Mobile power packs like the P-70 and P-1500 are ideal equipment for on-site magnetic particle inspection. They are convenient and economical for MPI applications that only require a moderate amount of magnetizing power. Using 4/0 cables and various accessories to complete the circuit, a power pack can be a very versatile NDT tool.
Our power packs are equipped to supply both half wave direct current and alternating current. By wrapping a 4/0 cable around a part or using prods with the supplemental NDT materials, inspectors can find surface or sub-surface indications on parts.
As current moves around or through a part an electromagnetic field is induced. Any slight discontinuity in the part, such as a hairline fracture, will cause that perfectly symmetrical field to be disturbed. This disturbance in the field will cause our NDT material to cluster, due to the iron particles in the mixture. The inspector need only look for the clustered materials, whether they be visible dye, dry powder, or fluorescent.
Magnaflux understands the physics behind magnetic particle inspection and has been working to make the process easier on the operator, as well as more efficient for the equipment. Here are the top ways to do that:
