21、o reproduction or networking permitted without license from IHS -,-,- iv Introduction This 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 elongatio
22、n of the all-weld metal. The ratio of yield to tensile strength of weld metal is generally higher than that of parent metal. Users should 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 p
23、arent material. Where the application requires matching tensile strengths, selection of consumable should be made by reference to column 3 of Table 1A or Table 1B. It should be noted that the mechanical properties of all-weld metal test specimens used to classify the rods and wires vary from those o
24、btained in production joints because of differences in welding procedure such as diameter, width of weave, welding position and material composition. The classification according to system A is mainly based on EN 1668:1997, Welding consumables Rods, wires and deposits for tungsten inert gas welding
