Elektroda e saldimi - Elektrodat në formë teli, telat, shufrat dhe depozitat për saldimin me hark me gaz të mbrojtur të çeliqeve rezistente ndaj rrjedhjes - Klasifikimi (ISO 21952:2012)

Welding consumables - Wire electrodes, wires, rods and deposits for gas shielded arc welding of creep-resisting steels - Classification (ISO 21952:2012)

Scope

ISO 21952:2012 specifies requirements for classification of wire electrodes, wires and rods for gas shielded metal arc welding and tungsten inert-gas welding of creep-resisting steels, and for their deposits in the as-welded or post-weld heat-treated condition. One wire electrode can be tested and classified with different shielding gases.
ISO 21952:2012 is a combined specification providing for classification utilizing a system based upon the chemical composition of wire electrodes, wires and rods with requirements for yield strength and average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength of the all-weld metal deposits and the chemical composition of wire electrodes, wires and rods.
