Merging and connecting two pieces of metal is not an easy task, and humans have tried for centuries to achieve this mission. However, the discovery of electricity and similar technological advancements were needed for a significant breakthrough in this field, and welding is nowadays a common activity in the metal industry. As a matter of fact, all sorts of industrial sectors are relying on welding to help them with assembling or connecting individual segments, and tungsten welding is one of the most popular methods of welding in the world.
That is why tungsten rod is a highly valuable tool in the modern-day metal manufacturing, and you should know a thing or two about this element before starting any actual welding.
What Is Tungsten Welding
TIG or tungsten inert gas welding is a procedure that has not changed for decades, and the basic principles of this process have remained the same. What this means is that an electric arc combines with a non-consumable tungsten electrode to connect the metal segments with the help of a filler metal. Because shielding gasses are also present during this activity, predominantly argon or helium, TIG welding is also commonly called GTAW – Gas Tungsten Arc Welding. Either way, this method can efficiently connect stainless steel or even some light materials, such as aluminum or magnesium. Lead and zinc are definitely out of the question, but TIG welding offers a broad range of options on which you can work.
The Features Of Tungsten Electrodes
Preparing your tungsten rod is the first step towards a successful welding process, and workers should always make sure that the tip of the rod is clean and ready. Aside from the actual preparation, the welders need to know which type of electrode should they use, and this choice will largely depend on the nature of the material that needs to be connected.
In other words, you can opt for tungsten electrodes which contain 97% of this rare material, and the rest comprises of similar rare metals, such as thorium, cerium, lanthanum, and so on.
