For everyone involved in any phase of welding steel structures – engineers, detailers, fabricators, erectors, inspectors, etc. – the new D1.1 spells out the requirements for design, procedures, qualification, fabrication, inspection, and repair of pipe, plate, and structural shapes that are subject to either static or cyclical stresses. D1.1 includes:

• Design of tubular and nontubular welded connections.

• Prequalification of welding procedures.

• Qualification of new procedures and personnel.

• Fabrication requirements, including base metals, consumables, and tolerances.

• Inspection requirements and acceptance criteria for various examination methods.

• Stud welding design, production, and inspection requirements .

• Strengthening and repair of existing structures.

• An extensive commentary annex that provides timesaving interpretation.

• Dozens of valuable reference tables, charts, and forms. U.S. Customary and SI units of measurement. 562 pages, 22 annexes, 170 figures, 75 tables, (2008).
