For many years, the D1 Committee has met the needs of structural welding users by publishing codes, starting with the Code for Fusion Welding and Gas Cutting in Building Construction in 1929 by the American Welding Society (AWS). Since then, the committee has addressed the needs of the structural welding community by updating revisions and adding specific codes that are tailored to specific industries as follows: 1. D1.1, Structural Welding Code — Steel (next issue 2015, 4th quarter) 2. D1.2, Structural Welding Code — Aluminum 3. D1.3, Structural Welding Code — Sheet Steel 4. D1.4, Structural Welding Code — Reinforcing Steel 5. D1.5, Bridge Welding Code (next issue 2015, 4th quarter) 6. D1.6, Structural Welding Code — Stainless Steel (next issue 2016) 7. D1.7, Guide for Strengthening and Repairing Existing Structures 8. D1.8, Structural Welding Code — Seismic Supplement 9. D1.9, Structural Welding Code — Titanium. Many of these codes are now recognized in the international community for use in structural execution or by other standards committees throughout the world as a source for technical references used to assist in their respective committees. As such, revisions revision process and these two codes will be to these standards are vital to the industry issued later this for providing leading technology and year.” WJ user friendliness to a constantly changing marketplace for structural execution. The D1 Committees for D1.1 and D1.5 have successfully completed the revision process and these two codes will be issued later this year. For the revisions to AWS D1.1, Structural Welding Code — Steel, the most notable areas are as follows: • All tubular provisions are now moved to a new clause, “Tubular Structures.” • Addition of AWS A5.36, Specification for Carbon and Low-Alloy Steel Flux Cored Electrodes for Flux Cored Arc Welding and Metal Cored Electrodes for Gas Metal Arc Welding, fixed and open classification requirements. • Fatigue curve classes and figures revised to align with the American Institute of Steel Construction (AISC). • Clarifications of Charpy V-notch (CVN) test requirements for subsized specimens. • Sample welding forms have been revised. • New figures to clarify effective throats for various joint types and combinations. To summarize, the D1 Committees are looking beyond — into the future — for what challenges may be ahead. It is clear all of us are increasing our awareness of sustainability and the efficient use of resources. To this end, processes that improve efficiencies recognized by codes like D1.1 must be incorporated in a timely fashion. Some of these could be phased array ultrasonic testing, wave formed controlled power sources, improved utilization of raw material product forms utilizing international standards, and/or additive manufacturing. What remains is for those with this vision to join us and help shape the future and beyond.
