I made a "T"-shaped rebar bender by welding a short section of 3/4" steel pipe to a 3/4" pipe handle (the short piece had an inner 1/2" pipe sleeve, welded at each end to the 3/4", with a 1/2" slot along one side).
The weld broke after about three months and several hundred rebar bends. The original weld was TIG-welded. I made a quick repair using an oxy-acetylene torch, melting the broken weld back together but not using any rod, and it lasted one day before it broke again! I used a big tip and a lot of heat to get the weld done quick. The flame was just a bit excess acetylene, the way I normally weld, but something went wrong. Any ideas?
