What is one acceptable means of attaching test leads and bond cables when installing a resistance bond?

One acceptable means of attaching test leads and bond cables when installing a resistance bond is exothermic welding. This method involves a chemical reaction that generates intense heat, allowing metals to melt and fuse together. It is particularly effective for creating strong, durable connections that can withstand harsh environmental conditions and mechanical stress, making it ideal for pipeline applications where corrosion control is critical.

Exothermic welding provides a low-resistance connection that is integral to ensuring that the electrical continuity necessary for corrosion control systems is achieved. This method is widely utilized in grounding and bonding applications across various industries, including pipelines, because it enhances the reliability of the bond over time, reducing the likelihood of failure due to corrosion or mechanical damage.

In contrast, other methods such as plastic fusion and epoxy bonding may not provide the same level of durability and electrical performance required for resistance bonds in pipeline corrosion control. Pit brazing, while effective for certain metal joining applications, is not as commonly employed for attaching test leads and bond cables as exothermic welding is.
