ABSTRACT:
A suitable diffusion nozzle (20) for an ultrasounds probe using water as coupling agent between a piece under inspection and an acoustic transductor (13) such that the water is driven towards the surface of the material through a propulsion channel (21) surrounded by a plurality of diffusion channels (23) through which air is injected under pressure, forming an insulating screen capable of repelling the drops of water generated on the jet of water striking the surface of the material.
