30、ed electrodes in terms of tensile properties, impact properties, chemical composition of the all-weld metal, type of electrode core, shielding gas, and welding position. The ratio of yield to tensile strength of weld metal is generally higher than that of the parent metal. Matching weld metal yield

31、strength to parent metal yield strength will not necessarily ensure that the weld metal tensile strength matches that of the parent metal. Where the application requires matching tensile strengths, selection of consumables is made by reference to column 3 of Table 1A or Table 1B.Of note is that the

32、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 the differences in welding procedure such as electrode size, width of weave, welding position, and parent metal composition.The classific

33、ation in accordance with system A is mainly based on EN 758:1997. The classification in accordance with system B is mainly based upon standards used around the Pacific Rim.

35、 condition or in the post-weld heat-treated condition with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.

46、s and the impact properties of the all-weld metal obtained with a given electrode. The two designation approaches include additional designators for some other classification requirements, but not all as will be clear from the following. In most cases, a given commercial product can be classified in

47、 both systems. Then, either or both classification designations can be used for the product (see Annex A).The classification includes all-weld metal properties obtained with a tubular cored electrode and appropriate shielding gas combination as given below. With the exception of the symbol for weldi

48、ng position which is based on ISO 15792-3, the classification of gas shielded tubular cored electrodes is based on the 1,2 mm electrode size or if this size is not manufactured, the next larger diameter manufactured.

49、 diameter or the largest diameter manufactured if less than 2,4 mm.3.1A Classification by yield strength and 47 J impact energy3.1B Classification by tensile strength and 27 J impact energyThe classification is divided into eight parts.
