Abstract
A pulsed laser arc welding method and apparatus whereby a pulsed input laser beam is generated by a laser pulse generator to cause an ionized plasma cloud to be generated at a worksite. A power supply supplies energy to an arc welding device, which is stored in a capacitor therein. This energy is drawn out of the storage capacitor once the ionized plasma cloud is sufficiently conductive. Control circuitry is provided to control the pulse repetition frequency of the laser pulse generator and to control the energy dissipation from the storage capacitor in the arc welding device.
