In selecting rational metric units, AWS A1.1, MetricPractice Guide for the Welding Industry, and International Standard ISO 544, Welding consumables Technical deliv-ery conditions for welding filler materials and fluxes Type of product, dimensions, tolerances and markings, are usedwhere suitable.
29、 Tables and figures make use of both U.S. Customary and SI units, which with the application of thespecified tolerances provides for interchangeability of products in both the U.S. Customary and SI units.

30、des for manual metal arc weldingof nickel and nickel alloys Classification.The first specification for nickel and nickel-alloy covered electrodes was issued in 1954 by a joint committee of theAmerican Society for Testing and Materials and the American Welding Society. The first revision in 1964 was
31、also theresult of the cooperative effort. This revision is the eighth prepared entirely by the AWS A5 Committee on Filler Metalsand Allied Materials.Substantive changes, such as addition of new filler metal classifications ENiCrFe-15 and ENiMoCr-1 along with chem-ical composition change in ENiCrMo-1
32、9 are shown in Italic font.The requester of the chemical composition change for ENiCrMo-19 classification stated that this alloy is not patented inUSA, but patented in Germany (patent DE 59801333), France (patent FR 991788), and the UK (GB 991788). All ofthese were generated out of the European pate
33、nt EP991788 and will expire on May 27, 2018.Requirements for diameter and length, core wire and covering, exposed core, electrode identification, packaging, andmarking of packages now refer to AWS A5.02/A5.02M.NOTE: The users attention is called to the possibility that compliance with this standard
34、may require use of aninvention covered by patent rights. By publication of this standard, no position is taken with respect to the validityof any such claim or of any patent rights in connection therewith. If the patent holder has filed a statement ofwillingness to grant a license under these rights

46、Metal Arc Welding1. Scope1.1 This specification prescribes requirements for the classification of nickel and nickel-alloy covered electrodes forshielded metal arc welding. It includes those compositions in which the nickel content generally exceeds that of anyother element.11.2 This specification ma
47、kes use of both U.S. Customary Units and the International System of Units (SI). The measure-ments are not exact equivalents; therefore, each system must be used independently of the other without combining inany way when referring to material properties. The specification with the designation A5.11
48、 uses U.S. Customary Units.The specification A5.11M uses SI Units. The latter are shown within brackets ( ) or in appropriate columns in tablesand figures. Standard dimensions based on either system may be used for sizing of filler metal or packaging or bothunder A5.11 or A5.11M specifications.1.3 S
