Method for controlling machine parameters in friction welding

摘要

In vibration welding the process takes place in a number of phases. The quality of the welding connection depends on which phase is reached during vibration and which conditions prevail in the phase 3 of the vibration process. According to the invention the welding machine is provided with a measuring and controlling system for the displacement distance to determine when the phase 3 of the process is safely reached and to control the joining velocity in this phase.
