AWS A5.17-A5.17M:1997 pdf download.Specification for Carbon Steel Electrodes and Fluxes for Submerged Arc Welding
1. Scope
This specification prescribes requirements for the classification of carbon steel electrodes (both solid and composite) and fluxes for submerged are welding.
This document is the first of the A5.17 specifications which is a combined specification providing for classification utiliz-ing a system based upon U.S Customary Units, or utilizing a system based upon the Intemational System of Units (SD). The measurements are not exact equivalents; therefore, each sys-tem must be used independently of the other, without combin-ing 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 applica-tion of the specified tolerances, provides for interchange-ability of products in both U.S. Customary and SI Units.
(1) Paragraphs, tables and figures which carry the suf-fix letter“U" are applicable only to those products classi-fied to the system based upon U.S. Customary Units under the A5. 17 specification.
(2) Paragraphs, tables and figures which carry the suf-fix letter“M" are applicable only to those products clas-sified to the system based upon the 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. Custom-ary Units System or the Intermnational System of Units (SI).
7.1.1 Solid Electrodes. Chemical analysis of the elec-trode is the only test required for classification of a solid electrode under this specification. The chemical analysis of the rod stock from which the electrode is made may also be used, provided the electrode manufacturing pro-cess does not alter the chemical composition.
7.1.2 Composite Electrodes. Chemical analysis of weld metal produced with the composite electrode and a particular flux is the only test required for classification of a composite electrode under this specification.
8. Retest
If the results of any test fail to meet the requirement,that test shall be repeated twice. The results of both re-tests shall meet the requirement. Material, specimens, or samples for retest may be taken from the original test as-sembly or sample or from one or two new test assemblies or samples. For chemical analysis, retest need be only for those specific elements that failed to meet the test re-quirement. If the results of one or both retests fail to meet the requirement, the material under test shall be consid-ered as not meeting the requirements of this specification for that classification.AWS A5.17-A5.17M pdf download.
