There are various tungsten electrodes that you can use for the process but not all will.
Tungsten welding rod colors.
Increased ignitability thanks to lanthanum oxide.
Different types and sizes of electrodes are used for different types of welds and materials and welders develop preferences based on welding style and project.
The tungsten electrodes can be alloyed with a variety of metals.
Suitable for dc and ac welding.
And for microplasma welding.

Can be used for unalloyed and high alloy steels.
Tungsten electrodes for ac welding of aluminium alloys.
The process utilizes a non consumable tungsten electrode that relays current to the welding arc.
In addition tip preparation is critical.
The electrode choices are pure tungsten 2 percent thoriated 2 percent ceriated 1 5 percent lanthanated zirconiated and rare earth.
The end preparations are balled pointed and truncated.
The best way to learn how is just by welding.
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw.
Tig stands for tungsten inert welding and in a more technical sense it s known as gas tungsten arc welding gtaw.
Only limited suitability for dc welding.
