TUNGSTEN ELECTRODES
The TIG welder’s pride and joy: the
right tungsten electrode...because
without it, there’s no spark!
When choosing the tungsten electrode, the following aspects must
be taken into account:
Wherever finely crafted weld seams are created,
high-quality materials are welded and precisely welded joints are to be created, TIG welding is required
– and good tungsten electrodes. With tungsten inert
gas welding (TIG), in addition to the torch, the power
source and the shielding gas, the non-melting, temperature-resistant tungsten electrode is an essential factor
for optimal results.

As the name suggests, the main component of tungsten electrodes is tungsten. With the exception of the
green TIG welding electrode made of pure tungsten,
all the others are made with oxidic additives
such as zirconium oxide, lanthanum oxide,
cerium oxide or thorium oxide. Others
contain oxidic additives with rare earths.
You will find their effect and properties
under »TIG welding electrodes and their
color coding or doping« on this page.
TIG
The range of TIG welding electrodes is very extensive.
At the latest when it comes to choosing the right TIG
electrode for your own welding task, you will be confronted with colour coding of the tungsten electrodes.
The individual electrode types are marked with different colours. s can be easily removed with water and
further processing
of the workpiece can start immediately. In addition,
the weldability has been confirmed by an independent institute.
