Introduction

Most of the metals and alloys used in Army materiel can be either

welded or machined.

Repair part components, such as gears, shafts,

and wheel vehicle body and tank hull components, can be repaired or

fabricated.

Repair or fabrication involves the employment of the

various welding or machining processes available to intermediate

direct

support

(IDS)

and

intermediate

general

support

(IGS)

maintenance units in the field.

Hardware items such as nuts, bolts, screws, pins, and fuel line

fittings can be machine fabricated, however, repair parts such as

these are not always readily available in a combat situation.

Further, such items as jigs and devices used in the repair of

materiel are not stocked in the supply system.

To compensate for

these situations, IDS and IGS maintenance units in the field carry a

supply stock of various metals from which to fabricate and/or
