wolfraam elektrode
Wolfraam elektrode （Tungsten electrode） have a very high melting point of 3410 ° C. This makes tungsten electrodes eminently suitable for igniting and maintaining an electronic arc in the various metal processing processes, such as with TIG welding.
Material: Tungsten, and some different
Size: diameter 1.6mm, 2.4mm, 3.0mm, 3.2mm, 4.0mm and so on. we can make wolfraam elektrode （Tungsten electrode）in customized size.
Color: White, we also have wolfraam elektrode （Tungsten electrode）in other color such as green, blue, yellow, purple and so on.
Melting point: 3410 ° C
Application: TIG welding, ITIG welding
TIG-lTIG wolfraam elektrode （Tungsten electrode）is a specific welding technique. The name is an abbreviation and stands for Tungsten Inert Gas and owes its name to the English name for tungsten (tungsten) and the use of inert gas. TIG welding belongs to the "electric arc welding" category. The technique works with a non-melting electrode. This is made from tungsten, to which sometimes small amounts of other substances are added to improve the quality of the arc. Welding additive material is added separately, manually, to the melt bath.
With TIG welding, the heat is obtained by drawing a short-circuit arc between the tungsten electrode and the workpiece. This arc is usually started by a short-term high-voltage discharge; in the past, this device was lacking in cheaper equipment and the arc had to be ignited by stroking the workpiece, which had the disadvantage that both of them sometimes became fused and the welding electrode became contaminated.
The question we often get about tungsten electrodes, which color do I use with which material. Hence a brief overview. Available in different thicknesses.
You only use the color green for TIG aluminum welding.
The colors purple, turquoise and blue are excellent for use in welding ferrous steel, stainless steel, and aluminum.
The colors gold and gray are often advised for TIG welding of ferrous steel and stainless steel, whereby the gray can also be used for aluminum.
The color white is specific for aluminum welding where higher service life is desired than with the green color that has no addition (dope).
