Which clause number in AWS D1.1 2010 is titled 'Fabrication'?

• A. Clause 2
• B. Clause 4
• C. Clause 5
• D. Clause 8

Answer: (C)

The question tests knowing where AWS D1.1 2010 places the requirements for preparing and assembling components before welding. Fabrication is the section that covers how parts are cut, formed, laid out, and joined in prep for welding, including fit-up, alignment, distortion control, tack welding, temporary supports, and the sequencing of steps. Because the topic asked is exactly the one titled Fabrication, that clause is the correct reference in the 2010 edition. Other clauses deal with different parts of the project—design, welding processes, erection, inspections—and don’t address the preparation and assembly work that Fabrication governs.
