Application

This procedure defines the acceptance test for Flow Drill Screw (FDS) schedule development for aluminum, low carbon steel sheet and extrusions. All such sheet material must pass minimum performance testing. Consult the appropriate Engineering Material Specification for material exceptions. Testing confirms that the correct screw and processing parameters were used to satisfactorily join materials together. Cross sections of the FDS joint must be evaluated to insure a robust joint. After the correct tooling has been identified, lap shear and coach peel samples are fabricated. Initial testing requires a sample size of 30 each for the strength tests. Samples are pulled on a tensile test machine.
