20、O 17633:2010ISO 17633:2010(E) iv ISO 2010 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical commi
21、ttees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the I
22、nternational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft Internationa
23、l Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO 17633 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subc
24、ommittee SC 3, Welding consumables. This second edition cancels and replaces the first edition (ISO 17633:2004), of which it constitutes a technical revision. Requests for official interpretations of any aspect of this International Standard should be directed to the Secretariat of ISO/TC 44/SC 3 vi

BS EN ISO 17633:2010ISO 17633:2010(E) ISO 2010 All rights reserved vIntroduction This International Standard provides a classification system for tubular cored electrodes and rods for welding stainless st
26、eels. It recognizes that there are two somewhat different approaches in the global market to classifying a given tubular stainless steel welding consumable, and allows for either or both to be used, to suit a particular market need. Application of either type of classification designation (or of bot
27、h, where suitable) identifies a product as classified in accordance with this International Standard. The classification according to system A is mainly based on EN 12073:19992. The classification according to system B is mainly based upon standards used around the Pacific Rim. BS EN ISO 17633:2010B

29、requirements for classification of tubular flux and metal cored electrodes and rods, based on the all-weld metal chemical composition, the type of electrode core, shielding gas, welding position and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for gas shield
30、ed and non-gas shielded metal arc welding of stainless and heat-resisting steels. This International Standard is a combined standard providing for classification utilizing a system based upon nominal composition or utilizing a system based upon alloy type. a) Clauses, subclauses, and tables which ca
31、rry the suffix letter “A” are applicable only to products classified using the system based upon nominal composition. b) Clauses, subclauses, and tables which carry the suffix letter “B” are applicable only to products classified using the system based upon alloy type. c) Clauses, subclauses, and ta
32、bles which do not have either the suffix letter “A” or the suffix letter “B” are applicable to all tubular cored electrodes classified in accordance with this International Standard. It is recognized that the operating characteristics of tubular cored electrodes can be modified by the use of pulsed
33、current. However, this International Standard does not use pulsed current for determining the electrode classification. 2 Normative references The following referenced documents are indispensable for the application of this document.

37、2-3, Welding consumables Test methods Part 3: Classification testing of positional capacity and root penetration of welding consumables in a fillet weld ISO 80000-1:2009, Quantities and units Part 1: General 3 Classification Classification designations are based upon two approaches to indicating the
38、 chemical composition of the all-weld metal deposit obtained with a given electrode or rod. The “nominal composition” approach uses designation components indicating directly the nominal levels of certain alloying elements, given in a particular order, and some symbols for low but significant levels
39、 of other elements, whose levels are not conveniently expressed as integers. The “alloy type” approach uses tradition-based three- or four-digit designations for alloy families, and an occasional additional character or characters for compositional modifications of each original alloy within the fam
40、ily. This clause includes the symbols for the type of product, the chemical composition of all-weld metal, the type of electrode core, the shielding gas and the welding position, in accordance with the symbols defined in Clause 4. In most cases, a given commercial product can be classified in both s
41、ystems. Then either or both classification designations can be used for the product. 3A Classification according to nominal composition The classification is divided into five parts: a) the first part gives a symbol indicating the product to be identified (see 4.1A); b) the second part gives a symbo
42、l indicating the chemical composition of the all-weld metal (see Table 1A); c) the third part gives a symbol indicating the type of electrode core (see Table 3A); d) the fourth part gives a symbol indicating the shielding gas (see 4.4); e) the fifth part gives a symbol indicating the welding positio
43、n (see Table 4A). 3B Classification according to alloy type The classification is divided into five parts: a) the first part gives a symbol indicating the tubular cored electrode and rod (see 4.1B); b) the second part gives a symbol indicating the chemical composition of the all-weld metal (see Tabl
44、es 1B-1 to -4); c) the third part gives a symbol indicating the type of tubular cored electrode or rod (see Table 3B); d) the fourth part gives a symbol indicating the shielding gas (see 4.4); e) the fifth part gives a symbol indicating the welding position (see Table 4B). The full identification (s
45、ee Clause 11) shall be used on packages and in the manufacturers literature and data sheets. 4 Symbols and requirements A given tubular cored electrode may be classified with more than one shielding gas. In such cases, each shielding gas results in a separate classification. BS EN ISO 17633:2010ISO
46、17633:2010(E) ISO 2010 All rights reserved 34.1 Symbol for the product 4.1A Classification according to nominal composition The symbol for the tubular cored electrode used in the metal arc welding process shall be the letter “T”. 4.1B Classification according to alloy type The symbol for the tubular
47、 cored electrode or rod used in the metal arc welding process shall be the letters “TS”. The initial letter, “T”, indicates tubular cored electrode or rod as distinguished from covered electrodes and from solid electrodes and rods. The second letter, “S”, indicates that the alloy system is stainless
48、 or heat-resisting steel. 4.2 Symbol for the chemical composition of all-weld metal 4.2A Classification according to nominal composition The symbols in Table 1A identify the chemical composition of all-weld metal determined in accordance with Clause 6. The all-weld metal obtained with the tubular co

(See Annex A.) 4.2B Classification according to alloy type The symbols in Table 1B-1 identify the chemical composition of all-weld metal for gas shielded flux cored electrodes determined in accordance with Clause 6. The symbols in Table 1B-2 identify the chemical composition of all-weld metal for non-gas shielded flux cored electrodes determined in accordance with Clause 6. The symbols in Tab
