... adjustment for inflation ( Fig. 1.2 ). Electromagnetic induction, or simply “induction,” is a method of heating electrically conductive materials such as metals. It is commonly used in process heating prior to metalworking, and in heat treating, welding, and melting ( Table 1.1 ). This technique also...

.... The probe, moving through the diverted flux, generates a signal roughly proportional to the size of the flaw. On a longitudinal welded seam, an electromagnet with pole pieces on each side of the weld can be used to magnetize the weld area, with flux passing transversely across the seam. The magnetic flux...
