Beschreibung
Zusammenfassung:	The invention concerns an assembly for controlling welds by ultrasound, comprising at least one annular multi-element probe (12) having longitudinal waves inclined at between 0 and 5°, comprising several concentric annular elements, and a linear multi-element probe (14) having transverse waves inclined at between 35 and 70°, comprising several straight elements parallel to each other. The annular probe (12) comprises a member for emitting waves at a frequency of between 5 and 15MHz and a means for focusing the acoustic energy emitted from the annular elements by electronically managing delay laws. The linear probe (14) comprises a member for emitting waves at a frequency of between 6 and 10MHz and a means for focusing the acoustic energy emitted from the straight elements by electronically managing delay laws.
