  • Effect of Force Control during Spot Welding on Weld .

    force profiles. Decreasing the electrode force during welding facilitates the initiation of spot weld growth earlier in the weld cycle which in turn produces bigger weld diameter and stronger weld strength. The opposite was noticed when electrode force was increased during the weld cycle. Furthermore decreasing the electrode fore during welding produced a button pull-out failure and increasing the force produced .
