ČSN EN ISO 636   (055312) Svařovací materiály - Tyče a dráty pro obloukové svařování nelegovaných a jemnozrnných ocelí wolframovou elektrodou v inertním plynu a jejich svarové kovy - Klasifikace

Anotace textu normy ČSN EN ISO 636   (055312)

This document specifies requirements for classification of rods and wires in the as-welded condition and in the post-weld heat-treated condition for tungsten inert gas 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.

This document is 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) Paragraphs and tables which carry the suffix letter ´A´ are applicable only to rods and wires classified to the system based upon the yield strength and the average impact energy of 47 J of allweld metal in accordance with this document.

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

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