Abstract

PROCEDIMIENTO PARA SOLDAR ENTRE SI TUBOS Y TRAVESAÑOS PARA FORMAR UNA PARED DE TUBO ESTANCA AL GAS, EN ESPECIAL PARA LA CONSTRUCCION DE CALDERAS DE VAPOR, UTILIZANDO EL PROCEDIMIENTO DE SOLDADURA BAJO POLVO, EN EL QUE SE ALIMENTA AL PUNTO DE SOLDADURA UN ADITIVO DE SOLDADURA EN FORMA DE HILO, POR MEDIO DE UNA CABEZA DE SOLDADURA, FORMANDO UN ARCO VOLTAICO. PARA AUMENTAR LA VELOCIDAD DE SOLDADURA Y MEJORAR LA CONFIGURACION DE LA COSTURA DE SOLDADURA, LA COSTURA DE SOLDADURA ES PRODUCIDA POR MEDIO DE DOS CABEZAS DE SOLDADURA SITUADAS CONSECUTIVAMENTE, LA PRIMERA DE LAS CUALES ESTA DIRIGIDA HACIA LA SUPERFICIE DEL TRAVESAÑO, PARA LA PRODUCCION DE UNA CAPA DE BASE O DE RAIZ, A UNA DISTANCIA EQUIVALENTE APROXIMADAMENTE AL DIAMETRO DEL HILO DEL ADITIVO DE SOLDADURA RESPECTO AL BORDE LONGITUDINAL DEL TRAVESAÑO, Y ESTA ORIENTADA CON UN ANGULO DE ENTRE 0 Y 20G RESPECTO AL PLANO DE REFERENCIA QUE TRANSCURRE EN ANGULO RECTO RESPECTO A LA SUPERFICIE DEL TRAVESAÑO Y EN PARALELO RESPECTO AL BORDE LONGITUDINAL DEL TRAVESAÑO, SOBRE LA HENDIDURA SITUADA ENTRE LA SUPERFICIE DEL TUBO Y LA SUPERFICIE LATERAL DEL TRAVESAÑO, APROXIMADAMENTE A LA ZONA DE LA MITAD DEL GROSOR DEL TRAVESAÑO, MIENTRAS QUE LA SEGUNDA CABEZA DE SOLDADURA ESTA INCLINADA RESPECTO A LA ORIENTACION DE LA PRIMERA CABEZA DE SOLDADURA CON UN ANGULO ENTRE 10G Y 40G EN SENTIDO CONTRARIO AL DE LA DIRECCION DE SOLDADURA, PARA REALIZAR LA SOLDADURA DE AVANCE DE PENETRACION DE UNA CAPA DE RECUBRIMIENTO.
