6061? What condition? T6? If so when welding it, expect it to lose approximately 1/2 it's yield strength around the welds. At worse expect it to lose 4/5th's of it's yield strength since it can and does return to the annealed condition (i.e. T0). It can be worked around but you have to incorporate that work around into your design. 5000 series don't lose as much strength when welding but they do lose some also.
3003 will also lose strength when welding too. And depending upon the initial temper of the material you purchase it can lose as much as 80% of it's strength.
