Abstract

Laser beam penetrations have been carried out on URANUS 45 duplex stainless steel sheets, varying the beam power as well as the traverse speed. The microstructural results, in terms of bead geometry, microhardness, and austenite content, have been related to the working parameters, with the support of an analytical thermal model of laser beam welding.
