wires were joined to the copper clamps attached to the workpiece by mechanical
fastening. The workpiece specimens were held in a vice for welding, and the vice
was electrically insulated from the workpiece.
The forces involved during the process were measured using a 6-axis Kistler
force dynamometer. The force dynamometer was attached to the vice holding the
workpiece. A sampling frequency of 3,000 Hz was used to record the process results.
To begin the weld, a hole is drilled into the workpiece to minimize the forces of
plunging on the tool. The drilling operation is performed on the same conventional
