Abstract:
Experimental results are reported for laser-induced annealing, surface alloying of steel and welding of polymer sheets. The laser beam was shaped by a focusator into an irradiant straight line of constant thickness. An industrial CW C02 laser LATUS-31 was operated in either single mode or multimode lasing regimes. Processing with focusator-shaped beams considerably improved the operating characteristics of laser treated details, improved the productivity and cut down the cost of materials.
