Abstract: A method of automatically inspecting a weld bead deposited in a plurality of passes in a chamfer formed between two parts by performing the following steps: positioning at least one emission electromagnetic acoustic sensor on one side of the chamfer and at least one reception electromagnetic acoustic sensor on an opposite side of the chamfer, the ultrasound wave emission sensor being configured to emit Rayleigh surface waves; while depositing a pass, automatically moving the sensors to follow the movement of welding electrodes along the chamfer; activating the sensors while they are moving to enable the emission sensor to generate and emit Rayleigh waves towards the pass of the weld bead that is being deposited, the reception sensor receiving the ultrasound signals transmitted and/or reflected in said pass; and reiterating the operation for the entire pass of the weld bead.
