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, wires and deposits 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) Components which carry the suffix ´system A´ are applicable only to rods, wires and deposits classified to the system based upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this document.

b) Components which carry the suffix ´system B´ are applicable only to rods, wires and deposits 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) Components which have neither the suffix ´system A´ nor the suffix ´system B´ are applicable to all rods, wires and deposits classified in accordance with this document.
