Abstract

METODO PARA DETERMINAR LOS ESFUERZOS RESIDUALES DE UN OBJETO MEDIANTE UNA FUSION PARCIAL DE SU SUPERFICIE. SE UTILIZA UN MEDIDOR DE DEFORMACION RESISTIVO DEL TIPO DE ROSETA CON TRES ELEMENTOS. CON UN HAZ CONCENTRADO DE LASER SE FUNDE UNA ZONA DE LA MUESTRA SITUADA EN EL CENTRO DE LA ROSETA (15). EL CAMBIO DE RESISTENCIA Y, POR TANTO, EL CAMBIO DE DEFORMACION DE LOS TRES ELEMENTOS DEL MEDIDOR DE DEFORMACION (11), (12), (13) SE MIDE ANTES DE QUE EL MATERIAL FUNDIDO SE HAYA SOLIDIFICADO Y ANTES DE QUE EL CALOR HAYA LLEGADO DEBAJO DE LOS MEDIDORES, SIENDO EL CITADO CAMBIO PROPORCIONAL A LOS ESFUERZOS RESIDUALES. SE APLICA AL ESTUDIO DEL INTERIOR DE TUBOS DE REACTOR SOMETIDOS A TENSOCORROSION.
