In what American City and State was the world's largest welding machine unveiled?

When NASA revealed the largest welding machine ever built in 2014, it did so in the Big Easy. The assembly building is over 200 feet high and is intended to build the first deep-space rocket. The rocket is expected to be ready for its first test launch sometime in 2018. It won't be taking humans into space the first time but rather an experimental capsule.
