AWS A5.01M-A5.01:2013 pdf download.Welding Consumables - Procurement of Filler Metals and Fluxes
1 Scope
AWS A5.01M-A5.01 identifies various information necessary for communication between a purchaser and a supplier of welding consumables. This standard, together with an AWS, ISO, or other recognized welding consumable standard, provides a method for preparing those specific details needed for welding consumable procurement which consist of the following:
a) the welding consumable classification (selected from the pertinent AWS, ISO, or other applicable welding consumable standard);
b) the lot class (selected from Clause 4 of this standard);
c) the testing schedule (selected from Clause 5 of this standard).
Selection of the specific welding consumable classification, lot class and testing schedule will depend upon the requirements of the application for which the welding consumable is being procured.
2 Normative References

Members of ISO and IEC maintain registers of currently valid International Standards.
3 Terms and Definitions
In production, the components of welding consumables shall be divided into discrete 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, each 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 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 material later, in those cases in which identification is necessary.
3.2 Dry Blend
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 one large mixer.
NOTE: A dry blend, as in the case of a dry batch, may be used singly or divided into smaller quantities, in which case addition of liquid(s) produces a corresponding number of smaller wet mixes.AWS A5.01M-A5.01 pdf download.
