In a method for reducing “blow-out” of annular welds for attaching components in a fuel injector, a relief region is formed on radially-facing surfaces of the components. The relief region is adjacent to a press-fit region. The components are then pressed together, and a weld is made in the relief region. A sealed gap is thereby formed in the relief region between the weld and the press-fit region. The sealed gap provides for the expansion of trapped gases that could otherwise “blow out” the liquid weld bead.
