Latest Price of Lanthanated Tungsten Electrode (WL20) on July 7, 2022

The latest price of Ø2.4x175mm lanthanated tungsten electrode (WL20) is 1.10 USD/PC on July 7, 2022, EXW XIAMEN, CHINA. 

WL20 electrodes contain at least 1.7% to 2.2% lanthanum for excellent arc starting, low burnout rate, good arc stability and excellent re-ignition characteristics. They are ideal if you want to optimize your welding capabilities. They can work well on either AC or DC electrode negatives with tips, or they can be used with AC sine wave power supplies. The tungsten electrode adding with rare earth element lanthanum holds sharp tips well, which is an advantage for welding steel and stainless steel on DC or AC from square wave power sources.

Lanthanated Tungsten Electrode WL20

Introduction

Electrodes by adding 1.8% -2.2% of lanthanum oxide into tungsten can be called as WL20 lanthanated tungsten electrode. It has the highest content of lanthanum oxide in all lanthanum tungsten electrodes, so its performance will be relatively improved. High content of lanthanum oxide can make the type of electrode quickly ignite the arc, such as welding rod, wire and so on.

Trademark

Because of high content of lanthanum oxide, WL20 lanthanated tungsten electrode is often used in place of thorium tungsten electrode, which has lanthanum oxide content of 1.80 to 2.20%. Content of other impurities is less than 2.0%. Although the content of lanthanum oxide are the highest among three lanthanum tungsten electrodes, but its tungsten content is relatively low. Electrode tip color is sky blue.

Code	Impurity		Other Impurities%	W%	Color
	Type	Content%
WL15	La2O3	1.80~2.20	<0.20	＞97.5	Sky Blue

Characteristic

Lanthanum tungsten electrode has 2% lanthanum oxide which may be one of the best tungsten electrodes to replace thorium tungsten electrode. Compared to thorium tungsten electrode, lanthanum tungsten electrode has a good arc characteristic, igniting in faster speed with a longer life. It is mainly used in AC and DC power inverter and transformer welding. Conductivity of lanthanum tungsten electrode is most closed, which is a two percent of thoriated tungsten electrode, having excellent welding effect.

Packing

Each tungsten electrode packed in plastic case, 10 to a plastic case, and its length is 150mm or 175mm, 1000 pieces per box.

Lanthanated Tungsten Electrode WL15

Introduction

Containing 1.3% to 1.7% lanthanum oxide of tungsten electrode can be the known as WL15 lanthanated tungsten electrode. W is the abbreviation of Wolfram, L represents lanthanum oxide. Its electrode tip color is golden yellow. Lanthanum oxide in the electrodes can extend its life, but at the time of delivery of lanthanum oxide, the operator must pass rigorous specialized training. It’s better to wear gas masks, safety glasses, anti-static overalls, rubber gloves and make other protective measures.

Trademark

Lanthanum tungsten electrode is used to replace thorium tungsten electrode in most applications. WL15 lanthanum tungsten electrode has lanthanum oxide content of 1.3% to 1.7%. Content of other impurities is less than 2.0%.

Code	Impurity		Other Impurities%	W%	Color
	Type	Content%
WL15	La2O3	1.3-1.7	<0.20	＞97.5	Golden Yellow

Characteristic

Electron work function of lanthanum tungsten electrode WL15 is 2.7-2.8eV, which is similar to thorium tungsten electrode, and the most important is that it has not radioactive damage. Compared to thorium tungsten electrode, this electrode arc performance and burning resistant will be better. Another advantage is that its durable current is high but the burn rate is very small, so the lanthanum tungsten electrode enjoys a great popular in Asia, Europe, America and Japan and other countries. Tests showed that conductivity of lanthanum tungsten WL15 is the closest to WL20 thorium tungsten electrode, welder can easily replace electrode without adjusting the parameters of the device.

Packing

Each tungsten electrode packed in plastic case, 10 to a plastic case, and its length is 150mm or 175mm, 1000 pieces per box.

Lanthanated Tungsten Electrode WL10

Introduction

Adding 0.80 ~ 1.20% lanthanum oxide into tungsten can be called as WL10 lanthanated tungstenelectrode. Content of lanthanum oxide of lanthanated tungsten electrode is less but the tungsten content is the greatest, which can brilliantly resist thermal shock, even in excess of the current load it can be maintained working at a longer period. Its electrode tip color is black.

Trademark

Although WL10 lanthanum tungsten electrode only contains 1% lanthanum oxide, but it can improve the effect of welding to a certain extent. It has 98.4% tungsten, which cannot easily be oxidized and wore. Its color is black electrode.

Lanthanated Tungsten Electrode-Chinatungsten

The lanthanated tungsten electrode is becoming more popular in the circle of welding in the world soon after they were developed, because of their good welding performance. The electric conductivity of lanthanated tungsten electrode is most closed to that of 2% thoriated Tungsten electrodes. Welders can easily replace thoriated tungsten electrodes with lanthanated tungsten electrodes at either AC or DC and not have to make any welding program changes.

The radioactivity from thoriated tungsten electrodes can thus be avoided. Another advantage of lanthanated tungsten electrode is being able to be bear high current and having the lowest burn-loss rate.
