Abstract
La presente invención se refiere a procedimiento para soldar bifurcaciones de tubos a la pared de un recipiente provista de perforaciones, en que la bifurcación del tubo, en el extremo que se va a soldar está ahusada cónicamente hacia adentro a partir del diámetro exterior y, partiendo del diámetro interior cilíndrico, se halla provista de una superficie de elevación de forma anular, con la cual la bifurcación del tubo se monta sobre una contra-superficie correspondiente que, rodeando la pared del recipiente, está construída a modo de cierre superior de un cuello ya elaborado, de tal manera que se somete a la soldadura libre de fisuras residuales una costura de soldadura, de forma de anillo, ya preparada; el procedimiento está caracterizado en que la superficie de elevación de forma de anillo de la bifuración del tubo está construída en ángulo recto con respecto del eje central de la bifuración del tubo, en el extremo de una bifuración cilíndrica, cuyo diámetro interior corresponde al diámetro interior de la bifurcación del tubo y cuyo diámetro exterior, independientemente del diámetro de la perforación, es aproximadamente 2 mm más grande que el diámetro interior; en que también el cuello de la pared del recipiente se halla provisto de una prolongación que constituye la contrasuperficie, de dimensiones que corresponden a la prolongación que va en la bifurcación del tubo; en que la longitud axial de las dos prolongaciones equivale en total aproximadamente de 2 a 3 mm, y en que, para soldar la bifurcación del tubo con la pared del recipiente mediante la soldadura de metal y gas activo ya conocida, se introduce en la perfora ción un anillo de soporte hecho de cerámica que sobresale de la zona de las dos prolongaciones, centra la bifurcación del tubo en relación con la pared del recipiente, impide que se forme una saliente de raíces de soldadura y, una vez concluída la operación de soldadura, por lo menos de una sola aplicación, se destruye y se elimina.The present invention relates to a method for welding pipe branches to the wall of a container provided with perforations, in which the pipe branch, at the end to be welded, is tapered inwardly from the outer diameter and, starting of the cylindrical inner diameter, it is provided with a ring-shaped lifting surface, with which the bifurcation of the tube is mounted on a corresponding counter-surface that, surrounding the wall of the container, is constructed as a top closure of a neck ready made in such a way that a ready-made ring-shaped weld seam is subjected to residual crack-free welding; The procedure is characterized in that the ring-shaped lifting surface of the tube branch is constructed at a right angle with respect to the central axis of the tube branch, at the end of a cylindrical branch, the inside diameter of which corresponds to the inside diameter. of the tube bifurcation and whose outer diameter, regardless of the diameter of the perforation, is approximately 2 mm larger than the inner diameter; in which the neck of the container wall is also provided with an extension that constitutes the counter surface, with dimensions corresponding to the extension that goes at the bifurcation of the tube; in which the axial length of the two extensions equals in total approximately 2 to 3 mm, and in which, in order to weld the bifurcation of the tube with the wall of the container by means of the weld of metal and active gas already known, it is introduced into the hole tion a support ring made of ceramic that protrudes from the area of the two extensions, centers the bifurcation of the tube in relation to the wall of the container, prevents a protrusion of welding roots from forming and, once the welding operation is completed , from at least a single application, is destroyed and removed.
