Technical specifications

Tungsten electrodes of the brand WL-20 («blue» or «blue») contain lanthanum oxide, and are the standard consumables for inverter welding with direct and alternating current. Such electrodes are characterized by increased heat resistance and are specially designed for automatic welding processes due to a very good ignition characteristic. The welding current for AC welding should not exceed 250 A.

Lanthanide electrodes in the range of low-power welding processes have advantages over electrodes containing cerium oxide. Compared with pure tungsten, the addition of lanthanum increases the maximum conductive capacity by about 50 percent for a given electrode size.

Urgency of application

Tungsten electrodes WL-20 are used mainly for welding stainless and alloyed structural steels. Effective with plasma or microplasma welding. The presence of lanthanum increases the durability of these electrodes

In the conditions of sharp temperature fluctuations, which happens in automated welding with the use of welding robots (automobile and aircraft construction). Less effective for welding aluminum, as well as when used in welding processes with alternating current.

Chemical composition

In accordance with the technical requirements of ISO6848: 2004, the chemical composition and limitations in the use of WL-20 tungsten electrodes are:

Assortment and properties

Tungsten electrodes of the brand WC-20 are supplied in the range of diameters 0.5… 10 mm, with a length of 150… 200 mm, or otherwise, in case of individual order by the consumer.

These electrodes have a light arc ignition, low burning speed, good arc stability and excellent ignition characteristics. By specific conductivity are equivalent to toroidal electrodes.

Tungsten electrodes with a lanthanum and a pointed end work well for reverse polarity of alternating or direct current. When using them, a sharpened borehole must be constantly maintained, which is an advantage for welding steel and stainless steel on a constant or alternating current, and with a small voltage on the arc from energy sources that have a rectangular volt-ampere characteristic.

Supplier — the company AvekGlob — offers to purchase at affordable prices from manufacturers tungsten electrodes brand WL-20 (blue / blue). Products can be bought at a price formed on the basis of European and world standards of production. Implementation is possible in bulk and retail, for regular customers, a flexible system of discounts operates.
