What's in D1.1? For everyone involved in any phase of welding steel structures - engineers, detailers, fabricators, erectors, inspectors, etc. - the new 540-page edition of D1.1 spells out the requirements for design, procedures, qualification, fabrication, inspection, and repair. A wide range of projects, repairs, and product forms come under its authority, including pipe, plate, and structural shapes that are subject to either static or cyclical stresses.

The AWS D1.1/D1.1M 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 time-saving interpretation
• Dozens of valuable reference tables, charts, and forms
• And much more

That's why D1.1 has been mandated by local, state, and overseas codes, approved by ANSI, adopted by the Defense Department, preferred by NASA, and required by contracts for countless industrial and construction applications.

What's new in this edition?

Improvements and additions to the previos edition of D1.1 are underlined and marked throughout the new book's eight chapters, 27 annexes, 170 figures, and 66 tables. Some notable changes are:
