There are various tungsten electrodes that you can use for the process but not all will.
Tungsten welding rod colors.
The electrode choices are pure tungsten 2 percent thoriated 2 percent ceriated 1 5 percent lanthanated zirconiated and rare earth.
Arc length bead length temperature of base material how clean and smooth the surface is tungsten angle your motion while welding the direction you re welding if there s a back purge or backing plate and post flow all affect the final color or lack thereof.
Choosing one of the six commonly available tungsten electrodes is a crucial first step in successful gas tungsten arc welding gtaw.
The best way to learn how is just by welding.
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.
Suitable for dc and ac welding.
The end preparations are balled pointed and truncated.
And for microplasma welding.
Increased ignitability thanks to lanthanum oxide.
Only limited suitability for dc welding.
Aluminium titanium nickel copper and magnesium alloys.
Tungsten electrodes for ac welding of aluminium alloys.
The tungsten electrode is a critical component in the process as it channels the current required to establish the arc.
The process utilizes a non consumable tungsten electrode that relays current to the welding arc.
The tungsten electrodes can be alloyed with a variety of metals.
Can be used for unalloyed and high alloy steels.
