What is one requirement for proper storage of welding rods?

One of the critical requirements for the proper storage of welding rods is that they must be kept dry and free of moisture. Moisture can significantly affect the performance and quality of welding rods. When exposed to humidity, the rods can become contaminated with rust or other chemicals that may cause defects in the weld, such as porosity or lack of fusion. Keeping the rods dry ensures that they maintain their integrity and can produce high-quality welds.

Additionally, storing welding rods in direct sunlight or in conditions where they are exposed to air can also lead to degradation. Sunlight can cause some types of welding rods to degrade or lose their effectiveness over time. Hence, ensuring they are stored in a controlled environment, where moisture is minimized, helps protect their properties. Frequent monitoring of humidity is also important but should be part of a broader strategy rather than a standalone requirement.
