This specification covers laser-fused stainless steel bars, plates, and shapes of structural quality for use in bolted or welded structural applications. The butt-welded test pieces are welded using laser fusion and then machined into tensile test bars and root-bend test specimens. The term laser fusion is used in this specification to refer to a joining process that is able to produce a coalescence of material using the heat obtained from the application of a concentrated coherent light beam impinging on the surface of a weld joint.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers laser and laser hybrid welded austenitic, ferritic, and duplex (ferritic-austenitic) stainless steel bars, plates, and shapes of structural quality for use in bolted or welded structural applications.
Note 1: The term laser fusion is also used to describe laser welding.
1.1.1 Supplementary requirements (S1, S2, S3) of an optional nature are provided. They shall apply only when specified by the purchaser.
1.2 Shapes covered in this specification include those classified in Article 3.1.2 of Specification , Specification square and rectangular hollow sections, and additional shapes, including customized, that are made from two or more shapes or plates.
1.3 This specification establishes the minimum requirements for manufacturing of laser and laser hybrid welded stainless steel shapes.
1.4 This specification refers to Specifications , , , or for chemical requirements, but the mechanical test requirements are determined by the mechanical properties section of this standard.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
