Abstract

Es un objeto de la presente acta proveer un método de ensayo de corriente parásita capaz de detectar en forma segura una parte de alta dureza localizada que se produce en un material metálico que tiene magnetismo, y capaz de verificar en forma segura si la parte de alta dureza ha sido removida luego de la ejecucion de un tratamiento de reparacion para remover la parte de alta dureza. En el método de ensayo de corriente parásita de acuerdo con la presente acta, una frecuencia de la corriente alterna CA para energizar la bobina diferencial 1 es establecida de manera tal que una diferencia de fase entre una senal de variacion del magnetismo del material metálico P y una senal elevada detectada por la bobina diferencial es igual a o mayor de 135°, y una parte de alta dureza localizada que se produce en el material metálico es detectada en base a una amplitud y una fase de una senal de deteccion que sale de la bobina diferencial.It is an object of the present act to provide a parasitic current test method capable of safely detecting a part of high localized hardness that is produced in a metallic material that has magnetism, and capable of verifying in a secure way whether the high part hardness has been removed after the execution of a repair treatment to remove the high hardness part. In the parasitic current test method according to the present act, a frequency of the alternating current AC to energize the differential coil 1 is established such that a phase difference between a signal of variation of the magnetism of the metallic material P and a high signal detected by the differential coil is equal to or greater than 135 °, and a part of high localized hardness that is produced in the metallic material is detected based on an amplitude and a phase of a detection signal leaving the coil differential.
