Just as conventional wet-hirizontal systems the electrical current used in multidirectional magnetization may be Alternating half-wave direct, or full-sized. It is also possible to use a combination of currents depending on the test applications.Multidirectional magnetization can be used for a large number of production application, and high volume inspections.
To determine adequate field strength and balance of the rapidly changing fields,techniques development requires a little more effort when multirectional equipment is used. It is desirable to develop the technique using a component with known defects oriented in at least two directions, or a manufactured defect standard. Quantitative Quality Indicators (QQI) are also often used to verify the strength and direction of magnetic fields.
