    Default Welding on Sucker Rod

    I built a pipe fence a few years back with some sucker rod horizontals. I remember I couldn't weld it with DC due to it being magnetized. I set my welder to AC and got it glued together, but some of the welds weren't very strong.

    Anyway, I'm comtemplating using some sucker rod for my upcoming corral project. I plan on unsing AC/6011 for the sucker rod with my TB302. Is this the typical practice for working with sucker rod or is there something else I should know?

    Thanks

    why is it magnitized ?? done on purpose or just ends up that way?? can you de-magnatize it ???
    thanks for the help
    ......or..........
    hope i helped

    feel free to shoot me an e-mail direct i have time to chat. james@newyorkmetalart.com

    I believe anytime you move a piece of metal back-and-forth thousands of times in close proximity to another piece of metal, you will end up with magentism.

    Pre-heat might eliminate the magnetism, no garuntee though. Another tecnique is to wrap your ground cable around the pipe in close proximity to the weld. It creates an induction magnet that will eliminate the opposing magnetic force. Once again no garuntees it will work. It's used quite a bit by pile drivers since the tops of the piles often build up magnitism. I'd say try it, if it doesn't work keep using AC. It may be a pain in the but to do but it sure beats using an AC arc if it works.

    If it is short lengths you can wrap some copper wire around it and use a
    12v battery hold one end of wire to - post and just ark other end to + post
    you can mag and demag small objects like this. But try at own risk I have never had a problem but anything can happen. Or if you have a local tool or die shop around they all have demags.

    I have used the ground induction coil to good success 5-7 wraps trick is to wrap in the correct direction.

    Well I have to admit it's been a long time since I stick welded stuff but my recollection is 6011 on AC should do a fine job on a fence project. Save you a lot of time not having to mess with demagnetizing all of it.

    Another choice would be 7014 on AC if the metal is not too rusty/dirty.

    Here's link that was shared on another web site, you might find interesting. Spec's on sucker rod most is chome moly So low hydrogen rod might work better. Just a thought.
