    Only tungsten powder with a very high purity of at least 99.95% without additional alloying elements is used in the production of WP electrodes. After brief mixing, the powder is filled into a mould and compacted, then sintered into a rod and brought into the final shape by rotary swaging, drawing, grinding and other methods. The electron work function is high at 4.5 eV, which is why the temperature increases at the tip and the microstructure recrystallises. The service life is comparatively short. WP is generally used only for AC welding, for example on aluminium and magnesium alloys.
