INTRODUCTION

a.
This section is to be used as a guide to the types of weld joints that maybe used to repair
component parts. The weld procedures contained in section 6 describe the techniques employed
to manufacture the original components and therefore represent the types of welds and the
welding parameters that may be used to repair the components should they become damaged.
As it is not possible for all types of damage to be covered by these procedures they are to be
used as a guide only. Further welding information maybe gained from TC 9-237,
http://www.adtdl.army.mil/cgi-bin/atdl.dll/tc/9-237/toc.htm, however the equipment and processes
described within this manual are best suited to the component parts to which they refer.
b.
In general weld repairs should only be carried out where damage has caused existing
welds to crack or to repair plates bent through impact. If the integrity of the component can not be
assured after a repair then the component should be replaced. Weld repairs should only be
performed when replacement parts are not available. The defective component should be
replaced at the earliest opportunity.
c.
The processes involved to produce the repair are described in section 2, followed by the
inspection requirements in section 3. Section 4 contains a list of the expendable and durable
items required to achieve the repairs. Section 5 includes a list of all the components considered
repairable along with a set of component sketches showing weld locations and the weld
procedure to use. These weld procedures are detailed in section 6 and these show the weld type,
the size range, the welding settings and the consumables required.
d.
The weld procedures often refer to various plate thickness and therefore the weld
parameters should be adjusted within the specified ranges to suite the welding equipment and the
plate thickness to be repaired.
