ISO 18275:2018 pdf free.Welding consumables一Covered electrodes for manual metal arc welding of high-strength steels
This document specifies requirements for classification of covered electrodes and deposited metal in the as-welded condition and in the post-weld heat-treated condition for manual metal arc welding of high-strength steels with a minimum yield strength greater than 500 MPa or a minimum tensile strength greater than 570 MPa.
This document is a combined specification providing a classification utilizing a system based on the yield strength and an average impact energy of 47 J of the all-weld metal, or utilizing a system based on the tensile strength and an average impact energy of 27 J of the all-weld metal.
a) Subclauses and tables which carry the suffix letter “A” are applicable only to covered electrodes classified under the system based on the yield strength and an average impact energy of 47 J of the all-weld metal given in this document.
b) Subclauses and tables which carry the suffix letter “B” are applicable only to covered electrodes classified under the system based on the tensile strength and an average impact energy of 27 J of the all-weld metal given in this document.
c) Subclauses and tables which do not have either the suffix letter “A” or the suffix letter“B” are applicable to all covered electrodes classified under this document.
