TITLE: FORGING JOB

STUDENT ACTIVITY:

1. Learns about hot & cold smithy process.
2. Student prepares one job by hot smithy & forging process.
3. Student prepares one job by cold forging process at.

Smithy process




 Blacksmiths work by heating pieces of wrought iron or steel until the
metal becomes soft enough for shaping with hand tools, such as a
hammer, an anvil and a chisel. Heating generally takes place in coal,
charcoal or coke.
 Color is important for indicating the temperature and workability of
the metal. As iron heats to higher temperatures, it first glows red,
then orange, yellow, and finally white.
 The ideal heat for most forging is the bright yellow-orange color that
indicates forging heat. Because they must be able to see the glowing
color of the metal, some blacksmiths work in dim, low-light
conditions, but most work in well-lit conditions.
 The key is to have consistent lighting, but not too bright. Direct
sunlight obscures the colors.
 Forging—the process smiths use to shape metal by hammering—
differs from machining in that forging does not remove material.
Instead, the smith hammers the iron into shape.
