Wolfram WLa Elektroda

For tungsten inert gas welding (TIG), the non-fusing and temperature resistant tungsten electrode, in addition to the torch, the energy source and the inert gas, is a major factor for obtaining optimum results.

The following must be taken into consideration when selecting the tungsten electrode:

• Type of tungsten electrode
• Diameter of electrode
• Quality of the polished section and roughness of the electrode
• Tip geometry of the electrode

Lanthanated electrodes are suitable for applications in DC and AC welding. Their main areas of application are the welding of non-alloyed and high-alloyed steel, aluminium, titanium, nickel, copper and magnesium alloys. These electrodes are also suitable for the use in micro-plasma welding.

Ignition characteristics are enhanced with increased amounts of lanthanum oxide (La2O3). The overall service life and current carrying capacity is lower than the E3® electrodes.
