Laser Welding Aluminium Alloy 5083

This results in shallow welds with a low aspect ratio.

Laser welding aluminium alloy 5083.

Conduction welds are usually produced using low power focused laser beams. Laser welding of aluminium alloy 5083 p okon g dearden k watkins m sharp p french laser group department of engineering university of liverpool brownlow street liverpool l69 3gh united kingdom lairdside laser engineering centre birkenhead wirral united kingdom abstract there are two laser welding mechanisms keyhole mode and conduction mode. In this work high power co2 and yag lasers have been used to. The influence of experimental variables as the laser power and the linear welding rate on the sizes and properties of the butt weld beads has been studied.

Typical fusion zone configuration of aa5083 aluminum alloy welded using 4 kw laser power and 6 m min welding speed at two different defocusing distancesisshown in figure 8. In this work samples of aluminium alloys 5083 t0 and 6082 t6 have been welded under conduction regime using a high power diode laser. Aa5083 is strengthened by a solid solution of magnesium in the aluminum matrix as most of 5000 series alloys. The material for experimental welding was non heat treatable wrought aluminum alloy 5083 o o designates annealed state heat treatment method of thickness of 5 mm.
