The blue lanthanated electrodes are popular due to the relative ease of striking an arc and lower amperage required. They perform exceptionally well in both AC & DC applications, and are a popular general use electrode. Blue electrodes are effective for welding aluminum alloys, magnesium alloys, nickel alloys, copper alloys, titanium alloys, low-alloyed steels, and non-corroding steels.
Grey ceriated electrodes are popular due to their extreme ease of striking an arc with lower amperages, and their extraordinary performance with regard to DC welding applications. They perform best with titanium alloys, copper alloys, magnesium alloys, aluminum alloys, nickel alloys, non-corroding steels, and low-alloyed steels.
WC20 Welding cerium Tungsten Electrode
Cerium-tungsten electrode is a non-radiative and green products .It has good starting arc performance under the condition of low current .It is known to be especially good for direct current welding with low amperage because it starts very easily at low amps .Therefore it is very popular to be used for the welding of pipeline ,fine parts, short welding cycles and given number welding .
The gold lanthanated tungsten electrodes contain less lanthanum than their blue counterparts and are best used in DC applications. They are best for welds with titanium alloys, copper alloys, nickel alloys, and non-corroding steel.
The red thoriated type is Americas favorite electrode for a reason. Extremely long lasting and highly durable, these electrodes are a staple in DC welding applications. These red electrodes are best for copper alloys, nickel alloys, titanium alloys, and non-corroding steels.
WT Thorium- Tungsten Electrode
It is widely used as an additive oxide electrode ,having much more advanced comprehensive welding performance than the properties of Pure Tungsten Electrode and other additive oxide electrodes. It can not be replaced by other oxide electrodes during the long use process. It can be operated easily and current load is high .It can produce arc easily and steadily ,and the gap of the? breaking arc is big ,loss less and long life .It has much higher recrystallizing temperature, much better conductivity and better mechanical cutting property .It is used for welding carbon steel, stainless steel, nickel alloy and titanium metal. It is the first selection material for high quality welding.
