A steam turbine casing stiffening system is disclosed. The tool may also include a length of a second tubular conduit for positioning around the exterior of the housing to define an annular area relative to the first tubular conduit for deposit of a low temperature metal alloy therein. The PGS may be formed on a surface of the second substrate, or may be formed over the first semiconductor device\u2014for example, on a dielectric layer formed over the first semiconductor device.
