The process by which two materials like steel, aluminum, brass, and stainless steel are joined by fusing them is called welding and the welder is the equipment used for the process of welding. During the process the molten metal called filler is made used to keep the pieces that are to be attached as one. There are different types of energy sources that are and that can be made use of for welding matters. For example, powerful energy sources like gas flame, an electric arc, a laser, an electron beam, friction and ultra sound is used for the process of welding. There are different types of welding and they are mainly differentiated with the process by which they work. Arc welding, MIG welding, TIG welding, Stick welding are the types of welding that is in usage.

Mig Welding: Metal Inert Gas welding is known to be Mig Welding. This is also known to be Gas Metal Arc Welding or else GMAW. This is made use for fusing the metal aluminum with any other non-ferrous metal. It is used to join a many kinds of alloys and metals and we can only find a very little splatter in this kind of welding process. An unremitting, delicate wire electrode and shielding gas are supplied with a welding gun. The equipments necessary for this kind of welding is a welding gun, a wire feed unit, a shielding gas supply and an electrode wire. A steady and continuous source of power is required for welding a steel or aluminum. This kind of weld method is for the most part followed in the sheet metal manufacturing and is as a result a great deal used in the automobile manufacturing industries. . This technique is comparatively more rapid that other time honored techniques like the stick welding system.

Shield Metal Arc Welding is also being called and known as Manual Metal Arc in the trade. This method of welding is mainly used for welding steel stainless steel and cast iron materials. Things like a consumable electrode coated in flux are made use of to lay the weld in this Shield Metal Arc Welding. The equipments necessary for this kind of welding is a continuous power supply, an electrode, an electrode holder and a work clamp to hold.

TIG welding is nothing but Tungsten Inert Gas welding and this kind of welding is done manually. Magnesium and aluminum are the reactive metals that are joined with the process of TIG welding. An inert gas is used for this method as the source of energy. This type of welding is mostly used to join thin metals like aluminum, magnesium alloys, steel, stainless steel, copper, brass and titanium.

When compared with other welding processes Arc welding needs only low-cost tools and electric current as it’s energy source, which is easily acquired everywhere without trouble. One of the contemporary systems is a laser beam welding or energy beam welding.
