Systems and methods for sealant layering

Abstract:

Systems and methods for applying sealant to a seam between a first work piece and a second work piece, including applying a fillet layer of the sealant to cover the seam, applying a first flaring layer of the sealant adjacent the fillet layer and contacting the fillet layer and the first work piece, applying a second flaring layer of the sealant that contacts the second work piece, and applying at least one filling layer of the sealant so that the filling layers of the sealant in combination contact each of the first flaring layer, the fillet layer, and the second flaring layer.
