Performance level of system. This is done on artificial fault test piece as per ASTM A-275 which is supplied as a standard accessory with each equipment.
CIRCULAR MAGNETISATION - AC / HWDC
The job is clamped between two copper contact pads by operating pneumatic lever as well as mechanical. Magnetic fluid is flowed over the job using lever operated hand hose and while the fluid is still flowing a high current shot of desired strength is passed by pressing a foot switch. Duration of current flow which is controlled by electronic timer is generally 1/2 to 1 sec. The job is then inspected for longitudinal cracks using black light lamp. The cracks are seen as brilliant yellowish green lines.
LONGITUDINAL MAGNETISATION COIL / YOKE
In this mods of operation magnetic flux of the desired intensity is passed through the job by pressing a foot switch. The magnetic fluid is applied as before and the job inspected for transverse cracks. As the traverse of coil field is around 250 mm on either side the job is examined in suitable sections at a time.
In this mode of operation. circular and longitudinal fields are applied simultaneously. By use of this technique all cracks irrespective of their configuration are detected in a single examination. The rate of inspection is more than doubled by using this method. The limitation of coil field traverse as described above is applicable in this mode also.
