    7014 rods

    I recently ordered a 10 lb box of 3/32 7014 rod, it came in a plastic box, the box was sealed with heavy plastic, I cut it open and removed the tape around the seam, popped the top off and the rod was sealed in plastic and wrapped in heavy paper like shirt cardboard, thought it was odd, as I thought 14 was not affected by moisture. The instructions gave very specific instructions on how to dry it, I think it was 30 minutes at 350*. Just curious if any of y'all had seen this before. I've bought 7018 that wasn't wrapped as good.

    7014 does not need to heated

    LOW HYDROGEN like 7018 does need to be heated to 250°F. When using 7018 I heat over night. Typically when you using LOW HYDROGEN rod like 7018 some one may X-ray the weld and look for bubbles in weld.
    The last thing is have redo all your welds for that job.

    The LOW HYDROGEN rod will also weld better with per heating.

    Re: 7014 rods

    The rod is LIBERTY brand, instructions say "Redrying instructions 176* F for 30 minutes". I was surprised when I got it, the way it was wrapped was crazy, I think the paper in the plastic box is like a desiccant. Makes me wonder if it's some kind of chinese recipe in the coating. It ran very nice on the new carport.I'm in southern Arizona, so I doubt it would ever be an issue anyway, I never dry my 7018.

    I wonder why Lincoln has drying instructions for 7014?

    If you just doing shop it need to per heat 7018.
    If making a living from and need to comply with codes you do need to per heat.

    My rod is LIBERTY, is LINCOLN specifying to dry 7014 too?

    See link for Lincoln drying specs for many rods.

    Re: 7014 rods

    I think people are confusing keeping low hydrogen rods dry, so they perform correctly, with "redrying" rods which may have gotten wet or been exposed to humid conditions too long.

    Wet rods of any type may not perform correctly hence the instructions for "redrying" rods of many types.

    Re: 7014 rods

    1) if rods were soaking wet and got rusty i would not use
    .
    2) rutile rods 6013, 7014, 7024 often have some cellulose mixed in which has water in it and cause its often paper based it will burn if in oven at too high a temp. thus why drying might say under 200F to avoid burning it. usually dont worry about drying rutile rods, if they were soaking wet i would throw them away
    .
    3) 7018 lime rods chemically absorb water like cement or concrete you can heat to 300F for decades or centuries and the water will never come out. usually have to heat to over 750F to remove chemically combined water. most professionals if rod wasnt kept in "dry" rod oven at 200F to keep it from absorbing water out of the air after 4 to 8 hours throw the rod out or use only for less sensitive non structural code work. if "wet" 7018 put in a "dry" rod oven at 200F it will never remove the chemically combined water any more than concrete heated to 200F would turn to a powder after exposure to 200F

    Not sure on the AWS requirements for low hydrogen electrode storage temps but CSA W48 requires low hydrogen electrodes be stored at 250f.

    That true with all Welding rods.
    Low hydrogen has more spec for being dry. It may have x-ray and the hydrogen will put bubbles in weld

    I keep some 3/32 7014 electrodes around for when my kids want to do some welding. The 7014 strikes and restrikes so easy for them. It’s much better for the kids than 7018 is.
