Standard Practice for Acoustic Emission Monitoring During Resistance Spot-Welding

2017-08-16 /Historical
Superseeded by:

1.1 This practice describes procedures for the measurement, processing, and interpretation of the acoustic emission (AE) response associated with selected stages of the resistance spot-welding process.

1.2 This practice also provides guidelines for feedback control by utilizing the measured AE response signals during the spot-welding process.

1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
