pba,
The Kruger flaps are not physically welded shut, but they are indeed inhibited. As far as I am aware, they still have to be maintained in a serviceable state, and are still part of the functional tests for the Flap/Slat and HLWSCU system, but are electrically inhibited afterwards.
The intake ramps on a GR Tornado are also inhibited, but this is carried out physically, with steel jury struts replacing the redundant actuators.
