Introduction Welding is a process best described as the method of permanently joining two or more metals. This industry is still growing because of the technologies involved that are always changing. The welding process comprises basic components: a heat source, filter material, a shield, and the metals themselves. Before modern-day welding was developed, two pieces of metals were joined by putting them together and hammering the open ends (History|Reference.com, n. d.). It was called forge welding . After securing the surface, pouring molten metal ensued. This was mainly done to fill the joint. This traditional process was slow and needed a lot of concentration from the welder hence the warm welcome of the new technology. There are different types of welding, namely spot welding, arc welding, metal inert gas welding, and forge welding (Welding, n. d.). Arc welding is the focus of this assignment. It is a process that uses electricity as a source of heat or energy needed to melt the metals before they are joined together. The welding process is so broad that mechanical engineering as a discipline is part and parcel of it. This discipline involves the design and manufacture of sophisticated products such as machines. Welding is used in the oil industry and it goes without saying that improving the technology will obviously lead to more profits within the industry. The United Arab Emirates is top on the list of the world’s greatest oil producers, and any developments in the process would greatly benefit these nations. The process of arc welding Within the process of arc welding are other types which are described below: Stick Welding or Shielded Metal Arc Welding (SMAW) In this process, the rod used is coated with a non-metallic material to protect the weld puddle and metal from contamination. The material burns to create a shield from oxygen. Sometimes, a filter is added onto the coating to act as a catalyst. This type of arc welding can be carried out outdoors because the flux protects the weld from oxygen and is not bothered by wind (Institute of Welding, 2006). Gas Metal Arc Welding (MIG) This is a type of arc welding where a bare wire is fed to the joint through a welding gun. Inert shielding gas flows to the welding handle protecting the weld from atmospheric contamination. The process itself is not hard, but rather the process of setting up the machine. Its disadvantage is that it cannot be effectively done outdoors as the wind can blow away the shielding. Tungsten Inert Gas Welding (TIG) As the name suggests, the rod used in this process is made of tungsten. It is not consumable functions by heating the metal while the filler is added when required. It is not part of the filler material. (Simonik, 1965). Choice of welding process The above processes are all applicable in different scenarios depending on what the manufacturer aims to achieve. If used effectively, production levels in any company are guaranteed to rise, and profits maximized. In the case of MIG, the process is considerably quicker as the metals are fired by machines at great speed. Unfortunately, there is a limit to the distance because the further you move from the wire the greater the friction (Welding S
