15、erials and fluxes 1 Scope This International Standard specifies tools for communication between a purchaser and a supplier of welding consumables within quality systems, such as those based upon ISO 90011. In production, the components of welding consumables are divided into discrete, predetermined

16、quantities so that satisfactory tests with a sample from that quantity will establish that the entire quantity meets specification requirements. These quantities, known by such terms as heats, lots, blends, batches and mixes, vary in size according to the manufacturer. For identification purposes, e

17、ach manufacturer assigns a unique designation to each quantity. This designation usually consists of a series of numbers or letters, or combinations thereof, which will enable the manufacturer to determine the date and time (or shift) of manufacture, the type and source of the raw materials used, an

18、d 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 material later, in those cases in which identification is necessary. This International Standard, together with an applicable International Sta

19、ndard or other standard for welding consumables, provides a method for preparing those specific details needed for welding consumable procurement which consist of: a) the welding consumable classification (selected from the applicable International Standard or other standard for welding consumables)

20、; b) the lot classification (selected from Clause 4); c) the testing schedule (selected from Clause 5). Selection of the specific welding consumable classification, lot classification, and testing schedule depends upon the requirements of the application for which the welding consumable is being pro

21、cured. This International Standard does not apply to non-consumable electrodes or shielding gases. 2 Terms and definitions For the purposes of this International Standard, the following terms and definitions apply. 2.1 dry batch quantity of dry ingredients mixed at one time in one mixing vessel NOTE

22、 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 produces as many wet mixes as there are smaller quantities.

23、 welding consumables two or more dry batches from which quantities of each are combined proportionately, then mixed in a mixing vessel to produce a larger quantity in which the ingredients are as uniformly dispersed as they would have been had the entire quantity been mixed together at one time in o

24、ne 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 mixes. 2.3 wet mix combination of liquid binder and a dry batch or dry blend, or a portion thereof, mixed at one time

25、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 electrodes, and the sheath (strip or tubing of tubular cored electrode wire and rod), material obtained from one furnace

26、 melt, where slag-metal or gas-metal reactions occur in producing the metal 2.4.2 heat induction melting in a controlled atmosphere or in a vacuum for consumable inserts, solid wires, rods and strip, core wire for covered electrodes, and the sheath (strip or tubing of tubular cored electrode wire an

27、d 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 the chemical composition range approved by the purchaser of the material (i.e. the producer of the welding consumabl

28、e) 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 covered electrodes, and the sheath (strip or tubing of tubular cored electrode wire and rod), an uninterrupted series

29、of remelts in one furnace under the same remelting conditions using one or more consumable electrodes produced from a heat, as defined, each remelt conforming to the chemical composition range approved by the purchaser of the material (i.e. the producer of the welding consumable) in processes involv

30、ing 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 (strip or tubing) for tubular cored electrodes and rods shall be applied as listed in 3.2 to 3.3.1. Identification of co

31、vering 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 number Consumable inserts, solid wires, rods and strip, core wire for covered electrodes, and the sheath (strip or tubi

32、ng) for tubular cored electrodes and rods, identified by heat number, shall consist of material from a single heat of metal. BS EN ISO 14344:2010ISO 14344:2010(E) ISO 2010 All rights reserved 33.3 Controlled chemical composition 3.3.1 Consumable inserts, solid wires, rods and strip, core wire for co

33、vered 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 more heats from which samples have been taken for chemical analysis. The results of the analysis o

34、f 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 permit spliced-coil practice shall be sampled on both ends and shall have no more than a single splic

35、e 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 all wet mixes within the lot are equivalent. These tests shall include chemical analysis, the res

36、ults 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 of wet mixes is controlled by raw material analysis and computerized weighing, it can be assumed

37、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 sufficient tests to ensure that all dry blends within the lot are equivalent. These tests shall

38、 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 of dry blends is controlled by raw material analysis and compu

39、terized 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 2.3) or by controlled chemical composition (see 3.3.2). A covering identified by wet mix shall

40、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 shall be identified either by dry blend (see 2.2) or by controlled chemical composition (see 3.3

41、.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 arc welding, the flux ingredients shall be identified either by dry blend (see 2.2) or by contro

42、lled 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 controlled chemical composition (see 3.3.2). Fluxes identified by dry blend shall consist of a single

43、 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 lot of bare solid electrodes and rods or consumable inserts is the manufacturers standard lot, as
