Tungsten electrode
An electrode is a rod based on an electrically conductive material for
supplying current to a welded product (pipe, sheet, corner, square.
Currently, there are more than 100 brands of electrodes in Ukraine, and
more than half of the electrodes produced are melting for manual arc
welding. two types of welding are argon and arc.
A tungsten electrode is one of the most effective electrodes since
tungsten is the most refractory metal present on earth, its melting
point is 3410 ° С, boiling point is 10220 ° С, density is 19.3 g / cm^3.
Hardness is maintained even when the temperature reaches 400-500 ° C.
The consumption of tungsten during welding is very small - hundredths of
a gram per 1 meter of the weld, and tungsten electrodes alloyed with
oxides and rare-earth elements are even more resistant!
At this time, tungsten electrodes have a diverse chemical composition
with different properties. To achieve higher characteristics during
welding, various oxides of various rare-earth metals are introduced into
tungsten, such as: lanthanum, yttrium, cerium, zirconium and thorium.
Refractory tungsten electrodes are used exclusively for welding metal in
an inert atmosphere. This is the only way to weld austenitic steel by
portable welding outside the conditions of a special chamber. The low
fusion coefficient of these electrodes allows you to weld very thin
parts, up to the thickness of the foil. Another area of application is
the welding of refractory alloys, when the thermal stability of the
electrode should be extremely high.
Due to its refractoriness, tungsten electrodes provide an extremely low
material consumption per 1 meter of seam. To carry out such an
operation, it is necessary to spend milligrams of metal. Those who
believe that buying tungsten electrodes means harming themselves are
mistaken. Despite the high cost, they pay off with this expense. In
addition, they can significantly reduce working time to perform tasks of
large volume. They demonstrate high thermal stability, due to which it
is possible to precisely comply with the welding process with a minimum
percentage of rejects.
Products are manufactured at partner enterprises, therefore tungsten
electrodes are available to our customers at a low price. MetalKomplekt
guarantees strict compliance with GOST and ISO standards. In production,
total quality control is used at each stage, so the marriage is
excluded.
The difference between a conventional electrode and a tungsten
Compared with argon arc welding, the quality of the seam with the
tungsten electrode is much higher, it turns out to be almost continuous.
Despite the high cost of the tungsten electrode, it is much more
profitable due to the low consumption of material.
What determines the cost
The price of a tungsten electrode directly depends on the amount of
metal that went into its manufacture..
