41、 at www .iso .org.DIN EN ISO 18276:2017-07 EN ISO 18276:2017 (E) 4 IntroductionThis document proposes a classification system for tubular cored electrodes in terms of the tensile properties, impact properties, chemical composition of the all-weld metal, type of electrode core, shielding gas and weld

42、ing position. The ratio of yield strength to tensile strength of the weld metal is generally higher than that of the parent metal. Note that matching weld metal yield strength to parent metal yield strength will not necessarily ensure that the weld metal tensile strength matches that of the parent m

43、etal. Where the application requires matching tensile strength, therefore, selection of the consumable should be made by reference to column 3 of Table 1A or Table 1B.Note that the mechanical properties of all-weld metal test specimens used to classify tubular cored electrodes will differ from those

44、 obtained with production joints because of differences in welding procedure such as electrode size, width of weave, welding position and parent metal composition.The classification in accordance with system A is mainly based on EN 125351. The classification in accordance with system B is mainly bas

45、ed upon standards used around the Pacific Rim.DIN EN ISO 18276:2017-07 EN ISO 18276:2017 (E) 5 1 ScopeThis document specifies the requirements for classification of tubular cored electrodes with or without a gas shield for metal arc welding of high-strength steels in the as-welded condition or in th

46、e post-weld heat-treated condition with a minimum yield strength higher than 550 MPa or a minimum tensile strength higher than 590 MPa. One tubular cored electrode can be tested and classified with different shielding gases, if used with more than one.This document is a combined specification provid
