| Abstract |
| | Railway axles are periodically tested for possible surface-breaking cracks. The magnetic particle inspection technique, a semi-automatic system, is used to detect any fatigue cracks on the axle. The wheelsets are conveyed to the machine along floor-laid tracks and lifted on to roller supports by dedicated hoist. The two novel features of the machine are the magnetizing procedure and the programmability of the coil position. High amperage current is supplied to the magnetizing coil from a separate power pack. The system also provides rapid demagnetization from a value of magnetizing current plus 10%. The equipment is supplied with a canopy for the inspection of axles for ultra violet fluorescent indications in subdued light. The canopy can be folded to allow wheelsets to be loaded from overhead. |
