Thread: First Project - Trampoline Poles

  1. Default First Project - Trampoline Poles

    I just got my new welder (161STH) and had a my first potential job. Earlier this winter, my kids trampoline became a kite and bent or snapped 4 of the poles that hold the netting around the top. I looked at just buying some new legs and realized I may as well buy a new trampoline for what they wanted. I was able to straighten some of them out just putting them into the press, but had two that were extremely mangled right where the round tube is formed down to a square to slide into the trampoline. It is some odd sided galvanized pipe. Please keep in mind I have zero fabricating experience let alone welding, so I am sure there was a MUCH better way to do this job.

    Long story short, I bought some 1/2" flat stock and attempted to use it to fuse around all of the rips and dents. I have no gas so this was done with the stick welder. 6011, 40amps, hint of hot start and 60% arc force. I tried 6013 but it wasn't working as good on DCEP. After watching some youtube videos from and weldingtipsandtricks, I tried DCEN which laid down more material but didn't seem to fuse the metal at my settings. I stuck with the 6011 after a bit of fiddling around. I realized that this was not the best process here after the first time I lit up and saw it blow through the pipe instantly. I practiced a bit until I could do it with minimal issues and then welded the two legs back together. The tear was directly where the pipe had been formed into a square that slides down into the trampoline so I didn't see how I could cut out any bad spots. I basically filled in the craters, tears and built up around the flat stock. They look horrendous, but they are back together and I didn't spend 160$ for new poles. Now for a light coat of paint and reinstall them on the back side of the trampoline so no one has to see them.

    It's probably galvanized, and welding it will also make you sick from metal fume fever.

    I did take a flap disc and get the area down to bare metal first. So far so good. I know that the fumes from this stuff were made out to be a pretty serious deal from the one day course I took so I also did it with a good respirator on. The trampoline is 100% back together and bounce tested and my patch to the jumping mat is also holding.

    Flap disks are no good for this. They tend to polish more than remove metal. Use hard stones only.
