Abstract

PROCEDIMIENTO Y DISPOSITIVO PARA LA FABRICACION CONTINUA DE CUERPOS CON FORMA DE TUBO, EN LOS CUALES UNA CINTA DE ACERO REVESTIDA O SIN REVESTIR SE FORMA COMO UN TUBO CON RENDIJA Y LOS CANTOS DE CINTA QUE QUEDAN EN FRENTE SON SOLDADOS CON COSTURA LONGITUDINAL A GRAN VELOCIDAD MEDIANTE UN RAYO LASER DE GRAN DENSIDAD ENERGETICA, CON GAS PROTECTOR Y CON O SIN ALIMENTACION DE MATERIAL PROTECTOR. CON UNA PREPARACION DE AJUSTE DESPUES DE LA ZONA DE DERRETIMIENTO SE UNEN LOS CANTOS CON UNA SOLDADURA POR DERRETIMIENTO CON REFRIGERACION POSTERIOR Y RECALCADO, QUE PREPARA UNA GEOGRAFIA DE COSTURAS APROPIADA PARA CUALQUIER TRABAJO POSTERIOR.
