Prediction of electron beam weld quality from weld bead surface using clustering and support vector regression

作者:

Highlights:

• Proposes a quality predictive model for EBW process using weld surface attributes.

• Varying weld surface profiles have good correlation with mechanical properties.

• Develops a predictive model for surface attributes using SVR.

• FCM and DBSCAN cluster the weld joint into poor, fair and good weld.

• Avoids time-consuming trial-error, conventional nondestructive testing methods.
