<p>The invention relates mainly to a method of assembling a tube (7) of inside diameter Di and a sheet (1) of thickness Et having at least one substantially planar portion involving steps whereby the tube is positioned level with the substantially planar portion of the sheet, the end section of the tube being at least partially in contact with the sheet, then the sheet is assembled with the tube by flow drilling the sheet using a drill bit (2) of a diameter greater than or equal to Di - 2 x Et, the flow drilling being performed from the sheet towards the tube, along the axis of the tube. The invention also relates to the assembly of a tube and of a sheet and to the use of the method for the manufacture of solar absorbers.</p> |
