A Study on the Trial Manufacture of a Friction Welding Machine made by Rebuilding an Engine Lathe : Mechanical features and effects of its performance

In Japan，since 1963 the friction welding process has been developed and it has prevailed rapidly. Then lately its benefits and features have been questions general interest for the manufacturing industry. In this circumstance，in order to apply this process comparatively simply， authors has intended to research the trial manufacture of a simple friction welding equipment which has the adaptable mechanism and performance to desirable usage at each production shop or laboratry，etc. For this purpose， we have designed and made a friction welder by rebuilding a used engine lathe and have made several tests and experiments concerning mechanical features and the effects of its performance. The result of this investigation has made it clear that in spite of limitation of the properties of the lathe rebuilt，the new machine is of practical use and nearly coordinates in function with other ordinary friction welders in principle.And it seems to approximately satisfy our expetation
