ABSTRACT:
A method for securing components of a vehicular driveshaft includes disposing a neck of an end fitting into the open end of a driveshaft tube. The end fitting is held with respect to the driveshaft tube so that an annular gap is formed between the neck and the driveshaft tube. An inductor is provided about the driveshaft tube adjacent the end receiving the neck. The inductor is energized to generate a magnetic field for collapsing the driveshaft tube about the neck at a high velocity so that the driveshaft tube and the end fitting are welded to each other.
