4.3.2.1 Where lot identification is by heat of core wire (see 4.4.1.3).
(a) The lengths of the electrodes, and diameter of coating and core
wire.
(b) Type and class under which approval is desired.
(c) Composition of core wire and coverings in terms of nominal
percentages for each constituent.
(d) Composition of the deposited weld metal.
(e) Recommended amperages for each weld test.
(f) Brand name.
4.3.2.2 Where lot identification is by controlled core wire chemical
composition (see 4.4.1.4.2).
In addition to 4.3.2.1, the following shall be
furnished for approval by NAVSEA:
(a) Chemical composition control limits in core wire of each MIL-type
electrode.
(b) Method of determining core wire chemistry.
(c) Production line methods used to produce electrodes from chemically
controlled core wire.
(d) Procedure for control of moisture content between baking and
packaging.
4.3.2.3 Where lot identification is by controlled covering mixture chemical
composition (see 4.4.1.2.2). In addition to 4.3.2.1 or 4.3.2.2 the following
shall be furnished for NAVSEA approval:
(a)
Percent allowable variation (disclosed) from standard (not
disclosed) for each chemical element in the covering mixture of
each MIL-type electrode:
(b) Method of determining covering mixture chemistry.
(c) Production line methods used to produce electrodes from chemically
controlled covering mixture.
(d) Procedure for control of moisture content between baking and
packaging.
4.3.3 Samples for qualification inspection.
Each manufacturer shall
furnish sample packages and electrodes of the type he desires to have inspected.
Quantities shall be as requested by the qualifying activity or laboratory, and
shall be selected at one time in the presence of the Government representative
and so indicated. The manufacturer shall indicate on the sample whether the
electrodes and packages were produced on a laboratory or experimental scale, or
on a production scale.
4.4 Quality conformance inspection.
4.4.1 General. Electrodes shall be inspected in accordance with the
definitions and identification of materials specified (see 4.4.1.1 through
4.4.1.4) and to inspection level A, B, C, or D as specified (see 4.4.2 through
4.4.5 and 3.1). Sample electrodes shall be subjected to the examinations and
tests in 4.5 and 4.6 as specified in the applicable detail specification (see 3.1
and 6.3).
