What this means to most folks is high inductance is good for thicker metals where good wetting at the toes of the weld is a priority and low inductance works better on thin metal.
Inductance of metal sheet.
L d 2 n 2 l 0 45d μh where d is the coil diameter in meters n the number of turns and l the coil length in meters.
A steady current produces a stationary magnetic field.
A steadily changing current alternating current or fluctuating direct current produces a varying.
If the current density is constant throughout each conductor 1 reduces to 3 which is independent of the current in either conductor and a function of only their dimensions.
