Abstract
A process for the production of an acoustic treatment panel that includes an acoustically resistive layer (), at least one alveolar structure (), and a reflective layer (), as well as at least one channel that is bordered at least in part by a wall () that is secant with at least one wall of a cell of the alveolar structure (), includes elevating the temperature of the wall () and the ends of the cells of the alveolar structure () and injecting a pressurized gas into the channel () so as to expand the wall () of the channel so as to flatten it against the ends of the cells of the alveolar structure () in such a way as to produce a weld by continuous diffusion between the ends of the walls of the cells of the alveolar structure () and the wall () of the channel ().
