Proper Storage of Flux Coated 7018 Welding Rod

7018 welding rods allow very little hydrogen into the weld pool unless they have moisture in them from not being stored correctly. Moisture allows hydrogen into the flux, which is then introduced into the weld pool adversely. What happens is the moisture is superheated and then bubbles up to the surface leaving an open pocket in the finished weld bead. So at that spot the weld is weaker because it is not a solid bead.
