The modern metal industry uses several primary methods of welding, and tungsten or TIG welding is one of the most prominent ways of how two pieces of metal can be joined. Another name for this method is GTAW, which comes from Gas Tungsten Arc Welding, and argon or helium are usually used as shielding gasses in the welding process.
Of course, workers who are performing this type of welding need to have the proper equipment, and besides protective gear, they also have to use a power supply unit and a TIG welding rod. Electrodes for tungsten welding come in various types, and here are the most prominent ones.
Types Of Tungsten Electrodes
Tungsten is a highly durable metal, and it has the highest melting point of all metals on the planet, which makes it perfect for conducting high amperage. Since electrodes can contain varying amounts of actual tungsten, manufacturers are adding other metals to boost the performances of the rods and to make the welding process more efficient. For instance, pure tungsten electrodes are marked with green color, and they contain 99,5% of this rare metallic element. Other types of electrodes comprise of around 97% of tungsten, and the rest is thorium, cerium, lanthanum, or zirconium. Also, there are electrodes which include rare earth oxides, i.e. a hybrid combination of these elements, and some of these electrodes can offer superior stability and less tungsten spitting than others.
Advantages Of Using TIG Rods
Tungsten rods and TIG welding, in general, can offer a broad range of benefits over other welding methods, which means that many industrial areas are relying on this particular type of welding.
It is possible to perform intricate work with TIG welding rod, and precision and ultimate control are the dominant characteristics of tungsten welding. Other than that, TIG welding is highly flexible, which means that it can be used to connect various materials, but it is mostly used for welding aluminum, titanium, copper, bronze, and so on. Another benefit of its flexibility comes from the fact TIG welding can be performed in tight spaces and confined areas.
