摘要: Abstract In this work, samples of aluminium alloys 5083-T0 and 6082-T6 have been welded under conduction regime, using a high power diode laser. The influence experimental variables, as the laser linear welding rate, on sizes properties butt weld beads has studied. addition to measure depths widths beads, their microstructure, microhardness profile corrosion resistance analysed. results obtained allow one define conditions leading good quality welds with higher penetration than those published in recent literature regime. Maximum values 3 2.3 mm were for 5083 6082, respectively. Additionally, simple mathematical expression relating depth ( d ) P processing rate v proposed: = − b ′ / , being ′, constant each alloy employed conditions. these coefficients estimated from fitting 6082 generated
