People have always wanted to find ways to easily and efficiently connect separate pieces of metal, but until electricity was discovered – this task was not possible to accomplish. Electric energy changed the game completely, and welding is nowadays a backbone of the modern metal industry. In other words, we can quickly connect separate segments in a convenient manner.
And our technique and technology are so advanced that the actual places of connection are almost invisible. TIG welding is one of the methods which allows for this type of quality and seamless connectivity, but operating a TIG welding rod is not as easy as it may seem at first.
Different Types Of Tungsten Electrodes
Electrodes are an integral component of the welding process, and they significantly affect the quality of the end-product. When it comes to TIG welding, tungsten electrodes are in use with this particular method, and they can come in several different versions. Tungsten itself is a highly durable material, and it can even sustain temperatures of 3.410º C without melting.
In combination with power supply, an electric arc is formed, and this field enables the filler metal to connect two pieces of metal. Some electrodes contain 99,5% of tungsten, and they are called pure tungsten electrodes, and their code color is green. Other types include slightly lower amounts of this rare material, typically 97.3% and the rest is “occupied” by lanthanum, thorium, or some other similar metal.
How To Handle A Tungsten Welding Rod
One of the essential advantages of TIG welding comes from the fact that this method does not produce smoke of fumes as side effects.
Which means that operators can clearly see the surface that they are working on. Due to this visibility, and the fact that a TIG welding rod can be held like a pen, workers with sufficient experience can easily create intricate work and produce welds of impressive quality and aesthetic value. Clean and precise, these welds are durable as well, and different sub-categories of tungsten welding are present in the current market, including dabber, hot wire, or pulsed-current TIG welding.
