Abstract

QUE COMPRENDE DOS BORDES DE UN METAL BASICO PARA PRODUCIR UNA ESTRUCTURA SOLDADA CON UNA RESISTENCIA A LA TRACCION DE 900 MPa, DICHA SOLDADURA TIG (SOLDADURA POR LLAMA DE GAS DE TUNGSTENO INERTE) DE BAJO CONSUMO CALORIFICO, SE HACE A UNA ENERGIA DE ARCO DE 0,3 KJ/mm A 1,5 KJ/mm Y A UN PRECALENTAMIENTO DE 100�C USANDO UN GAS PROTECTOR BASADO EN ARGON CON 1% POR PESO DE OXIGENO Y UN ALAMBRE CONSUMIBLE PARA SOLDAR. DICHA ESTRUCTURA SOLDADA COMPRENDE: I) UN METAL DEPOSITADO QUE TIENE UNA DBTT (TEMPERATURA DE TRANSICION DUCTIL A FRAGIL) DEBAJO DE 73�C CON UNA MICROESTRUCTURA QUE COMPRENDE: A) UNA ESTRUCTURA DE CRISTAL BBC DE GRANO FINO DOMINADA POR MARTENSITA EN LISTON AUTOTEMPLADA; Y B) UN BAJO CONTENIDO DE INCLUSION NO METALICO; DICHO METAL DEPOSITADO COMPRENDE HIERRO Y LOS SIGUIENTES ELEMENTOS DE ALEACION: 0,06% A 0,1% DE CARBONO, 1,6% A 2,05% DE MANGANESO, 0,20% A 0,32% DE SILICONA, 1,87% A 4% DE NIQUEL, 0,40% A 0,56% DE MOLIBDENO, 0,30% A 0,87% DE CROMO, 30 ppm DE AZUFRE Y 50 ppm DE FOSFORO, ADEMAS COMPRENDE UN ADITIVO SELECCIONADO DEL GRUPO CONSISTENTE DE: 0% A 0,30% DE COBRE, 0% A 0,02% DE ALUMINIO, 0% A 0,015% DE ZIRCONIO Y 0% A 0,01% DE TITANIO; II) UNA ZONA AFECTADA POR EL CALOR(HAZ); Y III) PORCIONES DE DICHO METAL BASICO EN LA CERCANIA DEL HAZ (PORCION DEL METAL QUE NO SE FUSIONA DURANTE LA SOLDADURA)
