Land
Land turns up in 2 fields: welding, electricians. Here is what it means to the people in each one.
Land in welding
Shop word for the flat root face left at the bottom of a bevel, called the root face in codes.
Unbeveled strip of the joint edge at the root, typically about 1/16 to 3/32 inch on pipe. Its thickness, together with the root opening, controls how the root penetrates: a heavy land needs more heat or a wider gap, while a knife edge burns through. Welders file or grind the land even all the way around before fit-up.
"Land's down to nothing on that side, knife-edged, tighten the gap or you'll blow through."
Land in electricians
To terminate a conductor on a breaker, lug, terminal or device.
Landing a wire means stripping it and securing it under its terminal: a breaker lug, a neutral bar, a device screw or a motor lead. Feeders are landed and torqued to the value on the equipment label, and on industrial work every landed wire is checked off against the drawings. The word marks the moment a circuit becomes connected, which is why 'don't land anything yet' is a common instruction while other trades are still working.
"Pull the feeders tonight but don't land them, the utility hasn't released the service yet."
