TIG Welding Essay example - 1469 Words

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 one of the arc welding methods. This method is suitable for many kinds of metals, but especially for welding of stainless steels, aluminum and magnesium. 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†¦show more content†¦An inert shielding gas is used in the process at no applied pressure. Argon is most commonly used as the shielding gas, and the process may be employed with or without the addition of filler metal. Helium, carbon dioxide and hydrogen (mixed with argon) are other main examples of shielding gases for TIG welding. TIG is widely used for thinner sections. Its extremely suited to join thin sheets, tubes and making root pass welding in pipes, since the heat input in this process is minimal. Advantages of TIG Welding include its versatility, low equipment costs, control, and weld quality. It is widely used for the welding of light gauge stainless steel and aluminum and root passes in pipe butt joints. The TIG process can easily be set up as an automated process. Another positive attribute of TIG Welding is the very low fume formation rate (FFR). The filler wire is fed and melted into the weld pool allowing a lower FFR. This procedure is different from other processes that require the fill material to pass through the arc. Since filler is fed directly to the weld pool, operating variables have little effect on the FFR. The sometimes over looked disadvantages of TIG Welding are its low speed and deposition rate which utilizes hot or cold wire feed and high heat input efficiency. By using shielding gas, these problems can be overcome. The TIG weld zone is also difficultShow MoreRelatedThree Basic Welding Methods736 Words   |  3 Pagesbasic welding methods. How could they improve their career? The three basic welding methods are TIG(Tungsten Inert Gas.) MIG(Metal Inert Gas.) And SMAW(Shielded Metal Arc Welding.) If the welder had more knowledge about the welding methods, then they could figure out which of the three can produce the most welds in a certain amount of time. TIG welding is the best, and most efficient because it can deliver more welds in a day, and reduces the cost of sales. The welding trade has new TIG welding machinesRead MoreThe Field Of Welding Technology1631 Words   |  7 PagesThe field of welding technology is one of considerably low requirements on the education spectrum while incredibly demanding on the spectrum of general know-how. Welding professionally can be seen as an easy way out for some but a profitable career for others. The typical stereotype often is true, that welders are less educated traditionally, but it does not mean that what they do is non-important. As a matter of fact, a career in welding can put you in NASA.

The MIG artisan conjointly uses an outsized spool of wire for the conductor rather than a welding rod to form the weld and is usually used for objects that require a smaller more precise weld or a stronger weld. The MIG artisan is that the best to use and learn out of all the opposite welders. The TIG artisan is often used for skinny metal that reacts to higher temperatures like metal.

Metal Inert Gas (MIG) welding, also sometimes called Gas Metal Arc Welding (GMAW) is a process that was developed in the 1940s for welding aluminum and other non-ferrous metals. MIG welding is an automatic or semi-automatic process in which a wire connected to a source of direct current acts as an electrode to join two pieces of metal as it is continuously passed through a welding gun. A flow of an inert gas, originally argon, is also passed through the welding gun at the sameRead MoreWelding Research Paper1394 Words   |  6 Pages GMAW (Gas Metal Arc Welding) is more economic; Springer reports that â€Å" 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 ran ge of work, but it is not suited for repair work because ofRead MoreMajor Hazards Associated With Manual Arc Welding1927 Words   |  8 PagesP1a List and describe in detail, (with illustrations where appropriate) 5 major hazards associated with manual arc welding.
