Structure of sheets assembled by dimpling and method for assembling such a structure

摘要

The structure has a first sheet (1) including an edge (2) provided with a series of tenons (4a-4e) corresponding to housing recesses of a second sheet (5), where welding is performed at an upper surface of the second sheet. Each tenon has length different from length of the other tenons, where difference in height between the tenons is greater than thickness of the second sheet. The first sheet is plain or non-plain. The tenons are leveled to not exceed a lower surface (6) of the second sheet after welding of the first sheet on the second sheet. An independent claim is also included for a method for assembling a sheet structure.
