if it's heat treated (6000 series?), you have to do another heat treatment after the repair. That's what makes it difficult for most welders. They can weld, but cannot do the heat treatment.
If it's not heat treated (7000 series?), it should be not too difficult for someone experienced in welding alu.
Depends on the type of aluminium alloy used.
