Rohn Tower Leg Repair
This tower top section was stored on the ground for a while with the top lower than the bottom. It collected water in the leg that ran to the bend in the leg and when it froze, it split the leg. These pictures show how I repaired the leg.
 
Here I am cleaning the zinc from around the split.
 
I tapped the split closed a little bit before starting the weld. Here Gordon, N4LR, gets into the attack.
 
Time to get ready to weld...
 
TIG welding the split. I used a 308L stainless filler rod for the repair.
