ASTM International Standard Specification for Laser and Laser Hybrid Welded Stainless Steel Bars, Plates, and Shapes ASTM A1069/A1069M-19

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.
