Heading
Points : Heading, Definition Definition ‘Heading’ or ‘up-set’ forging is employed extensively for the manufacture of bolts, rivets and other components, where an increase in diameter is necessary without loss of strength and shock-resistance.
The stock bar is heated for a portion of its length and then forged, in a machine which also parts off the components. It will be obvious, that a bolt head forged in this way will be much stronger than one which has been machined from a bar, since forging does not cut into the fibrous structure of the material and thus introduce planes of weakness into the finished bolt head.
