CSA Preface
This is the second edition of CAN/CSA-ISO 14341, Welding consumables - Wire electrodes and weld deposits for gas shielded metal arc welding of non alloy and fine grain steels - Classification, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 14341 (second edition, 2010-02-15). This Standard supersedes the previous edition published in 2006 as CAN/CSA-ISO 14341 (adopted ISO 14341:2002).
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope
This International Standard 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 International Standard 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 upon the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard.
b) Clauses and tables which carry the suffix letter B are applicable only to wire electrodes 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 International Standard.
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 International Standard.
