Abstract: The process comprises introducing the tubes in the form of horizontal layers (the generator can be positioned horizontally for this purpose), installing anti-vibratory bars on the layers, placing weights on the bars and checking the clearances between the tubes and the bars, so that the tubes falling outside the accepted tolerances can be replaced. This is followed by the installation of the layer of tubes immediately above it. This procedure is repeated until all the layers have been installed. The invention is used in the steam generators of nuclear power stations.

Abstract: The present disclosure describes a process for the installation of tubes in a steam generator. It essentially comprises introducing the tubes in the form of horizontal layer, whereby the generator can be positioned horizontally for this purpose; installing antivibratory bars on the layers; placing weights on the bars and checking the clearances between the tubes and the bars, whereby the tubes falling outside the accepted tolerances can be replaced. This is followed by the installation of the layer of tubes immediately above it. This procedure is repeated until all the layers have been installed. The present invention can be applied to the steam generators of nuclear power stations.

Abstract: Method of making a great number of weld beads in the form of independent contours spaced apart by means of an automatic welding head comprising a torch and means for displacing the torch in several directions allowing the latter to follow each contour one after the other. The method is characterized by the fact that after striking of the arc and positioning of the torch on the first contour to be welded and then making of the first weld bead have been effected in a known way, the torch current is decreased to effect a partial fading out of the arc. A displacement of the torch is then effected as far as a starting position on a second contour to be welded, and a timed stationary preheat is effected at this point by controlling the return to welding current. The second weld bead is made by following the second contour to be welded, the torch current is then decreased to obtain a further partial fading out of the arc, and a further displacement of the torch is effected as far as a starting point on a third contour to be welded. The third contour is then done and so on, transfer from one contour to the other and adjustment of welding parameters is effected automatically until the last bead is made. The arc is then switched off.

Abstract: A method of continuous welding of a series of tubes to a tube sheet, in which the torch current is decreased to produce partial fading of the arc after completion of the first welding bead, and the torch is then moved to a starting position on a second contour to be welded. A stationary preheat is then effected, and a second weld bead is made by following the second contour to be welded. The process continues until the last bead has been made, whereupon the arc is switched off.

Abstract: PROCESO DE MONTAJE DE TUBOS (6) EN UN GENERADOR DE VAPOR. CONSISTE ESENCIALMENTE EN INTRODUCIR LOS TUBOS (6) POR CAPAS HORIZONTALES ( EL GENERADOR PUEDE ESTAR OCULTO DENTRO DE ESTE OBJETO), EN INSTALAR BARRAS ANTIVIBRATORIAS (10) SOBRE ESTAS CAPAS, EN DISPONER PESOS SOBRE ESTAS BARS (10) Y EN VERIFICAR LOS JUEGOS ENTRE LOS TUBOS (6) Y LAS BARRAS (10); LOS TUBOS (6), EXCEPTO TOLERANCIAS, PUEDEN SER REEMPLAZADAS. SE INTRODUCE A CONTINUACION LA CAPA DE TUBOS INMEDIATAMENTE SUPERIOR. EL CONJUNTO DEL PROCESO DE REPITE HASTA LA TOTAL COLOCACION DE LAS CAPAS. APLICACION EN LOS GENERADORES DE VAPOR DE CENTRALES NUCLEARES.
