The video starts by outlining the basic techniques of resistance spot welding. Extensive use of animation illustrates the three essential principles involving: adjustment of welding current values - electrode force - and current flow time. The effect of spot welds when these principles are correctly and incorrectly applied are clearly shown. Examples of stationary and portable spot welding applications in industry are included and the film concludes by indicating some of the problems which arise in resistance welding: these will be dealt with in Resistance Welding - Advanced which covers further variations of resistance welding.
