1. A combustor liner comprising: a first annular band having forward and aft ends, said first annular band disposed about a central axis; and a second annular band having forward and aft ends, said second annular band disposed about said central axis and having a flange disposed in an overlapping relationship with said first annular band so as to define a circumferentially extending joint area; and a weld disposed in said joint area comprising a first circumferentially extending weld bead penetrating said first and second annular bands, and a second circumferentially extending weld bead penetrating said first and second annular bands and disposed adjacent to said first circumferentially extending weld bead, wherein at least a portion of said first and second weld beads overlap each other. 2. The combustor liner of claim 1 wherein said flange of said second annular band has a first length in an axial direction, and said weld has a second length in an axial direction, said second length being substantially equal to said first length. 3. The combustor liner of claim 1 further comprising additional annular bands disposed about said central axis, each of said additional annular bands being disposed in overlapping relationship with an adjacent annular band so as to create an additional circumferentially extending joint area, wherein a weld is disposed in each of said additional joint areas, each of said welds comprising first and second overlapping weld beads. 4. A combustor liner comprising: a first annular band having forward and aft ends and a ridge containing a plurality of cooling holes, said first annular band disposed about an axis; a second annular band having forward and aft ends and a ridge containing a plurality of cooling holes, said second annular band disposed about said axis and having a flange disposed in an overlapping relationship with said first annular band so as to define a circumferentially extending joint area; and a weld disposed in said joint area comprising a circumferentially extending weld bead penetrating said first and second annular bands, wherein said flange of said second annular band has a first length in an axial direction, and said weld has a second length in an axial direction, said second length being substantially equal to said first length. 5. The combustor liner of claim 4 further comprising additional annular bands disposed about said axis, each of said additional annular bands being disposed in overlapping relationship with an adjacent annular band so as to create additional circumferentially extending joint areas, wherein a weld is disposed in each of said additional joint areas, each of said welds comprising first and second overlapping weld beads.
