WebShunting effect of resistance spot welding is evaluated based on the electrode displacement signals. The shunted welds in mild steel with different weld spacing were produced. The results showed that the weld spacing and nugget diameter were polynomial-correlated, and the minimum welding spacing of 20 mm can be derived from the results. WebShunting in resistance spot welding is the diversion of the weld-ing current from the weld to be made to a nearby existing weld (Ref. 1). If a significant proportion of welding current flows through the previously made weld, the heat generated may not be
