1. A stator vane for a gas turbine engine combustor comprising:
a vane segment comprising:
a vane having a leading edge, a trailing edge, a suction side, a pressure side,
a vane inner base, and a vane outer base;
an inner shroud segment attached to the vane at the vane inner base; and
an outer shroud segment attached to the vane at the vane outer base;
a support structure attached to the vane at a vane trailing edge; and
a first weld shield attached to the support structure by a first connector, wherein the first weld shield is positioned over and spaced away from the suction side,
wherein the vane, inner shroud segment, outer shroud segment, support structure, and first weld shield are integrally formed during a single, continuous additive manufacturing process.
