1. A method for controlling an induction welding operation, the method comprising:
sweeping electrical current through an induction welding coil at an initial position of the induction welding coil along a weld path of a material prior to any induction welding;
monitoring a response of the material to the swept electrical current using at least one electromagnetic field (EMF) sensor;
calibrating an electrical current value for the induction welding operation using the monitored response; and
performing the induction welding operation along the weld path using the calibrated electrical current value.
