Standard Practice for Acoustic Emission Monitoring During Resistance Spot-Welding

Importancia y uso:

5.1 The AE produced during the production of a spot-weld can be related to weld quality parameters such as the strength and size of the nugget, the amount of expulsion, and the amount of cracking. Therefore, in-process AE monitoring can be used both as an examination method, and as a means for providing feedback control.
