Explains the basic principles involved in welding with covered electrodes. Includes: the welder’s need for protective clothing, how the workpiece/power supply electrical connections are made, striking an...
Covers 13 different welding processes and most of these are shown in production environments where emphasis is placed on reliability and cost-effectiveness. Examples of mechanisation, automation and robotics...
The strength of welded joints can be seriously reduced by defects, both those introduced during welding and those which arise in service, such as fatigue cracks. For both critical welded joints in new...
Demonstrates the main characteristics of electron-beam weld, the narrow melted zone and the depth-to-width ratio. Animation is used to explain the principles of the process and to illustrate the keyhole mode...
The third in a series of films demonstrating the industrial potential of the results of specific research at the Institute. Recapitulates the advantages of conventional friction welding and its disadvantages...
Covers the main techniques used for the non-destructive testing (NDT) of welded joints - penetrants, magnetic particle, radiography and ultrasonics. Shows the operating principles of each and the measurement...
Using high-speed photography, explains the basic principle of friction welding in detail and shows several production examples. The industrial applications range from automobile parts, chemical plant,...
An introduction to modulated current systems for DC tungsten inert-gas (TIG) welding. Opens with some general information about the basic TIG process, and then proceeds to the addition of pulses of current,...
High-speed cinematography, in conjunction with special half-section projections and electrodes, is used to illustrate the behaviour of projections of various heights and shapes.
