发布日期：2007-11

标准范围

This International Standard specifies requirements for classification of wire electrodes, wires and rods forgas-shielded metal arc welding and tungsten inert-gas welding of creep-resisting steels, and for their depositsin the as-welded or post-weld heat-treated condition. One wire electrode can be tested and classified withdifferent shielding gases.This International Standard is a combined specification providing for classification utilizing a system basedupon the chemical composition of wire electrodes, wires and rods with requirements for yield strength andaverage impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength of theall-weld metal deposits and the chemical composition of wire electrodes, wires and rods.1) Clauses, subclauses and tables which carry the suffix letter “A” are applicable only to wire electrodes,wires, rods and deposits classified in accordance with the system based upon the chemicalcomposition with requirements for yield strength and the average impact energy of 47 J of all-weldmetal deposits under this International Standard.2) Clauses, subclauses and tables which carry the suffix letter “B” are applicable only to wire electrodes,wires, rods and deposits classified in accordance with the system based upon the tensile strength ofall-weld metal deposits and the chemical composition of wire electrodes, wires and rods under thisInternational Standard.3) Clauses, subclauses and tables which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all wire electrodes, wires, rods and deposits classified under this International Standard.
