In induction hardening the depth of hardening can be controlled by controlling
A)voltage
B)power factor
C)frequency
D)current
E)Parting off

Question

Quizplus · Accepted Answer

The depth of hardening in induction hardening can be controlled by adjusting the frequency. Higher frequencies result in shallower hardening depths, while lower frequencies allow for deeper hardening. This is because the electromagnetic field generated by the induction coil penetrates the workpiece to different depths depending on the frequency used.
