Lanthanated Tungsten Electrode
Description
1.5% lanthanated tungsten electrode, which is also known as WL electrode, contains a minimum of 97.80% tungsten and 1.30 to 1.70% lanthanum, or lanthana. To optimize your welding capabilities, you can consider it as a best choice.
Lanthanated electrode works well on AC or DC electrode negative with a pointed end or they can be balled for use with AC sine wave power sources. The lanthanum is dispersed evenly throughout the entire length of the lanthanated tungsten electrode in the process of production. This lanthanated tungsten electrode also maintains a sharpened point well, which is an advantage for welding steel and stainless steel on DC or the AC from squarewave power sources.
Compared to pure tungsten, the addition of 1.5% lanthana increases the maximum carrying capacity by approximately 50% for a given size electrode.
We can manufacture lanthanated tungsten electrodes with different content of lanthanum.
Features
Lanthanated tungsten electrode features excellent arc starting, low-burn-off rate, good arc stability and excellent re-ignition characteristics—many of the same advantages as ceriated electrodes. As 1.5% lanthanated tungsten electrode and 2% thoriated tungsten possess close resemblance, 2% thoriated, in some cases, can be replaced without having to make significant welding program changes.
Application
Unlike thoriated tungsten, these lanthanated tungsten electrodes are suitable for AC welding and, like ceriated electrodes, allow for the arc to be started and maintained at lower voltages.
