WebResistance Spot Welding (RSW) is an important welding technology for joining two or more metals in various manufacturing industries. For instance, to date a car may contain an … WebYes, there is a minimum spacing for spot welds listed in most sample weld schedules. If welds are placed too close together, the weld current can flow through/across the sheet of metal between the desired weld and previous weld locations as shown. This current does not flow through the desired weld joint and therefore does not help create a nugget.
