Abstract

PROCEDIMIENTO PARA REDUCIR LAS TENSIONES RESIDUALES DE SOLDADURA EN LA ZONA DE METAL APORTADO AFECTADA POR EL CALOR. COMPRENDE INTRODUCIR MECANICAMENTE EN LA ZONA DE METAL APORTADO AFECTADA POR EL CALOR Y EN METAL DE BASE ADYACENTE, TENSIONES DE COMPRESION SUPERIORES A SUS LIMITES APARENTES DE ELASTICIDAD INDIVIDUALES, PERO QUE NO EXCEDEN DE SUS CARGAS DE ROTURA A COMPRESION; DONDE LAS TENSIONES DE COMPRESION APLICADAS A LA ZONA DE METAL APORTADO AFECTADA POR EL CALOR Y AL METAL DE BASE ADYACENTE, CUANDO SE SUMAN A LAS TENSIONES DE SOLDAUDRA ORIGINALES, EXCEDEN DEL LIMITE APARENTE DE ELASTICIDAD DEL MATERIAL EN LA ZONA DE METAL APORTADO AFECTADA POR EL CALOR Y EN EL METAL DE BASE ADYACENTE, DANDO COMO RESULTADO UN FLUJO PLASTICO PERMANENTE DEL MATERIAL DONDE LAS TENSIONES EXCEDEN DE LOS LIMITES DE ELASTICIDAD.
