Abstract

PROCEDIMIENTO PARA SOLDAR TUBOS DE PARED DELGADA DE UN INTERCAMBIADOR DE CALOR AL LADO POSTERIOR DE UNA PLACA PARA TUBOS. LA PRESENTE INVENCION SE REFIERE A UN PROCEDIMIENTO PARA LA SOLDADURA DE TUBOS DE PARED DELGADA PARA INTERCAMBIADORES DE CALOR CON EL LADO POSTERIOR DE UNA PLACA PARA TUBOS (1), SIN DEJAR NINGUNA HENDIDURA RESIDUAL, ESTANDO DICHA PLACA PARA TUBOS PROVISTA DE ORIFICIOS (2) CORRESPONDIENTES AL DIAMETRO INTERIOR DE LOS TUBOS (5), Y DE CUELLOS (3), CONFIGURADOS A PARTIR DEL MATERIAL DE LA PROPIA PLACA PARA TUBOS (1), QUE RODEAN CONCENTRICAMENTE A DICHOS ORIFICIOS (2), CON CUYA SUPERFICIE FRONTAL (4) SE SUELDA LA SUPERFICIE FRONTAL (6) DE LOS TUBOS CENTRADOS (5) SIN NECESIDAD DE MATERIAL ADICIONAL, POR MEDIO DE UN CABEZAL SOLDADOR QUE GIRA EN EL INTERIOR DEL ORIFICIO (2), DE ACUERDO CON EL PROCEDIMIENTO DE SOLDADURA CON ELECTRODO DE WOLFRAMIO EN ATMOSFERA DE GAS INERTE (WIG). PARA EL CENTRADO DE LOS TUBOS (5) RESPECTO A LA PLACA DE TUBOS (1) Y PARA LA FORMACION DE UN SOPORTEPARA EL BAÑO DE SOLDADURA EN EL LADO EXTERIOR DE LA UNION A SOLDAR, SE UTILIZA UN ANILLO DE CERAMICA (7), QUE SIRVE TANTO PARA EL CENTRADO DEL RESPECTIVO TUBO (5) RESPECTO AL CUELLO (3) EN LA PLACA PARA TUBOS (1), COMO TAMBIEN COMO SOPORTE PARA EL BAÑO DURANTE LA OPERACION DE SOLDADURA, DE MODO QUE DICHO ANILLO RODEA LA ZONA DE UNION A SOLDAR POR SU LADO EXTERIOR.
