    The leader in seismic welding solutions is Lincoln Electric. Our leadership comes from our history; for over 100 years Lincoln Electric has been at the forefront of welding technology. It comes from our people; Duane Miller, Lincoln’s Manager of Engineering Services, chaired the D1.8 committee.

  • Page 4: Background

    D1.8 Seismic Supplement Welding Manual Background In January 1994, the Northridge, California earthquake caused unexpected damage to a number of welded steel-framed buildings in the greater Los Angeles area. The Federal Emergency Management Agency (FEMA) funded a variety of investigations that sought to address both the immediate and long-term needs related to solving the performance problems associated with welded steel moment-frame connections.
  • Page 5 FEMA 353 provisions directly into AISC or AWS specifications. AWS D1.8 was approved in 2005 and first printed and distributed in 2006. In 2009 the AWS published the second edition of the AWS D1.8/D1.8M, Structural Welding Code - Seismic Supplement. Subsequent revisions have also been made to this document.

  • Page 7 However, qualifications and various tests done to meet the criteria of FEMA 353 may be used to meet similar or identical requirements in D1.8. Accordingly, such transfer of results is encouraged in D1.8, subject to the Engineer’s approval. For example, the welder qualification test as prescribed in FEMA 353, Appendix B is similar to that specified in D1.8 Annex...

In a manner that has been coordinated with the applicable AISC committees, D1.8 utilizes some new terminology. An understanding of these terms, officially defined in Clause 3: Terms and Definitions of D1.8, is necessary to properly apply the code.

    A User’s Guide to AWS D1.8 Certain portions of D1.8 are more important to some parties than others, depending on their specific role in the construction process. The following is a general summary of sections of particular interest to the various participants in a construction project.

    Techniques Welder Qualification Clause 5 and Annex D of D1.8 are devoted to welder qualification. In addition to meeting the welder qualification requirements of D1.1, welders performing work under D1.8 are required to take the Supplemental Welder Qualification for Restricted Access Welding Test, as prescribed in Annex D, when the production weld involves all of the following: www.lincolnelectric.com...
  • Page 13 The type of test to be taken is dependent on the type of backing (if any) that will be used in production, and as shown on the WPS. See D1.8, clause 5.1.3 and Annex D clause D3.2, D3.3.
  • Page 14 D1.8 as well. In addition to meeting the requirements of D1.1, D1.8 mandates additional WPS requirements. Under D1.8, WPSs must list the filler metal manufacturer as well as the filler metal trade name (such as Lincoln Electric’s Innershield -233) as opposed to showing only the AWS classification (in this case, E71T-8). D1.8 ®...
  • Page 15 D1.8 Seismic Supplement Welding Manual From a practical perspective, it is expected that most contractors doing D1.8 work will use the same filler metals for both Demand Critical welds and other welds that are part of the seismic force resisting system.
  • Page 16 D1.8 requires that the filler metals to be used in production first be evaluated in tests run at high and low levels of heat input, that is, under slow and fast cooling rates. Production welding WPSs are then permitted to use a wide range of variables, providing the calculated heat input levels are within the range of tested values.
  • Page 17 Lincoln Electric products is shown on the documents contained in Appendix A of this manual. Techniques All tack welds made under D1.8 are required to be made with the preheat as listed in the WPS. Tack welding on members in the protected zone is restricted, generally being prohibited except when made in certain locations, such as within the joint.

    D1.8 Seismic Supplement Welding Manual Inspectors. The Inspector’s role with respect to D1.8 is no different than the role as defined by AWS D1.1, namely to ensure that materials and workmanship meet the requirements of the code and contract documents. This is done by performing inspection as necessary prior to assembly, during assembly, during welding, and after welding.

    Regarding Structural Details Ensure that weld access holes are properly prepared. See D1.8, clause 6.9. Ensure that weld tabs and backing have been removed, when required. See D1.8, clause 6.7, 6.10. Regarding the Protected Zone Ensure that no unauthorized welds or attachments have been added. See D1.8, clause 6.15.

    D1.8 Seismic Supplement Welding Manual Lincoln Electric Products The Lincoln Electric Company offers a broad range of filler metals capable of meeting the requirements of AWS D1.8 Seismic Welding Supplement. Whether your choice of welding process is SMAW, FCAW-S, FCAW-G, GMAW, GMAW-C or SAW, Lincoln manufactures and offers consumables that will satisfy D1.8 requirements for nearly every application.
  • Page 21 The requirements for Demand Critical welds are the most rigorous. Filler metals that meet D1.8 requirements for Demand Critical welds will automatically meet all the requirements for welds that are on the SFRS but not Demand Critical. For consistency and simplicity, Lincoln Electric suggests that filler metals that meet the requirements for Demand Critical be used on all welds made on the SFRS.
