Process for manufacturing a weld connection between two inserted hollow profiles using a pressure device for suppressing the existing gap before the welding ; corresponding pressure device

摘要

The method involves inserting a hollow profile (3) into a recess of another hollow profile (5), and arranging a pressure device between areas of the profile (3). The device is activated for producing a null gap between the areas and the recess and less than 1 millimeter. The device is stopped when the gap is sufficient for a weld connection, and a welding or soldering procedure is implemented along the gap for connecting the profiles. Independent claims are also included for the following: (A) a frame structure or frame part for a frame of a motor vehicle; and (B) a pressure device for executing a method for manufacturing a weld connection.
