46、s reserved ISO 636:2017(E)IntroductionThis document 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 tensile streng
47、th 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, selection
48、 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, width of
49、 weave, welding position, and material composition.The classification according to system A is mainly based on EN 1668:19971. The classification according to system B is mainly based upon standards used around the Pacific Rim.
