Typically the sheets are in the 0.5 to 3 mm (0. 020 to 0.118 in) thickness range.

During spot welding we don't need to weld less than 3d distance, where d= diameter of spot welding rod.

The spacing between two spot welds should not be less than 3d in order to avoid shunting effect between neighbouring welds.

Current always tries to pass through the low resistance path. If the distance between the two spot welds is less the current pass (max amount) through the previous weld as its resistance is less leading to poor weld quality of the second weld.
