Correlating variations in the dynamic resistance signature to weld strength in resistance spot welding using principal component analysis

Adams, David W.; Summerville, Cameron D. E.; Voss, Brendan M.; Jeswiet, Jack; Doolan, Matthew C.


Traditional quality control of resistance spot welds by analysis of the dynamic resistance signature (DRS) relies on manual feature selection to reduce the dimensionality prior to analysis. Manually selected features of the DRS may contain information that is not directly correlated to strength, reducing the accuracy of any classification performed. In this paper, correlations between the DRS and weld strength are automatically detected by calculating correlation coefficients between weld...[Show more]
