This paper describes the study on the relationship between mash seam welding variables and weld characteristics, and on the some physical and chemical properties of the weld in the mash seam welding of stainles steel 1mm thickness. That is to say, before an systematic experiment, some welds were made without taking data. Thereafter, among the welding condition, welding time and rest time were held constant, and welding current, welding pressure, initial over lap, and welding speed were varied, then breaking load, joint thickness and nugget penetration were measured. Also, corrosion resistance test, pressure test and bending test were accomplished. The results obtained are as follows; (1) If optimum welding conditions are selected and sheet thickness is comparatively thin, stainless steel sheet may be statisfactorily mash seam welded. (2) Welding current and initial over lap must be severely selected. (3) Electrode force must be very large. (4) Corrosion resistance of the weld joint is very good whicherer heat-treated or nonheat-treated. (5) Nugget formation is not along the faying surface but parallel to sheet surface.
