Hello Everyone!
I recall, clearly, my welding instructor discuss drying 7018 rods that had been “sitting out” before using them. Well, I never had an issue with 7018 rods until yesterday. Every stick I tried to use, I ended up with porosity at in the bead. I didn’t have time to cook them for a few hours, so I moved to 7014 for the remainder of the day.
I have seen posts on here talking about moisture not being a big deal unless your work is being done under a WPS and inspected, but I don’t like porosity in anything I weld... important or not. So my question is, can air humidity really cause that much of a problem, and if it can, where do you store your rods if you don’t have an oven?? I have a large toaster oven can bake a few lbs in if necessary, but I’d like to just keep them dry from the get-go. I have also seen the same issue with flux-core wire in my MIG machine.
Just wanting some ideas, so that I don’t have to buy a really expensive oven for a home shop.
Thanks!!
