AWS A5.5M: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 shielded 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 concems 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 A10. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, 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 Intermational 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.
6. Rounding Procedure
For the purpose of determining compliance with the requirements of this standard, the actual test values obtained shall be subjected to the rounding rules of ASTM E29 or Rule A in Clause B.3 of ISo 80000- 1:2009 (the results are the same).If the measured values are obtained by equipment calibrated in units other than those of the specified limit, the measured values shall be coverted to the units of the specified limit before rounding. If an average value is to be compared to the specified limit, rounding shall be done only qfter calculating the average. An obsenved or calculated value shall be rounded to the nearest 1000 psi ( ksi) for tensile and yield strength for A5.5;AWS A5.5M pdf download.
