33、of shielding gas, and welding position or in terms of the tensile properties, chemical composition of the all-weld metal, usability characteristics of the electrodes, shielding gas, and welding position. The ratio of proof to tensile strength of weld metal is generally higher than that of parent met
34、al. Matching weld metal proof strength to parent metal proof strength will not necessarily ensure that the weld metal tensile strength matches that of the parent metal. Where the application requires matching tensile strength, therefore, selection of consumables is made by reference to column 4 of T
35、able 2.Of note is that the mechanical properties of all-weld metal test specimens used to classify the tubular cored electrodes will vary from those obtained in production joints because of differences in welding procedure such as electrode size, width of weave, welding position, and parent metal co
36、mposition.The classification according to system A is mainly based on EN 12071:1999. The classification according to system B is mainly based upon standards used around the Pacific Rim.4EN ISO 17634:2015 (E) DIN EN ISO 17634:2015-12 1 ScopeThis International Standard specifies requirements for class
37、ification of tubular cored electrodes used in the post-weld heat-treated condition for gas shielded metal arc welding of creep-resisting and low alloy elevated temperature steels. One tubular cored electrode can be tested and classified with different shielding gases.This International Standard is a
38、 combined specification providing for classification utilizing a system based upon the chemical composition of all-weld metal or utilizing a system based upon the tensile strength and the chemical composition of all-weld metal.1) Paragraphs and tables which carry the suffix letter “A” are applicable
39、 only to tubular cored electrodes classified to the system based upon chemical composition with requirements for the yield strength and the average impact energy of 47 J of all-weld metal in accordance with this International Standard.2) Paragraphs and tables which carry the suffix letter “B” are ap
40、plicable only to tubular cored electrodes classified to the system based upon the tensile strength and chemical composition of all-weld metal in accordance with this International Standard.3) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicable to a
41、ll 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 of pulsed current, but for the purposes of this International Standard, pulsed current is not used for dete
42、rmining the electrode classification.2 Normative referencesThe following referenced documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

46、 (E) DIN EN ISO 17634:2015-12 3 ClassificationClassification designations are based upon two approaches to indicate the chemical composition, the tensile properties, and the impact properties of the all-weld metal obtained with a given electrode. The two designation approaches include additional des
47、ignators for some other classification requirements, but not all as will be clear from the following sections. In most cases, a given commercial product can be classified in both systems. Then, either or both classification designations can be used for the product.The classification includes all-wel
48、d metal properties obtained with a tubular cored electrode and appropriate shielding gas combination as given below. With the exception of the symbol for welding position which is based on ISO 15792-3, the classification is based on the tubular cored electrode size 1,2 mm or if this is not manufactu
49、red, the next larger diameter manufactured.3.1A Classification by chemical composition 3.1B Classification by tensile strength and chemical compositionThe classification is divided into six parts: The classification is divided into seven parts:1) The first part (T) indicates a tubular cored electrode.1) The first part (T) indicates a tubular cored electrode.2) The second part gives a symbol indicating the chemical composition of all-weld metal (see Table 1).2) The second part gives a symbol
