AWS A5.17/A5.17M PDF

This specification prescribes requirements for the classification of carbon steel electrodes (both solid and composite) and fluxes for submerged arc welding.

This document is the first of the A5.17 specifications which is a combined specification providing for classification utilizing a system based upon U.S. Customary Units, or utilizing a system based upon the International System of Units (SI). The measurements are not exact equivalents; therefore, each system must be used independently of the other, without combining values in any way. In selecting rational metric units, ANSI/AWS A1.1, Metric Practice Guide for the Welding Industry, is used where suitable. Tables and Figures make use of both U.S. Customary Units and SI Units which, with the application of the specified tolerances, provides for interchangeability of products in both U.S. Customary and SI Units.

(1) Paragraphs, tables and figures which carry the suffix letter "U" are applicable only to those products classified to the system based upon U.S. Customary Units under the A5.17 specification.

(2) Paragraphs, tables and figures which carry the suffix letter "M" are applicable only to those products classified to the system based upon International System of Units (SI), under the A5.17M specification.

(3) Paragraphs, tables and figures which do not have either the suffix letter "U" or the suffix letter "M" are applicable to those products classified under either the U.S. Customary Units System or the International System of Units (SI).

Abstract

This specification provides requirements for the classification of solid and composite carbon steel electrodes and fluxes for submerged arc welding. Electrode classification is based on chemical composition of the electrode for solid electrodes, and chemical composition of the weld metal for composite electrodes. Flux classification is based on the mechanical properties of weld metal produced with the flux and an electrode classified herein. Other requirements include sizes, marking, manufacturing and packaging. The form and usability of the flux are also included.

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.
