    Default Fence post repair question...

    I'm a new owner of a Millermatic 211 and my first order of business is to repair my pool fencing.

    The fencing itself consists of 2x2 posts that are powdercoated. Due to drainage issues, many of the posts rotted off at ground level.

    Rather than replace the entire post (each cross bar is welded to it in several places and the caps are also welded on), I plan to cut off the rot at the bottom and butt-weld some new 2x2 post onto it to lengthen it.

    The plan of attack is to use .030 wire w/C25 gas.

    Besides grinding off the powdercoating and any galvanized surfaces, are there any precautions or tips you guys can provide?

    It's only 16ga steel. Should I butt weld them with a small gap or just butt them up tight and let it penetrate? I'm not worried about looks - this part will be buried in concrete. Also, I don't think it's completely necessary but I have considered using some fish plates as well.

    Any advice you guys/gals can offer will be absorbed readily.

    Thanks!

    Cool

    Sounds like you have a good plan. I would do a small gap like a 16th..Bob

    It sounds like a good plan, unfortunately it wont work. There wont be anything to weld to at the bottom. It is best to replace the post and use heavier gauge tubing as well as pipe wrap tape on the bottom. Just cut them off with a zip wheel, it only takes a few minutes.

    I agree...

    was thinking you might look at weld tabs and baseplates from the Kingmetals catalog..

    http://www.kingmetalscatalog.com/lg_..._2013/page/252

    baseplates can be welded to the repaired/replaced post tube.. then secured to the concrete with Hilti Bolts or similar....

    Could you post a picture please, that will help make a judgment. How far does the heavy rust go up the inside of tube? You said they will be covered in concrete, does that mean you plan to core drill on re installation ? If so I say weld plates and redhead them down.

    Why Not..??

    The way I understood it.. was to cut off a rotted out section of 2X2 tubing and weld in a sound new piece of the same length... Restoring the 2X2 post to original length...

    Another plan of attack could be to use 2.5x2.5x3/16 or 1/4" tubing and slide it over the outside of the 2x2 and weld it. Go several inches above where you cut it off. If the 2.5" tubing goes up high enough on the 2", then the welding is more to seal out moisture but does add rigidity.
