Foreword
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
committees. 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 International 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 3.
The main task of technical committees is to prepare International Standards. Draft International 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.
Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 14344 was prepared in collaboration with the International Institute of Welding which
has been approved by the ISO Council as an international standardizing body in the field of welding.
INTERNATIONAL STANDARD ISO 14344:2002(E)
Welding and allied processes — Flux and gas shielded electrical
welding processes — Procurement guidelines for consumables
1 Scope
This International Standard is a tool for communication between a purchaser and a supplier of welding
consumables within quality systems as might, for example, be based upon ISO 9001. This International Standard,
together with an 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 ISO or other welding consumable standard);
b) the lot classification (selected from Clause 5 of this International Standard);
c) the testing schedule (selected from Clause 6 of this International Standard).
Selection of the specific welding consumable classification, lot classification and testing schedule will depend upon
the requirements of the application for which the welding consumable is being procured.
2 Normative reference
The following normative document contains provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of this
publication do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent edition of the normative document indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
ISO 9001, Quality management systems — Requirements
3 Terms and definitions
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, 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 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 material later, in those cases in which
identification is necessary.
For the purposes of this International Standard, the following terms and definitions apply.
3.1
dry batch
quantity of dry ingredients mixed at one time in one mixing vessel
ISO 14344:2002(E)
NOTE Liquid binder, when added to a dry batch, produces a wet mix. A dry batch may be divided into smaller quantities, in
which case addition of the liquid binder produces as many wet mixes as there were smaller quantities.
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 which, when the
liquid binder is added, produce one or more wet mixes.
3.3
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
3.4
heat
for consumable inserts, solid electrodes and rods, core wire for covered electrodes, and the sheath (strip or tubing
of tubular cored electrode wire and rod), one of the following, depending on the method of melting and refining of
the metal:
the material obtained from one furnace melt, where slag-metal or gas-metal reactions occur in producing the
metal (e.g., open hearth, electric arc, basic oxygen, argon-oxygen processes);
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 consumable) where significant chemical
reactions do not occur in producing the metal (e.g., induction melting in a controlled atmosphere or in a
vacuum);
an uninterrupted series 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
involving continuous melting and casting (e.g., consumable electrode remelt).
4 Identification
4.1 General
Identification of consumable inserts, solid electrode wire and strip, rods, core wire for covered electrodes, and the
sheath (strip or tubing) of tubular cored electrodes and rods shall be applied as listed in 4.2 to 4.5.
4.2 Heat Number
Solid wire, electrode core wire, rod, strip and consumable inserts, identified by heat number, shall consist of
material from a single heat of metal.
4.3 Controlled chemical composition
Solid wire, electrode core wire, rod, strip and consumable inserts 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 of each sample shall be within the manufacturer’s 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
splice per coil.

ISO 14344:2002(E)
4.4 Covering mix
In the production of covered electrodes, the covering mix shall be identified in one of the following two manners:
a) wet mix:
a covering identified by wet mix shall consist of a single wet mix for each lot of electrodes;
b) controlled chemical composition:
a covering identified by controlled chemical composition (rather than by wet mix) shall consist of one or more
wet mixes and subjected to sufficient tests
