ČSN EN ISO 14341   (055311) Svařovací materiály - Drátové elektrody pro obloukové svařování nelegovaných a jemnozrnných ocelí v ochranném plynu a jejich svarové kovy - Klasifikace

Anotace textu normy ČSN EN ISO 14341   (055311)

This document specifies requirements for classification of wire electrodes and weld deposits in the as-welded condition and in the post-weld heat-treated condition for gas shielded metal arc welding of non alloy and fine grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa. One wire electrode can be tested and classified with different shielding gases.

This document constitutes a combined specification providing 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 and tables which carry the suffix letter ´A´ are applicable only to wire electrodes classified to the system based on the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this document.

b) Clauses and tables which carry the suffix letter ´B´ are applicable only to wire electrodes classified to the system based on the tensile strength and the average impact energy of 27 J of all-weld metal in accordance with this document.

c) Clauses and tables which have neither the suffix letter ´A´ nor the suffix letter ´B´ are applicable to all wire electrodes classified in accordance with this document.
