Welding of aluminium alloys with a high power Nd:YAG Laser

A report on the welding of aluminium alloys EN AW-1060 and EN AW-6082 with high power Nd:YAG laser is presented. Laser and process parameters were explored. Metalographic analysis was done to asses weld quality on selected samples.Consequently it is concluded that a 2000 W class Nd:YAG laser is appropriate for welding of thin sheets of aluminium alloys.
