A control system (12) and method for inspection of parts is particularly adapted for inspecting resistance welded parts in a production line (14) environment. A displacement sensor (24) is coupled to a welding electrode for generating a displacement sensor signal responsive to the displacement of the welding electrode during welding. A test computer (26) evaluates the displacement sensor (24) signal to identify defective parts and to provide a fault signal. A part containment box (44) receives the improperly welded parts and has an input sensor (46) for generating a signal when an improperly welded part is deposited therein. The test computer (26) is operative to disable the production line (14) and prevent the indexing part until the deflective part has been removed from the producion line (14) and deposited into the part containment box (44) which generates the input sensor signal, thereby enabling the production line (14).
