AWS 5.5M:2014 pdf download.Specification for Low-Alloy Steel Electrodes for Shielded Metal Arc Welding
1. Scope
1.1 This specification prescribes requirements for the classification of low-alloy steel electrodes for shiclded metal are welding of carbon and low alloy steels. These electrodes include steel alloys in which no single alloying clement exceeds 10.5%.
1.2 Safety and health issues and concerns are beyond the scope of this standard and, therefore, are not fully addressed herein. Some safety and health information can be found in nonmandatory annex Clauses A5 and AI0. Safety and health information is available from other sources, including, but not limited to, ANSI 249.1, Safery in Welding, Cutting, and Allied Processes, and applicable federal and state regulations.
1.3 This specification makes use of both U.S. Customary Units and the International System of Units (SD). The measurements are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to material properties. The specification designated A5.5 uses U.S. Customary Units; and the specification designated A5.5M uses SI Units. The latter units are shown within brackets [ ] or in appropriate columns in tables and figures. Standard dimensions based on either system may be used for sizing of fller metal or packaging or both under A5.5 or A5.5M specification.
2. Normative References
2.1 The following standards contain provisions that, through reference in this text, constitute provisions of this AWS standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreement based on this AWS standard are encouraged to investigate the possibility of applying the most recent edition of the documents shown below. For undated references, the latest edition of the standard referred to applies.
8. Retest
If the results of any test fail to meet the requirement, that test shall be repeated twice. The results of both retests shall meet the requirement. Specimens for retest may be taken from the original test assembly or from a new test assembly. For chemical analysis, retest need be only for those specific elements that failed to meet the test requirement. If the results of one or both retests fail to meet the requirement, the material under test shall be considered as not mecting the require-ments of this specification for that classification.
In the event that, during preparation or after completion of any test, it is clearly determined that prescribed or proper pro-cedures were not followed in preparing the weld test assembly or in conducting the test, the test shall be considered invalid, without regard to whether the test was actually completed, or whether test results met, or failed to meet, the requirement. That test shall be repeated, following proper prescribed procedures. In this case, the requirement for dou-bling the number of test specimens does not apply.AWS 5.5M pdf download.
