ABSTRACT:
A method for producing a spinning box frame for an open-end spinning machine wherein lateral elements (2, 3) of a spinning box frame (1) are connected with interposed bracing elements (4, 5, 6) by means of a welding process which substantially prevents the occurrence of heat distortion tensions. The bracing elements (4, 5, 6) are joined by means of a laser welding process, preferably with a CO.sub.2 laser, squarely on the interior wall (20) of the lateral elements (2, 3). The components (2 to 6) of the spinning box frame (1) are fixed in place in a welding device (26), which permits the exact positioning of the individual components during the laser welding process.
