3. Terms and Definitions
In production, the components of welding or brazing 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 or brazing consumable. This designation stays with the welding or brazing consumable and can be used to identify the material later, in those cases in which identification is necessary.
AWS A3.OM/A3.O, Standard Welding Terms and Definitions, provides the basis for terms and definitions used herein. However, the following terms and definitions are included below to accommodate usage specific to this document.
3.1 Dry Batch. The quantity of dry ingredients mixed at one time in one mixing vessel.
NOTE: Liquid(s), such as binders, when added to a dry batch, produce a wet mix. A dry batch may be divided into homogeneous smaller quantities, in which case addition of the liquid(s) produces a corresponding number of smaller wet mixes.
3.2 Dry Blend. Two or more dry batches from which quantities of each arc 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.
3.3 Wet Mix. The combination of liquid(s) and a dry batch, dry blend, or a portion thereof, mixed at one time in one mixing vessel.
3.4 Heat. For fully metallic consumables, or the fully metallic rod, tube, or strip used to fabricate tubular cored or covered electrodes and rods the following apply. The specific definition is dependent on the method of melting and refining of the metal:AWS A5.01M/A5.01:2019 pdf free download.
