Ceriated (Color Code: Orange)
Ceriated tungsten electrodes (AWS
classification EWCe-2) contain a minimum
of 97.30 percent tungsten and 1.80 to
2.20percent cerium and are referred to as
2 percent ceriated. Ceriated tungstens
perform best in DC welding at low current
settings.
They have excellent arc starts at low
amperages and become popular in such
applications as orbital tube welding, thin
sheet metal work. They are best used to
weld carbon steel, stainless steel, nickel
alloys, and titanium, and in some cases it
can replace 2 percent thoriated electrodes.
Ceriated tungsten is best suited for lower
amperages it should last longer than
Thoriated tungsten higher amperage
applications are best left to Thoriated or
Lanthanated tungsten.
Lanthanated (Color Code: Gold)
Lanthanated tungsten electrodes (AWS
classification EWLa-1.5) contain a minimum
of 97.80 percent tungsten and 1.30percent to
1.70 percent lanthanum, and are known as 1.5
percent lanthanated. These electrodes have
excellent arc starting, a low burn off rate,
good arc stability, and excellent re-ignition
characteristics. Lanthanated tungstens also
share the conductivity characteristics of 2
percent thoriated tungsten. Lanthanated
tungsten electrodes are ideal if you want to
your welding capabilities. They work well on
AC or DC electrode negative with a pointed
end, or they can be balled for use with AC
sine wave power sources. Lanthanated
tungsten maintains a sharpened point well,
which is an advantage for welding steel and
stainless steel on DC or AC from square wave
power sources.
