The amount of metal evaporating from the cathode spot (Part 2).
Since the total length of the cathode zone (the ionization zone and the free-motion zone of the ions adjacent to the cathode surface) is several mean free paths...

At present, it is considered that the value of the ion fraction of the current in the welding arcs is approximately β ≈ 0.5. Assuming that the value of β does n...
