At what temperature are low hydrogen rods typically stored?

Low hydrogen rods are typically stored at a temperature of 250 °F to prevent moisture absorption and maintain their effectiveness. These rods are designed to minimize the potential for hydrogen embrittlement in steel welds, which can occur when moisture is present in the welding environment. Storing them at 250 °F ensures that any moisture is eliminated and that the hydrogen content within the coating remains low, which is crucial for weld integrity.

The standards set forth in the Structural Welding Code emphasize the importance of maintaining proper storage conditions to enhance weld quality and prevent defects. Conditions that involve higher or lower temperatures than the specified 250 °F may not provide the same level of protection against moisture, increasing the likelihood of weld weakness or failure. Therefore, adhering to this guideline is essential for welders to ensure durable and reliable welds when using low hydrogen rods.
