Harsh Welding environment

Fireworks aren’t the only thing to ooh and aah about – especially when exploring the ability of Northwire’s cable and wire to withstand the effects of weld flash and weld slag!

Weld Flash and Weld Slag

While not commonly understood, weld flash is the flash of light that occurs in welding when the arch from the electrodes touch the metal. Weld slag, on the other hand, is the name for the metal bits and pieces that come off the metal during the welding process.

Weld flash and weld slag are important considerations in cable assembly design for applications in welding, spot welding, or stick welding environments such as industrial manufacturing floors and robotics and process automations.

Engineering Ruggedized Cable for Harsh Welding Environments

When weld slag falls off during the welding process, cables and power cords within the welding environment must be tough enough to handle these hot chunks of metal. Quality cable materials and design prevent the cable from starting on fire, melting the cable jacket, exposing the underlying shields or conductors that would result in electrical problems. Quality cable materials and design allow the cable to be resilient through harsh and extreme conditions and easily wiped off for cleanliness.

Northwire cables are specially engineered to handle weld flash and weld slag using materials that are designed to withstand this harsh environment. TPE’s (thermal plastic elastomer), TPU’s (thermal plastic urethane), and specially formulated PVC are utilized within Northwire’s cable jacket to protect the integrity of the cable.
