Arc Performance of Welding Cerium Tungsten Electrode

Cerium tungsten electrode arc performance is better (with respect to thorium tungsten electrode), this is because: With the decline in work function of cerium tungsten electrode, the cathode fall will be reduced, so that the cathode spot become smaller, and ultimately launch also be able to concentrate. As the arc current increases, the arc generated by the magnetic field with increasing pressure of the heart, and therefore, the arc will be compressed (by a large current), finally the emission current density of the cerium tungsten electrode will be improved.

When welding the work piece, at the central axis of the arc, the density of metal vapor generated when the arc heating weld pieces is the highest, and its resistance is relatively large. In addition, when the cathode voltage drop down, the cathode arc spots loss will be reduced, so that the construction arc can also be carried out at low current, and the arc is easier to stretch, which creates the conditions for the metal foil welding.
