These observations were made during tiplife tests in spot welding mill finish aluminum alloys. Nugget-formation quality can be monitored effectively and nondestructively by use of a motion transducer. Interface dynamic-resistance can be monitored by electrode to electrode voltage drop. Cumulative deterioration of the electrodes can be measured semi-quantitatively by micrometric profile recording. These techniques permit short-run schedules for screening the effectiveness of surface treatments. It is also shown that nugget shear load can be estimated when gauge, nugget diameter, and ultimate tensile strength are know. (Becker)
