Description
The programme, filmed at the Walter Somers Haywood Forge in Birmingham, investigates changes induced in metals during forging and how they are manipulated to give forged products good resistance to... the stresses they experience in service.

Footage description: Film shots of a crankshaft being forged. Commentary by Mike Wise introduces the programme. Mike Wise and Rex Bayliss, standing next to a forged propeller shaft, discuss the types of products which are forged at the Haywood Forge. They explain why forging is preferred to casting for these products. Wise and Bayliss, next to a 30 ton ingot, discuss the properties of the ingot which will be forged into a product. Film of an ingot in the furnace at Haywood, then being lifted out of the furnace and moved to the forge. Commentary by Wise explains the importance of correct working temperature for the ingot. Film of a hot ingot in the forge being worked into an intermediate shape called a bioom. Wise explains what is happening. Film of a bloom under the press. Commentary by Wise explains what is happening to the metal inside the bloom. An animated diagram also helps to illustrate the process. Using another animated diagram and film of a bloom in the press, Wise explains the details of forging a specific item, in this case a prop shaft. To illustrate the forging of a very difficult product, one that has a particularly demanding tri-axial stress loading, film shots of a drop forging die being made. Commentary by Mike Wise explains the process and points out the problems. Mike Wise very briefly sums up the advantages of the forging process. Rex Bayliss, over film of forge workers, points out the skill and training required for this work.
