AWS A5.10:2017 pdf download.Welding Consumables - Wire Electrodes,Wires and Rods for Welding of Aluminum and Aluminum Alloys - Classification
1. Scope
1.1 AWS A5.10 specifies requirements for classification of solid wires and rods for fusion welding of aluminum and aluminum alloys. The classification of the solid wires and rods is based on their chemical composition.
1.2 Safety and health issues and concems are beyond the scope of this standard and are therefore not fully addressed herein. Some safety and health information can be found in the nonmandatory Annex A Clauses A6 and A13. Safety and health information is available from other sources, including, but not limited to, ANSI Z49.1, Safety 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 measure-ments are not exact equivalents; therefore, each system must be used independently of the other without combining in any way when referring to weld metal properties. The specification A5.10 uses U.S. Customary Units. The specification with the designation A5. 10M uses SI Units. The latter are shown within brackets [ ] or in appropriate columns in tables and fgures. Standard dimensions based on either system may be used for the sizing of electrodes or packaging or both under specification A5.10 or A5.10M.
2. Normative References
This standard incorporates, by dated or undated reference, provisions from other publications. These normative refer-ences are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, sub-sequent amendments to or revisions of any of these publications apply to this standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
6. Rounding Procedure
For purposes of determining compliance with the requirements of this standard, the actual test values obtained shall be subjected to the rounding rules of ASTM E 29 or ISO 80000-1, Part I (the results are the same). If the measured valucs are obtained by equipment calibrated in units other than those of the specified limit, the measured values shall be con-verted 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 after calculating the average. An observed or calculated value shall be rounded to the nearest unit in the last right-hand place of figures used in expressing the limiting values. The rounded results shall fulfill the requirements for the classification under test.AWS A5.10 pdf download.
