26、6:2015ISO 636:2015(E)IntroductionThis International Standard provides a classification for the designation of rods and wires in terms of their chemical composition and, where required, in terms of the yield strength, tensile strength, and elongation of the all-weld metal. The ratio of yield to tensi
27、le strength of weld metal is generally higher than that of parent metal. 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 material. Where the application requires matching tensile strengths,
28、selection of consumables is made by reference to column 3 of Table 1A or Table 1B.Of note is that the mechanical properties of all-weld metal test specimens used to classify the rods and wires vary from those obtained in production joints because of differences in welding procedure such as diameter,
29、 width of weave, welding position, and material composition.The classification according to system A is mainly based on EN 1668:1997. The classification according to system B is mainly based upon standards used around the Pacific Rim. ISO 2015 All rights reserved vBS EN ISO 636:2015BS EN ISO 636:201

31、sten inert gas welding of non-alloy and fine-grain steels with a minimum yield strength of up to 500 MPa or a minimum tensile strength of up to 570 MPa.This International Standard is a combined specification providing classification utilizing a system based upon the yield strength and the average im

33、and the average impact energy of 47 J of all-weld metal in accordance with this International Standard.b) Paragraphs and tables which carry the suffix letter “B” are applicable only to rods and wires classified to the system based upon the tensile strength and the average impact energy of 27 J of al
34、l-weld metal in accordance with this International Standard.c) Paragraphs and tables which have neither the suffix letter “A” nor the suffix letter “B” are applicable to all rods and wires classified in accordance with this International Standard.2 Normative referencesThe following documents, in who

42、 indicating the impact properties of all-weld metal (see Table 2).4) The fourth part gives a symbol indicating the chemical composition of the rods or wires used (see Table 3A).The classification is divided into four parts.1) The first part gives a symbol indicating the product/process to be identif

44、 tensile strength (see Table 2). The letter “U” after this designator indicates that the deposit meets an average optional requirement of 47 J at the designated Charpy test temperature.4) The fourth part gives a symbol indicating the chemical composition of the rods or wires used (see Table 3B).4 Sy
