6.2.1
The thermal cutting of structural steel by hand-guided or mechanically guided means is permitted.
6.2.2
Surfaces that are specified as “finished” in the contract documents shall have a roughness height value measured in accordance with ASME B46.1 that is equal to or less than 500 μin. (12.5 μm). The use of any fabricating technique that produces such a finish is permitted.
Commentary
Most cutting processes, including friction sawing and cold sawing, and milling processes meet a surface roughness limitation of 500 μin. (12.5 μm) per ASME B46.1.
