Description
Tungsten electrodes |
The tungsten electrode E3® (purple) developed by ABICOR BINZEL with oxides of rare earths as doping elements is suitable for both direct current (DC) and alternating current (AC) welding. Practically any metal can be welded with it. Because of its excellent ignition properties, it is therefore also often used for automated processes. During the welding process, the electrode temperature remains consistently low, which in turn ensures better current carrying capacity and a longer service life compared to thoriated electrodes. The latter may only be used in exceptional cases because of their extremely harmful effects. |

When choosing the tungsten electrode, the following aspects must be taken into account:
|
| Grinding quality and roughness of the electrode Before a tungsten electrode can be used, it must be ground, because in addition to the grinding quality, the grinding direction affects the arc. Important when grinding the TIG needle: The grinding direction must be longitudinal (axial) to the electrode! A bevel in the transverse direction (radial) to the TIG welding electrode causes a very restless, unstable arc. In addition, if incorrectly ground, the smallest tungsten particles can get into the weld pool and contaminate it. An axially ground tungsten electrode has good ignition properties, a stable arc and favorable electron emission. |

WP electrodes are not suitable for alternating current welding with the rectangular pulse waveform. In contrast, E3® electrodes achieve best welding results with high service life if the following parameters are complied with:
