Tungsten electrodes are seen as a requisite for TIG welding. Choosing the best among the electrodes for aluminum welding can be done once you are aware of the properties and learn how well they can serve your welding purpose. But for that, a thorough study of each electrode is necessary.
TIG welding aluminum is quite common in the welding arena. And choosing the right tungsten is something that often raises questions. Well worry not, for today I am going to answer all your queries
Tungsten, unlike other metals, has a high melting point. In TIG welding especially, the electrodes used need to be non-consumable and tungsten is perfect for serving this purpose because of the said quality. Moreover, as aluminum is a tricky metal to weld, it demands good heat control and high temperature to melt which can be ensured only with tung.
