What welding process can the GEC be spliced by?

The correct answer is exothermic welding, which is a process that uses a chemical reaction to generate heat for the welding operation. This method is particularly effective for splicing the Grounding Electrode Conductor (GEC), as it creates a strong and durable bond between metals, making it ideal for grounding applications where low resistance joints are necessary.

Exothermic welding involves mixing powdered metal components, such as copper and aluminum, that ignite and create molten metal which then fuses the connecting parts together upon cooling. This process is advantageous for electrical connections because it produces a joint that is not only robust under mechanical stress but also maintains excellent conductivity.

Other welding processes, while useful for various applications, do not provide the same efficiency or effectiveness when it comes to splicing a GEC. Resistance welding, for example, uses heat generated from electrical resistance to join materials, which may not be suitable for the specific requirements of grounding systems. Similarly, arc welding and gas welding are methods that typically require a filler material and may not ensure the same level of integrity for electrical connections as achieved through exothermic welding. Thus, exothermic welding stands out as the preferred method for splicing a GEC due to its ability to ensure a reliable and electrically conductive joint
