When making spot welds in aluminum sheet, the welder has to consider the metal's density, strength, and protective film of aluminum oxide. The authors have made some observations that should help future investigators. Employing these observations, the welding engineer can determine the size and strength of a nugget needed for a job. They also help in setting up short-run welding tests to evaluate the merits of different electrodes and surface treatments.
