The And Mechanical Properties Of Dissimilar Aluminium Alloys By Friction Stir Welding

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.

Tungsten inert gas (TIG) welding is the process of blending together reactive metals such as magnesium and aluminum. The TIG welding method became popular and useful in the early 1940s and, as a result, has greatly propelled the use of aluminum for welding and structural processes. TIG welding is commonly used for both high quality and manual welding.

Welding dates back to ancient times! The early examples come from the bronze age when they used pressure welding to hold to gather small gold boxes. Pressure welding is used when two pieces of metal are heated up and pressed together and then rapidly cooled then the joints form together. This process is also known as forge welding and it was

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.

There is even a type of welding for high pressure fuel lines that have broken and are spraying fuel, it involves bathing the area of weld in nitrogen.

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

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.

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.

The history of welding has traveled from all around the world and has improved so much.Welding has believe to have started from 4000 B.C. and is still going on right now.

The advances in welding have also made advances in chemistry. This means that they go hand-in-hand with each other. The more you understand one, more you can understand the

Arc welding utilizes an electric current which flows between an electrode and the welding material to melt the metal and make the weld. The

In the process analysis of resistance spot welding on galvanized steel used in vehicle body manufacturing, the quality of spot weld is checked from the tensile strength and shear strength properties of the spot weld. The four important parameters in this analysis are:

GMAW( Gas Metal Arc Welding) is a process that produces high productivity.Kodi Welch indicates that “ GMAW offers high productivity; the ability to weld on thin and thick metals; to help reduce weld defects, and the process can be used in all positions” ( Page 1). GMAW is very productive, and thats why its used in many applications. It is also used to weld in all positions, you can weld on your knees, or standing up etc. Doityourself believes that“ MIG welding is simple to use and it is efficient. It requires attention to safety as well as attention to the process that makes the
