The purpose of this study is to evaluate the strength at spot welded region for the automotive thin plates and to find out the fracture region by a finite element method. spot welding against the thin plate of 0.8㎜, 1.0㎜, 1.2㎜ and 1.6㎜ was conducted under various welding currents. The weldability of spot welded region was dependent upon the thickness and welding current, Nugget diameter of the spot welded region was proportional to the applied current. Generally, Maximum load at spot welded region increased with the welding current. However, too high current was inappropriate in acquiring the better weldability because of the sputtering effect. It was verified through FEM analysis that fracture was initiated at boundary region between nugget and parent.
