Tungsten Inert Gas (TIG) welding is famous welding that uses tungsten electrodes to join different metals. The tungsten electrode is a basic part simultaneously, as it channels the current needed to build up the bend. The tungsten electrodes can be alloyed with an assortment of metals. Various sorts and sizes of electrodes are utilized for various welds and materials, and welders foster inclinations dependent on welding style and venture. Certain TIG electrodes perform better with rotating current (AC) rather than direct current (DC). Electrodes are delivered without a ground tip to make a tight, sharp point to accomplish an amazing and exact bend to guarantee a spotless weld.
There are many types of tungsten electrode types that are used for different applications. Each tungsten electrode has a distinct configuration of tungsten depending on its type. These tungsten electrodes are also recognized by their color codes:
Here we are describing the wide uses of blue tungsten electrode which is also known as 2% lanthanated tungsten electrode.
The blue lanthanide electrodes are mainstream because of the overall simplicity of striking a curve and the lower amperage required. They perform particularly well in both AC and DC applications and are mainstream general use electrodes. Blue electrodes are compelling for welding aluminum amalgams, magnesium combinations, nickel compounds, copper composites, titanium composites, low-alloyed prepares, and non-consuming prepares.
These electrodes have a superb curve beginning, a low burnoff rate, great curve security, and amazing reignition qualities—many similar benefits as ceriated terminals. Lanthanated electrodes additionally share the conductivity attributes of 2% thoriated tungsten. At times, 2% percent lanthanide tungsten can supplant 2% thoriated without making huge welding program changes.
Lanthanated tungsten electrodes are great, assuming you need to upgrade your welding abilities. They function admirably on AC or DC electrodes negative with a sharp end, or they can be balled for use with AC sine wave power sources.In contrast to thoriated tungsten, these blue tungsten electrodes are reasonable for AC welding and, as ceriated electrodes, permit the circular segment to be begun and kept up with at lower voltages. Contrasted and unadulterated tungsten, the expansion of 1.5 percent lanthana builds the greatest current-conveying limit by roughly 50% for a given terminal size.
