A wind turbine blade includes a first shell member including a first mating surface along a first edge of the wind turbine blade. Also, the wind turbine blade includes a second shell member including a second mating surface along the first edge of the wind turbine blade, wherein the second mating surface is opposite to the first mating surface. Further, the wind turbine blade includes a bonding material disposed between the first mating surface and the second mating surface and configured to bond the first mating surface to the second mating surface. Moreover, the wind turbine blade includes a constrainer positioned at a desired bond line and coupled to one of the first mating surface and the second mating surface, wherein the constrainer is configured to restrict the bonding material from migrating into an interior cavity of the wind turbine blade.
