The main wage for ornamental ironworkers ranges from $20.89 per hour to $45.00 per hour. The wages are adjusted according to the location of the work and the nature of the work. The main tool of the ornamental ironworker is an arc welder. Welding and burning equipment are considered "tools of the trade.”
Arc welding power supplies can deliver either direct (DC) or alternating (AC) current to the work, while consumable or non-consumable electrodes are used. The welding area is usually protected by some type of shielding gas (e.g. an inert gas), vapor, or slag. Arc welding processes may be manual, semi-automatic, or fully automated.
