Process and apparatus for controlling the machine parameters in friction welding

摘要

In linear vibration welding, the welding process can be subdivided into a number of phases. The quality of the welded joint depends on which phase is reached during vibration and which conditions prevail in process phase 3 of the vibration. According to the invention, the machine is provided with a measuring and controlling system for the joining path, in order to determine in a simple way when process phase 3 is reached and to carry out controlling of the joining rate in this phase. ……
