TIG welding is one of the most complex yet most versatile welding methods. It produces high-quality, smooth joints with excellent strength. What does this method involve, which materials is it used for, and what are its advantages?
TIG welding is an excellent choice for applications that require high-quality welds. It is commonly used for welding materials such as aluminum, nickel, steel, and stainless steel. This process utilizes a tungsten electrode, which can withstand extremely high temperatures. With a melting point of up to 3,380°C, the electrode does not melt during the welding process. An electric arc generated by the electrode heats the material being welded. To protect the molten weld pool from reacting with air, a shielding gas is used, which helps ensure a high-quality weld. While the welding filler needs to be added manually, a mechanical wire feeder can be used to increase the speed of the process.
TIG welding is favored for its strength and visual appeal. This method does not produce deposits or fumes, and it eliminates spatter during the welding process. Additionally, TIG welding is versatile and suitable for a range of materials, including small surfaces and thin sheets. It offers excellent control over the weld pool, and the manual addition of filler material allows for precise application. As a result, this technique produces highly accurate welds.
TIG welding is primarily used for welding materials such as aluminum, stainless steel, nickel, and steel. It produces high-quality welded joints; however, it is not suitable for welding thick materials. Conversely, because TIG welding allows for the use of lower currents, it is an ideal choice for welding thin materials.
TIG welding requires both skill and experience. The welder must position the electrode close to the weld area without making contact. Once in position, the welder begins the welding process. The shielding gas creates a protective atmosphere, while the electric arc melts the materials being welded. The filler material is added with the opposite hand. After both materials merge, the welder stops the electric arc. The shielding gas continues to flow through the torch for a short period to protect the weld area as it solidifies.
