دانلود کتاب Specification for Carbon Steel Electrodes for Flux Cored Arc Welding

This Specification prescribes the requirements for classification of carbon steel electrodes for flux cored arc welding and will benefit welding professionals. The requirements include chemical composition and mechanical properties of the weld metal and certain usability characteristics. The Specification also includes optional, supplemental designators for improved toughness and diffusible hydrogen and to indicate conformance to special mechanical property requirements when the weld metal is deposited using both low heat input, fast cooling rate and high heat input, slow cooling rate procedures. Additional requirements are included for standard sizes, marking, manufacturing and packaging. A guide is appended to the Specification as a source of information concerning the classification system employed and the intended use of carbon steel flux cored electrodes. This Specification makes use of both U.S. Customary Units and the International System of Units (SI). Since these are not equivalent, each system must be used independently of the other.
