Oh that’s ok. The connectors I was referring to are the guys that work with the crane hoisting beams, columns, joists etc into place. They’re in what’s called a “Raising Gang” which is usually made up of 6 people. A foreman, a crane operator, two guys on the ground sending the pieces up, and two guys in the air.

Welding is fusing two metals together, we typically use welding rods or a wire feed machine. For the points I had to weld, I used the wire feed machine because it’s much faster than using welding rods.
