![]() ![]() An actuation system directs the laser radiation to the projection and contacts the projection with a laser head based on forced control signals. The laser joining system has a laser system for generating a predetermined level of laser radiation based on radiation control signals. The converter exhibits substantially even temperatures and a vibrational node within the spacer.Ībstract: A laser joining system deforms a workpiece projection based on collapse of the projection to a predetermined displacement. ![]() The spacer, back driver, and front driver masses are provided with fins to radiate heat from the converter. The front and back ceramic stacks are of a suitable piezoelectric ceramic material such that when energized with alternating electrical power from the power supply the piezoelectric material renders the converter resonant at the predetermined frequency. The converter has a metal front driver mass, a metal back driver mass, a front ceramic stack, a back ceramic stack, a spacer between said front and back ceramic stacks, and a fastener extending axially of the converter coupling the front and back drivers masses to clamp the ceramic stacks and the spacer between the front and back drivers. The converter is supplied with alternating electrical power from a power supply. Abstract: An electroacoustic converter is disclosed for converting electrical energy into mechanical vibrations at a predetermined frequency. ![]()
