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
25、of non alloy and fine grain steels Classification. The classification according to system B is mainly based upon standards used around the Pacific Rim. Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 3, via your

27、permitted without license from IHS -,-,- 1 Welding consumables Rods, wires and deposits for tungsten inert gas welding of non-alloy and fine-grain steels Classification 1 Scope This International Standard specifies requirements for classification of rods and wires in the as-welded condition and in t
28、he post-weld heat-treated condition for tungsten 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 bas
29、ed upon the yield strength and the average impact energy of 47 J of all-weld metal, or utilizing a system based upon the tensile strength and the average impact energy of 27 J of all-weld metal. 1) Paragraphs and tables which carry the suffix letter “A” are applicable only to rods and wires classifi

31、ngth and the average impact energy of 27 J 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 all rods and wires classified in accordance with this International Standard. 2 N

36、rom IHS -,-,- 2 3 Classification Classification designations are based upon two approaches to indicate the tensile properties and the impact properties of the all-weld metal obtained with rods or wires. The two designation approaches include additional designators for some other classification requi
37、rements, but not all, as will be clear from the following sections. In most cases, a given commercial product can be classified to the classification requirements in both systems. Then either or both classification designations can be used for the product. Rods or wires shall be classified according
38、 to their chemical composition in accordance with Table 3A or Table 3B. 3A Classification by yield strength and 47 J impact energy The classification is divided into four parts: 1) the first part gives a symbol indicating the product/process to be identified; 2) the second part gives a symbol indica
39、ting the strength and elongation of the all-weld metal (see Table 1A); 3) the third part gives a symbol 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). 3B Classification
40、by tensile strength and 27 J impact energy The classification is divided into four parts: 1) the first part gives a symbol indicating the product/process to be identified; 2) the second part gives a symbol indicating the strength and elongation of the all-weld metal in either the as-welded or post-w
41、eld heat-treated condition (see Table 1B); 3) the third part gives a symbol indicating the impact properties of all-weld metal in the same condition as specified for the tensile strength (see Table 2). The letter “U” after this designator indicates that the deposit meets an average optional requirem
42、ent 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 Symbols and requirements 4.1 Symbol for the product/process The symbol of weld deposit by the tungsten inert gas welding process sh
43、all be the letter “W” placed at the beginning of the designation. The symbol of rods or wires for the tungsten inert gas welding shall be the letter “W” placed at the beginning of the rod or wire designation. 4.2 Symbol for strength and elongation of all-weld metal 4.2A Classification by yield stren
44、gth and 47 J impact energy The symbol in Table 1A indicates yield strength, tensile strength and elongation of the all-weld metal in the as-welded condition determined in accordance with Clause 6. 4.2B Classification by tensile strength and 27 J impact energy The symbol in Table 1B indicates yield s
45、trength, tensile strength and elongation of the all-weld metal in the as-welded condition or in the post-weld heat- treated condition determined in accordance with Clause 6.
