This research is focused on characterizing electrical contact resistance involved in resistance spot welding of thin sheet steels. It is part of a larger study in which a mathematical simulation of the welding process is being developed. A special test fixture has been fabricated that allows contact resistance at the electrode-to-sheet interface and the sheet-to-sheet interface to be measured under typical welding pressures (e.g., 14 ksi) and from room temperature to elevated temperatures. Bare and galvanized mild and HSLA steels have been considered. The nature of the contact resistance is discussed, and experimental findings are presented
