At what temperature does CSA W59 require low-hydrogen electrodes to be held?

The correct choice is based on CSA W59 guidelines, which specify that low-hydrogen electrodes must be stored at a temperature of 120° Celsius. This storage temperature is crucial for maintaining the integrity of the electrodes, as low-hydrogen electrodes are sensitive to moisture, which can lead to hydrogen embrittlement in welded joints. By keeping the electrodes at this elevated temperature, any moisture is driven off, ensuring that the electrodes remain dry and effective for producing high-quality welds.

Storing low-hydrogen electrodes at the specified temperature helps to mitigate the risks associated with hydrogen in the welding process, particularly in critical applications where the quality and strength of the weld are essential. It’s important for welders to follow this guideline to achieve optimal results and comply with industry standards.
