ASTM A1069/A1069M-11

Standard Specification for Laser-Fused Stainless Steel Bars, Plates, and Shapes

ABSTRACT
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.
SCOPE
1.1 This specification covers laser-fused stainless steel bars, plates, and shapes of structural quality for use in bolted or welded structural applications.
1.2 Shapes covered in this specification include those classified in Article 3.1.2 of Specification A6/A6M and those that are made from two or more shapes or plates.
1.3 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.
1.4 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.
