This document specifies requirements for classification of wire electrodes, wires, rods and all-weld metal deposits in the as-welded condition and in the post-weld heat-treated (PWHT) condition for gas shielded metal arc welding and tungsten inert-gas welding of high-strength steels with a minimum yield strength greater than 500 MPa, or a minimum tensile strength greater than 570 MPa. One wire electrode can be tested and classified with different shielding gases.
This document is a combined specification providing for classification utilizing a system based upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal.
a) Clauses, subclauses and tables which carry the suffix letter A are applicable only to wire electrodes, wires, rods and deposits classified according to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal under this document.
b) Clauses, subclauses and tables which carry the suffix letter B are applicable only to wire electrodes, wires, rods and deposits classified according to the system based upon the tensile strength and the average impact energy of 27 J of all-weld metal under this document.
c) 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 document.
Annex A gives information on the description of composition designations for electrodes in the classification system based upon tensile strength and average impact energy of 27 J B.
