AWS D1K Subcommittee Revises D1.6 Welding Code for 2017
- Aug 25, 2017 04:01 PM
A brand new edition of AWS D1.6 Structural Welding Code—Stainless Steel is hot off the press! The substantially revised code includes new requirements that address the materials, technologies, and processes that have emerged since the last edition was published in 2007. The AWS D1K Subcommittee on Stainless Steel, which developed the code, also made the 2017 edition more consistent with other AWS standards, clarified clauses that might have led to misinterpretations, and redesigned the layout to make it easier to locate relevant information.
The following list includes some the major revisions included in the 2017 edition of AWS D1.6 Structural Welding Code—Stainless Steel. Make sure to review a copy of the new code for other changes that may not be covered here.
Clause 4: Design of Welded Connections (previously Clause 2)
It has been updated and reorganized to reflect AWS D1.1/D1.1M, Structural Welding Code—Steel where appropriate and references AISC/SCI Design Guide 27: Structural Stainless Steel.
Clause 5: Prequalification and Clause 7: Fabrication
(previously Clause 3 & 5)
Out-of-place subclauses have been placed in the appropriate clause. For example, fabrication requirements were previously located in the Prequalification clause and prequalification requirements were previously located in the Fabrication clause.
Flare-V and flare-bevel-groove welded prequalified joint details have been included for ease of interpretation and consistency with AWS D1.1/D1.1M, Structural Welding Code—Steel. These clauses have also been restructured to follow the standard D1 code format and provide a more logical flow.
Clause 6: Qualification (previously Clause 4)
In the new edition, an individual can now qualify directly to AWS B2.1/B2.1M, Specification for Welding Procedure and Performance Qualification, without approval from the Engineer, all while retaining D1.6 code qualification requirements if the Contractor decides to utilize these.
Clause 8 Inspection (previously Clause 6)
All visual inspection acceptance criteria and NDE personnel qualification requirements have been brought together for ease of use. Visual inspection acceptance criteria were removed from the text and placed in a new Table 8.1, similar to AWS D1.1/D1.1M, Structural Welding Code—Steel. Several errata items, as well as commentary text taken directly from D1.1, were added. Most of the content from Annex E was moved to this clause. Some content from Annexes H and O was also incorporated into Clause 8.
Clause 9 Stud Welding (Previously Clause 7)
Revised to identify numerous improvements already addressed by AWS D1.1/D1.1M, Structural Welding Code—Steel, and AASHTO/AWS D1.5M/D1.5, Bridge Welding Code. The manufacturers’ stud base qualification testing in Annex D was incorporated into this clause.
Annexes A and B
Revised to parallel AWS D1.1/D1.1M, Structural Welding Code—Steel, and employ fillet weld size terms used in AWS A3.0M/A3.0, Standard Terms and Definitions, and A2.4, Standard Symbols for Welding, Brazing, and Nondestructive Examination.
Most of the information in the old Annex E (2007 edition) was moved to Clause 8 in the 2017 revision. The Annex E in the 2017 edition now lists informative references.
