond Lathe machinery and requires a machined diameter of 7.7250, plus tight tolerances of + .0005 inches. A Process Capability Ratio (Cpk) analysis of the lathe’s data, results in a Cpk of .379 (exhibit A). A result of less than one indicates the machine is not capable of matching the tolerances laid out in the IMS spec. Therefore the Lablond Lathe is not suitable to handle the process it is being used for. Before a more suitable machine is selected, the Lablond Lathe should be checked for calibration, as should the measuring equipment used. If all fall within calibration specs, new

110v machines are basically for starters, they don't provide a lot of working time like a 220v would. “ TIG welding produces a small arc, and this makes it perfect for welding high-heat conductivity materials like aluminum. TIG was created to weld dissimilar metals” (Page 1). This process was made to weld high-heat conductivity metals like aluminum and dissimilar metals like Stainless Steel and Aluminum. TIG welding is most commonly used to weld thin sections of alloy steel, stainless steel and non-ferrous metals such as aluminum, magnesium, and copper alloys. The process grants the operator greater control over the weld than other welding processes, allowing for stronger, higher quality welds. TIG welding is more complex and difficult to master than other welding types, and is slower than other types.
