The 2 main welding is TIG and MIG welding. TIG stands for Tungsten inert gas, what it isan arc welding process that uses a nonconsumable tungsten electrode to produce the weld. The weld area is protected from atmospheric contamination by a shielding gas (usually an inert gas such as argon), and a filler metal is normally used, though some welds, known as autogenous welds, do not require it. A constant -current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and metal vapors known as a plasma and MIG stands for Metal inert gas this is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW (Gas metal arc welding), but constant current systems, as well as alternating current, can be used.
There are four primary methods of metal transfer in GMAW, called globular, short-circuiting, spray, and pulsed-spray, each of which has distinct properties and corresponding advantages and limitations. All welding weather its MIG or TIG welding uses ARC which is the electric point when the welder hits the base of the metal that is been used to weld. These welding types are seen as a qualified trade in most country years of qualifeid training is needed to be able to have the craft of a qualified welder. ” Picasso did not become a legend in his craft over night, and just like welding it takes years of practise, practise and more practice.”(Brozda). Brozda also explained the new kind of welding that has come in over the last couple of years and explains the importance this kind of welding it has on the world right now, the welding is spot welding. Spot welding is a type of resistance welding used to weld various sheet metals. The welder is in shape of a bazooka gun and when you press the go butten 2 points of the gun hit on either side of the metal and The result is a small “spot” that is quickly heated to the melting point, forming a nugget of welded metal after the current is removed. All of theses weldings are essential for any car manufacturing companies.
Professional welders see there trade as a craft and as Brozda explains in his Article that it takes a long time to be the perfect welder. “Like professional athletes work hard to be the best at there sport and all the passion and hard work they put into getting better, to be a quality welder you need to do the same” (Brozda). Brozda is trying to get across to people who think welding is just an easy job and that there is no craft to it that they are wrong. Welding is a dangerous trade if you do not know what you are doing. You are working with Gas and a flame so you need to know exactly what you are doing before you can just jump in and do it. Before you can weld you have to inspect the welder for any kind of leeks and if there is bad hoses and these are all safety things you have to do, not much people would know that. Welders need to get one with there machine and study it and know the wright way to use it as each welder is different in the way it works. welding hose manufacturers
