A magnetic pulse welding operation is performed to secure first and second metallic components together, such as a yoke and a driveshaft tube in a vehicular driveshaft assembly. The yoke includes a first portion, such as a body portion, and a second portion, such as a pair of opposed yoke arms, that are separated by a bridge portion. The end of the driveshaft tube is disposed co-axially about the body portion of the yoke, and a magnetic pulse welding operation is performed to secure the end of the driveshaft tube to the body portion of the yoke. The bridge portion can be defined by a groove formed in either the outer surface or the inner surface of the yoke. The groove may have side portions that extend either generally perpendicular or are angled or tapered relative to an axis of rotation of the yoke. If desired, a pair of opposed, semi-circular grooves may be formed in the yoke to define the bridge portion. The bridge portion allows the yoke arms to be elastically deformed and can also limit the propagation of shock waves through the yoke that can result from the performance of the magnetic pulse welding operation.
