| Footage description: | Charles Newey stands next to a Ford 'Model T' motorcar. He describes the principal functions of a car body and how the 'Model T' meets these conditions. Animated cartoon showing horse drawn carriages and very early automobiles. Commentary discusses the evolution of car body design. Newey with a 1903 De Dion. He points out several design features of this car, particularly frame design. Newey examines a 1902 Pollard. This model has a wooden body and frame. Newey points out and discusses the components. Newey with a 1913 Argyle chassis. This model has all steel, channel sectioned members making up the chassis. Newey describes its components. Newey with the Model T Ford again. The chassis of this car is examined. Newey provides the commentary. Newey with a 1934. Citroen saloon. This model ias an all steel body. Newey uses an animated diagram of this car to show how it differed from others of its time (no frame was used). Shots of modern car bodies go ing through the assembly line. (These are built on the same principle as the Citroen above). Shots of car body components being pressed and joined on the assembly line. Shot of assembly line control room for a car assembly plant. Shots and animated diagrams of a Morris Marina coupe body. Commentary by Newey describes the components which make up the completed body. Pressing and assembly of a Morris Marina coupe body shown. Commentary by Newey explains what is happening. Close up shots of steel pressing machines. Newey explains the materials aspects of the pressing operation. Problems of plastic flow in steel during pressing discussed. Shots of tensile testing of a steel sheet. Shots of steel sheets which make up car bodies being stretched before pressing. Shots of pressed body components being trimmed in other presses. A series of operations are required to finish the components and are shown. Shots of automatic welding machines working on body components. The spot welding operation is shown in close up. Animated diagram shows the spot welding process. Commentary by Newey describes what is happening. Close up shot of an actual spot weld being made. The action is slowed. Further shots of spot welding done by automatic machines. Shots of part of the electronic control system of the automatic spot welder. Further shots of the automatic spot welder at work. Shots of car body components being tested to destruction to check the spot welds. Testing is done by hand. Shots of sample spot welds undergoing tensile testing in a testing machine. A good weld is demonstrated. Continuing shots of spot weld testing by hand on the assembly line. A bad weld is shown. Further shots of laboratory tensile testing of spot welds. Properties of a bad spot weld are shown. Shots of car body components being welded by hand. Shots of an assembled car body moving along the assembly line. Newey sums up the programme. |
