Compared to conventional magnetic testing methods, the Gould-Bass Multi-Mag® systems offer substantial time and cost savings through efficient defect detection. The Multi-Mag® magnetizes parts in multiple directions in one firing sequence, so almost all defects can be revealed without having to process a part with a separate head shot and coil shot - conventional magnetization techniques are not nearly as efficient.
You can send current through power packs to test parts, with switching occurring at 0.0003-second intervals, through the multidirectional mode of the Multi-Mag®. You make 90 directional switches in a 0.5-second shot, with 30 occurring in each direction over a full 0.5-second. It is almost as though you are providing simultaneous magnetization while separating the application of field in all three directions. Based on the current control setting you set, current will flow for a duration of 0.000 to 0.009 second and will repeat itself every 0.009 seconds for the full duration of the magnetizing shot. This switching sequence occurs in all three of the power packs on an individual basis. You can carry out three different multidirectional magnetization modes with a choice of alternating current (AC), half-wave direct current (HWDC), or full-wave direct current (FWDC).
