Abstract
Nowadays, there is an increasing demand for AISI 316 stainless steel for automotive, medical, aerospace, for tool manufacturing and for nuclear industry. Compared with continuous beam laser welding, pulse temporal shape, pulse duration and the repetition rate are fundamental parameters that have a direct influence on the quality on the welded joint [2]. The laser welding of AISI 316 stainless steel thin sheets by millisecond pulsed laser will be analysed within this research by addressing to pulsed laser parameters influence on the geometry and appearing of the welding joint. The influence of laser power, pulse duration and repetition rate were determined by tracking fusion lines on specimen’s plates and butt weld stainless steel welding were obtained by using the determined optimal welding parameters. All the parameters have a major influence on the geometrical appearance of the weld bead.
