PREFACE
WELDING CONSUMABLES FOR USE WITH FERROUS ARMOUR
a. This standard specifies requirements for welding consumables for use on ferrous armour
for Ministry of Defence use.
b. This standard has been produced on behalf of the Standardization Advisory Group
(SAG) by the Corrosion Prevention and Metallic Materials Standards Production Group (E3).
c. This standard has been agreed by the authorities concerned with its use and is intended to
be used whenever relevant in all future designs, contracts, orders etc and whenever practicable
by amendment to those already in existence. If any difficulty arises which prevents application
of the Defence Standard, the Directorate of Standardization (DStan) shall be informed so that a
remedy may be sought.
d. Any enquiries regarding this standard in relation to an invitation to tender or a contract in
which it is incorporated are to be addressed to the responsible technical or supervising authority
named in the invitation to tender or contract.
e. Compliance with this Defence Standard shall not in itself relieve any person from any
legal obligations imposed upon them.
f. This standard has been devised solely for the use of the Ministry of Defence (MOD) and
its contractors in the execution of contracts for the MOD. To the extent permitted by law, the
MOD hereby excludes all liability whatsoever and howsoever arising (including, but without
limitation, liability resulting from negligence) for any loss or damage however caused when the
standard is used for any other purpose.

TEXT
Welding Consumables for Use with Ferrous Armour
SECTION 1 GENERAL REQUIREMENTS
1 SCOPE
This standard classifies arc welding consumables for the fabrication of all ferrous armour
structures and components.
2 WARNING
The Ministry of Defence (MOD), like its contractors, is subject to both United Kingdom and
European laws regarding Health & Safety at Work, without exemption. All Defence Standards
either directly or indirectly invoke the use of processes and procedures that could be injurious
to health if adequate precautions are not taken. Defence Standards or their use in no way
absolves users from complying with statutory and legal requirements relating to Health &
Safety at Work.

SECTION 1 GENERAL REQUIREMENTS
3.4 DStan can advise from where related documents can be obtained. Requests for such
information can be made to the DStan Helpdesk. How to contact the helpdesk is shown on the
outside rear cover of Def Stans.
4 GENERAL
4.1 All welding defined in the classes listed in clause 5, when applied to armoured vehicles
or their components, shall comply with the requirements of this Standard, in addition to those
defined in Def Stan 03-34.
4.2 The consumables employed for welding armour materials shall be validated in
accordance with the requirements of Def Stan 01-10.
NOTE: A list of consumables, validated to Def Stan 01-10, is obtainable from the responsible
technical and supervising authority.
4.3 When welding non-armour components to armour, the requirements of the armour shall
take precedence.
4.4 In the following text all references to armour should be taken to mean Def Stan 95-23,
Def Stan 95-24, Def Stan 95-25 and Def Stan 95-26 (or their predecessors).
4.5 Welding operations shall be carried out using the manufacturer's recommended welding
parameters.

SECTION 2 CONSUMABLE CLASSES
5 CLASSES OF CONSUMABLE
5.1 The welding consumables are classified according to type (e.g. austenitic metal arc
electrodes), welding position (e.g. flat), as defined in ISO 6947, and parent plate thickness (e.g.
all thicknesses).
5.2 The maximum permissible heat inputs for consumables in all classes (except Class 6) is
defined in Table A.
6 DEF STAN 01-9 CLASS 1A
These are austenitic electrodes for welding armour in the downhand (PA) and horizontal-vertical
(PB, PC) positions. Electrodes may be validated for welding armour in all thicknesses (Class
1Aa) or up to 14 mm only (Class 1Ab).
7 DEF STAN 01-9 CLASS 1B
These are austenitic electrodes for welding armour in the vertical-up (PF), overhead (PE) and
horizontal-overhead (PD) positions. Electrodes in this class may be validated for welding
armour in all thicknesses (Class 1Ba) or up to 14 mm only (Class 1Bb).
8 DEF STAN 01-9 CLASS 2A
These are austenitic, gas shielded, flux cored wires, for welding armour in the downhand (PA)
and horizontal-vertical (PB, PC) positions. Such wires may be validated for welding armour in
all thicknesses (Class 2Aa) or up to 14 mm only (Class 2Ab).
9 DEF STAN 01-9 CLASS 2B
These are austenitic, gas shielded, flux-cored wires, suitable for welding armour in the vertical-
up (PF), overhead (PE) and horizontal-overhead (PD) positions. Such wires may be validated for
welding all thicknesses (Class 2Ba) or up to 14 mm only (Class 2Bb).
10 DEF STAN 01-9 CLASS 3A
These are austenitic self shielding flux cored wires, for welding armour in the downhand (PA)
and horizontal-vertical (PB, PC) positions. Such wires may be validated for welding armour in
all thicknesses (Class 3Aa) or up to 14 mm only (Class 3Ab).
11 DEF STAN 01-9 CLASS 3B
These are austenitic flux-cored wires, used with a gas shield, suitable for welding armour in the
vertical-up (PF), overhead (PE) and horizontal-overhead (PD) positions. Such wires may be
validated for welding all thicknesses (Class 3Ba) or up to 14 mm only (Class 3Bb).

thicknesses (Class 4Aa) or up to 14 mm only (Class 4Ab).
13 DEF STAN 01-9 CLASS 4B
These are low hydrogen ferritic electrodes for welding armour in the vertical-up (PF), overhead
(PE) and horizontal-overhead (PD) positions and may be validated for armour in all thicknesses
