TIG (Tungsten Inert Gas) welding in a sheet metal fabrication workshop
Hi!
This is another detailed article of a series on the different welding methods that can be available in a sheet metal fabrication workshop. In this article, TIG.
Tungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTAW), is a welding process commonly used in sheet metal fabrication. It is a precise and clean process that can produce high-quality welds with minimal distortion.
TIG welding uses a non-consumable tungsten electrode to create an arc that melts the base metal and filler material. The weld pool is protected from atmospheric contamination by a shielding gas, typically argon or a mixture of argon and helium.
In sheet metal fabrication, TIG welding is commonly used to join thin sections of metal together. The process allows for precise control of the welding arc, which is particularly important when welding thin materials. TIG welding produces a narrow, focused heat source that minimizes heat input, reducing the risk of warping or distortion in the sheet metal.
One of the key advantages of TIG welding for sheet metal fabrication is its ability to produce high-quality welds with minimal spatter or discoloration.
TIG process is relatively slow compared to other welding methods. Additionally, the high precision required for TIG welding can make it difficult for beginners to master.
The metal surfaces to be welded should be clean and free of contaminants (rust, oil, grease, paint). Fit-up and joint design are also important considerations, as gaps or poor alignment can lead to weld defects. Tack welding may also be necessary to hold the pieces in place before making the final weld.
In conclusion, TIG welding is a versatile and precise welding process commonly used in sheet metal fabrication, due to high-quality welds with minimal distortion and spatter. However, its relatively slow speed and high precision requirements may be a limitation for some projects.
