FORGING NC II – TESDA COURSE MODULE

TESDA TRAINING REGULATIONS FOR FORGING NC II

The FORGING NC II consists of competencies that a person must achieve to be able to perform hand and hammer forging of low to medium carbon and alloy up to steel carbon and alloy steels using a variety of techniques, tools, formers and heating devices. It also include basic incidental heat/quenching, tempering and annealing of ferrous and non-ferrous metals of various types and thicknesses.

Forging is the term for shaping metal by using localized compressive forces. Cold forging is done at room temperature or near room temperature. Hot forging is done at a high temperature, which makes metal easier to shape and less likely to fracture. Warm forging is done at intermediate temperature between room temperature and hot forging temperatures. Forged parts can range in weight from less than a kilogram to 170 metric tons. Forged parts usually require further processing to achieve a finished part.

A student who has achieved this TESDA Course in FORGING NC II is competent to be:

  • Blacksmith; or
  • Hammer smith

DEFINITION OF TERMS (FORGING)

  • Forging – Forging is the term for shaping metal by using localized compressive forces
  • Cold forging – Cold forging is done at room temperature or near room temperature.
  • Hot forging – Hot forging is done at a high temperature, which makes metal easier to shape and less likely to fracture.
  • Warm forging – Warm forging is done at intermediate temperature between room temperature and hot forging temperatures.
  • Hammer forging – In modern times, industrial forging is done either with presses or with hammers powered by compressed air, electricity, hydraulics or steam. These hammers are large, having reciprocating weights in the thousands of pounds. Smaller power hammers, 500 lb (230 kg) or less reciprocating weight, and hydraulic presses are common in art smithies as well. Steam hammers are becoming obsolete.
  • Open-die forging – Open-die forging is also known as smith forging. In open-die forging a hammer comes down and deforms the workpieces, which is placed on a stationary anvil. Open-die forging gets its name from the fact that the dies (the working surfaces of the forge that contract the workpiece) do not enclose the workpiece, allowing it to flow except where contacted by the dies. Therefore the operator needs to orient and position the workpiece to get the desired shape. The dies are usually flat in shape, but some have a specially shaped surface for specialized operations. For instance, the die may have a round, concave, or convex surface or be a tool to form holes or be a cut-off tool.
  • Impression-die forging – Impression-die forging is also called closed-die forging. In impression-die work metal is placed in a die resembling a mold, which is attached to the anvil. Usually the hammer die is shaped as well. The hammer is then dropped on the workpiece, causing the metal to flow and fill the die cavities. The hammer is generally in contact with the workpiece on the scale of milliseconds. Depending on the size and complexity of the part the hammer may be dropped multiple times in quick succession.
  • Flash Excess metal – is squeezed out of the die cavities; this is called flash. The flash cools more rapidly than the rest of the material; this cool metal is stronger than the metal in the die so it helps prevent more flash from forming. This also forces the metal to completely fill the die cavity. After forging the flash is trimmed off
  • Press forging – Press forging is variation of drop-hammer forging. Unlike drop-hammer forging, press forges work slowly by applying continuous pressure or force. The amount of time the dies are in contact with the workpiece is measured in seconds (as compared to the milliseconds of drop-hammer forges). The press forging operation can be done either cold or hot.
  • Upset forging – Upset forging increases the diameter of the workpiece by compressing its length. Based on number of pieces produced this is the most widely used forging process. A few examples of common parts produced using the upset forging process are engine valves, couplings, bolts, screws, and other fasteners.
