Aerospace AA2xxx and AA7xxx alloys have good mechanical properties such as high strength-to-weight ratio, fatigue- and corrosion resistance. These alloys are known for poor weldability with traditional fusion welding techniques due to hot cracking sensitivity and large heat affected zone with reduced mechanical properties. This paper describes laser welding of AA2065 and AA7021 alloys applying a purpose made wire for added weld material. The welding was made in a laser metal deposition machine with wire feeding and Argon shield gas. The work demonstrates promising results for joining of these alloys with added material, showing weld strength similar to base material. Porosity is, however, still a challenge that must be controlled by optimizing the welding process.
