适用范围：This International Standard specifies requirements for classification of tubular cored electrodes with or withouta gas shield for metal arc welding of non-alloy and fine grain steels in the as-welded condition or in the postweldheat-treated condition with a minimum yield strength of up to 500 MPa or a minimum tensile strength ofup to 570 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if any.This International Standard is a combined specification providing classification utilizing a system based uponthe yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based uponthe tensile strength and the average impact energy of 27 J of all-weld metal.1) Paragraphs and tables which carry the suffix letter “A” are applicable only to tubular cored electrodesclassified to the system based upon the yield strength and the average impact energy of 47 J of allweldmetal in accordance with this International Standard.2) Paragraphs and tables which carry the suffix letter “B” are applicable only to tubular cored electrodesclassified to the system based upon the tensile strength and the average impact energy of 27 J of allweldmetal in accordance with this International Standard.3) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicableto all tubular cored electrodes classified in accordance with this International Standard.It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use ofpulsed current, but for the purposes of this International Standard, pulsed current is not permitted fordetermining the electrode classification.
