Spot welding of electrical distribution box box
Many low-end distribution boxes use spot welding technology. Only spot welding is carried out at the corners of the box every few centimeters, while the remaining seams are filled with sealant. This worker is using a foot-operated spot welder to join parts of an electrical distribution box. Electric current then creates heat. Spot welding (or resistance spot welding) is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. This step ensures the structural integrity of the enclosure by securely joining individual panels into a cohesive unit.
