Welding consumables - Wire electrodes, wires, rods and deposits for gas shielded arc welding of high strength steels - Classification
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.
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 – System B.
