Paper Abstract

Although the pulsed YAG laser has distinct advantages as a precision welding tool, limited power and pulse rate capability has restricted its applications. A 500 Watt average power, 300 pulse per second system is described which makes possible conduction seam welding penetrations as great as .06 inch and welding speeds as high as 150 inches per minute. Penetrations and welding efficiencies for pulsed YAG are compared to published data for CO2 and CW YAG lasers. Penetration and welding efficiencies are substantially higher for pulsed YAG up to speeds of 120 inches per minute. YAG laser penetration welds are reported for the first time. Hermetic seal conduction laser welds are also reported for the first time.
