Specification for Tungsten and Oxide Dispersed Tungsten Electrodes for Arc Welding and Cutting Packaging and Quality

Packaging

1. Marking of packages

The following information, as a minimum, shall be legibly marked so as to be visible from the outside of each package:
a. The number of this Standard, i.e., AWS A5.12M/A5.12:2009 (ISO 6848:2004 MOD);
b. Electrode diameter;
c. Electrode length;
d. Net quantity of electrodes;
e. Supplier’s name and trade designation;
f. Lot, control, or heart number.

2. Packing

Tungsten electrodes shall be packed so that their surfaces are protected from all damage or staining when they are properly transported and stored.

3. Marking of over-packing

Marking of any, or all, over-packing of unit packages with items listed in 11.1 shall be optional with the manufacturer.

4. Warning label

The appropriate precautionary information as given in ANSI Z49.1, latest edition (as a minimum) or its equivalent, shall be prominently displayed in legible print on all packages of electrodes, including individual unit packages enclosed within a larger package.

Electrode quality

The surface of electrodes shall be free of impurities, undesirable films, foreign inclusions, cracks, scale and other defects. Electrodes shall be internally free of foreign inclusions or anything else that would adversely affect the operation of the electrode. Oxide additions shall be sufficiently uniformly distributed throughout the electrode so that the operation of the electrode is not adversely affected.
