Abstract

SE DESCRIBE UN METODO PARA SOLDAR ACERO INOXIDABLE COMO UNA CLAVIJA FINAL DE ACERO INOXIDABLE EN UNA VARILLA DE COMBUSTIBLE NUCLEAR DE ACERO INOXIDABLE. EL PROCESO DE SOLDADURA TIENE UN ERROR DE ARCO REDUCIDO Y UNA PENETRACION DE ARCO MAS PROFUNDA. TAMBIEN SE DESCRIBE UN ELECTRODO DE SOLDADURA TRATADO PARA PRACTICAR EL METODO. UNA CAPA DE ACERO INOXIDABLE SE COLOCA EN EL EXTREMO DE DESCARGA DEL ARCO DE TRABAJO DE UN ELECTRODO DE SOLDADURA POR ARCO DE TUNGSTENO NO-CONSUMIBLE ANTES DE SOLDAR. EL REVESTIMIENTO DE ACERO INOXIDABLE DEL ELECTRODO REDUCE EL ERROR DEL ARCO Y PERMITE UNA PENETRACION DEL ARCO MAS PROFUNDA. SE COLOCAN APROXIMADAMENTE ENTRE .001 Y .005 PULGADAS DE ACERO INOXIDABLE EN EL EXTREMO DE DESCARGA DEL ARCO DE TRABAJO DEL ELECTRODO. EL REVESTIMIENTO DEL ELECTRODO PUEDE FORMARSE COLOCANDO EL EXTREMO DE DESCARGA DEL ARCO DE TRABAJO DEL ELECTRODO CERCANO A UNA PIEZA PUESTA A TIERRA DE ACERO INOXIDABLE Y LUEGO ACORTANDO ELECTRICAMENTE EL ELECTRODO AL ACERO INOXIDABLE DE TAL FORMA QUE EL EXTREMO DE DESCARGA DEL ARCO DE TRABAJO SE PEGUE AL ACERO INOXIDABLE. EL EXTREMO DE DESCARGA DEL ARCO DE TRABAJO DEL ELECTRODO SE ROMPE DESDE EL ACERO INOXIDABLE DE TAL FORMA QUE UNA CAPA DE ACERO INOXIDABLE PERMANECE EN EL.
