Abstract

La invención se refiere a un método para determinar la resistencia eléctrica lineal en modo alterno de una tubería de acero, que comprende los pasos de generar en una porción (4) de la tubería una corriente inducida por medio de una bobina de inducción (6) centrada en un eje longitudinal (X-X) de la tubería y atravesada por una corriente alterna, estando la bobina alojada en una cabeza de cilindro (8) de material ferromagnético para confinar el campo magnético sobre una superficie predefinida de la porción de tubería, medir la potencia activa disipada por la porción de tubería sometida al campo magnético, medir la amplitud del campo magnético producido, y determinar la resistencia eléctrica lineal en modo alterno de la porción de tubería a partir de las mediciones de la potencia activa disipada y de la amplitud del campo magnético inducido. La invención también se refiere a un dispositivo (2) para implementar dicho método.
