Abstract

Un método de reparación de rieles e inserción para el mismo permite la reparación de rieles y estructuras tipo riel. Un defecto de riel inicialmente se identifica y se elimina como contenido en una porción de material volumétrico para formar un espacio vacío perfilado mientras mantiene continuidad del riel opuesto al espacio vacío. Una inserción preformada entonces se coloca en el espacio vacío por lo que efectúa una interconexión de riel a inserción. Una corriente se conduce a través de la interconexión a medida que la fuerza dirige la inserción contra el riel. El calor y la presión generados por una resistencia sueldan la inserción al riel. Los aspectos de soldadura por centelleo eliminan los óxidos y otras impurezas de la interconexión, y los aspectos de soldadura por forja crean una soldadura fuerte de estado sólido. El exceso de material, ya sea de rebabas, de riel o de inserción, se elimina durante los procesos de centelleo para proporcionar una reparación de riel virtualmente homogénea. La inserción de reparación de soldadura de estado sólido y la metodología subyacente habilitada por este medio puede utilizarse para reparar cualquier número de estructuras metálicas tipo riel especificas.
