20、ice The text of ISO 14344:2010 has been approved by CEN as an EN ISO 14344:2010 without any modification. EN ISO 14344:2010 (E) DIN EN ISO 14344:2010-06 31 Scope This International Standard specifies tools for communication between a purchaser and a supplier of welding consumables within quality sys

21、tems, such as those based upon ISO 90011. In production, the components of welding consumables are divided into discrete, predetermined quantities so that satisfactory tests with a sample from that quantity will establish that the entire quantity meets specification requirements. These quantities, k

22、nown by such terms as heats, lots, blends, batches and mixes, vary in size according to the manufacturer. For identification purposes, each manufacturer assigns a unique designation to each quantity. This designation usually consists of a series of numbers or letters, or combinations thereof, which

23、will enable the manufacturer to determine the date and time (or shift) of manufacture, the type and source of the raw materials used, and the details of the procedures used in producing the welding consumable. This designation stays with the welding consumable and can be used to identify the materia

24、l later, in those cases in which identification is necessary. This International Standard, together with an applicable International Standard or other standard for welding consumables, provides a method for preparing those specific details needed for welding consumable procurement which consist of:

25、a) the welding consumable classification (selected from the applicable International Standard or other standard for welding consumables); b) the lot classification (selected from Clause 4); c) the testing schedule (selected from Clause 5). Selection of the specific welding consumable classification,

26、 lot classification, and testing schedule depends upon the requirements of the application for which the welding consumable is being procured. This International Standard does not apply to non-consumable electrodes or shielding gases. 2 Terms and definitions For the purposes of this International St

27、andard, the following terms and definitions apply. 2.1 dry batch quantity of dry ingredients mixed at one time in one mixing vessel NOTE Liquid binder, when added to a dry batch, produces a wet mix. A dry batch can be divided into smaller quantities, in which case addition of the liquid binder produ

29、ents are as uniformly dispersed as they would have been had the entire quantity been mixed together at one time in one large mixer NOTE A dry blend, as in the case of a dry batch, can be used singly or divided into smaller quantities which, when the liquid binder is added, produce one or more wet mi

30、xes. 2.3 wet mix combination of liquid binder and a dry batch or dry blend, or a portion thereof, mixed at one time in one mixing vessel 2.4 Heat 2.4.1 heat open hearth, electric arc, basic oxygen, argon-oxygen processes for consumable inserts, solid wires, rods and strip, core wire for covered elec

32、rods and strip, core wire for covered electrodes, and the sheath (strip or tubing of tubular cored electrode wire and rod), an uninterrupted series of melts from one controlled batch of metals and alloying ingredients in one melting furnace under the same melting conditions, each melt conforming to

33、the chemical composition range approved by the purchaser of the material (i.e. the producer of the welding consumable) where significant chemical reactions do not occur in producing the metal 2.4.3 heat consumable electrode remelt for consumable inserts, solid wires, rods and strip, core wire for co

35、on range approved by the purchaser of the material (i.e. the producer of the welding consumable) in processes involving continuous melting and casting 3 Identification 3.1 General Identification of consumable inserts, solid wires, rods and strip, core wire for covered electrodes, and the sheath (str

36、ip or tubing) for tubular cored electrodes and rods shall be applied as listed in 3.2 to 3.3.1. Identification of covering mix of covered electrodes, core ingredients of tubular cored electrode wire or rod, and fluxes for submerged arc welding shall be applied as listed in 3.3.2 to 3.6. 3.2 Heat num

37、ber Consumable inserts, solid wires, rods and strip, core wire for covered electrodes, and the sheath (strip or tubing) for tubular cored electrodes and rods, identified by heat number, shall consist of material from a single heat of metal.

38、led chemical composition 3.3.1 Consumable inserts, solid wires, rods and strip, core wire for covered electrodes, and the sheath (strip or tubing) for tubular cored electrodes and rods identified by controlled chemical composition, rather than by heat number, shall consist of mill coils of one or mo

39、re heats from which samples have been taken for chemical analysis. The results of the analysis of each sample shall be within the manufacturers composition limits for that material. Coils from mills that do not permit spliced-coil practice need be sampled on only one end. Coils from mills that permi

40、t spliced-coil practice shall be sampled on both ends and shall have no more than a single splice per coil. 3.3.2 Covering or fluxes identified by controlled chemical composition rather than by wet mix shall consist of one or more wet mixes and shall be subjected to sufficient tests to ensure that a

41、ll wet mixes within the lot are equivalent. These tests shall include chemical analysis, the results of which shall fall within the manufacturers acceptance limits. The identification of the test procedure and the results of the tests shall be recorded. Alternatively, when the chemical composition o

42、f wet mixes is controlled by raw material analysis and computerized weighing, it can be assumed that all wet mixes within the lot are equivalent. 3.3.3 Core ingredients or fluxes identified by controlled composition rather than by dry blend shall consist of one or more dry blends and be subjected to

43、 sufficient tests to ensure that all dry blends within the lot are equivalent. These tests shall include chemical analysis, the results of which shall fall within the manufacturers acceptance limits. The identification of the test procedure and the results of the tests shall be recorded. Alternative

44、ly, when the chemical composition of dry blends is controlled by raw material analysis and computerized weighing, it can be assumed that all dry blends within the lot are equivalent. 3.4 Covering mix In the production of covered electrodes, the covering mix shall be identified either by wet mix (see

45、 2.3) or by controlled chemical composition (see 3.3.2). A covering identified by wet mix shall consist of a single wet mix for each lot of electrodes. 3.5 Core ingredients In the production of tubular cored electrode wire or rod (flux cored or metal cored welding consumables), the core ingredients

46、shall be identified either by dry blend (see 2.2) or by controlled chemical composition (see 3.3.3). Core ingredients identified by dry blend shall consist of a single dry batch or blend. 3.6 Fluxes for submerged arc welding In the production of fused and mixed fluxes for electro-slag and submerged

47、arc welding, the flux ingredients shall be identified either by dry blend (see 2.2) or by controlled chemical composition (see 3.3.3). In the production of agglomerated fluxes for electro-slag and submerged arc welding, the flux ingredients shall be identified either by wet mix (see 2.3) or by contr

48、olled chemical composition (see 3.3.2). Fluxes identified by dry blend shall consist of a single dry batch or blend. Fluxes identified by wet mix shall consist of a single wet mix. 4 Lot classification 4.1 Bare solid electrode wires and strips, rods and consumable inserts 4.1.1 Class S1 A class S1 l

49、ot of bare solid electrodes and rods or consumable inserts is the manufacturers standard lot, as defined in the manufacturers quality assurance programme. EN ISO 14344:2010 (E) DIN EN ISO 14344:2010-06 64.1.2 Class S2 A class S2 lot of bare solid electrodes and rods or consumable inserts is the quantity, not exceeding 45 000 kg, of one classification, size, form, and temper produced in 24 h of consecutively scheduled production (i.e. consecutive normal work shifts). Class S2 solid electrodes and rods or consumable inserts shall be produced from
