subject: Metal Fabrication techniques [print this page] Structural fabrication is for construction of buildings and bridges. Skills for welders are regulated by the American Welding Society. The skills and practices used in steel construction are defined by the AISC or the American Institute of Steel Construction. Cutting torches and abrasive wheels are used most commonly in the fabrication industry because they are easy to use and transport. Plasma tables, laser cutters, water jet beds, and other types of stationary equipment are much less common, but can produce impressive results with incredible tolerances. Computer based equipments like Computer Numerical Control Punch Press or Computer Numerical Control Lasers may also be used.
